react-native ios Podfile issue with "use_native_modules!"

Question

In my react-native project (react-native@0.60) in the ios/ dir I run pod install and get this error:

[!] Invalid `Podfile` file: no implicit conversion of nil into String.

 #  from /Users/coryrobinson/projects/hhs2/ios/Podfile:37
 #  -------------------------------------------
 #  
 >    use_native_modules!
 #  end
 #  -------------------------------------------

I haven't added or changed anything in this Podfile - it's all react-native generated. (I'm not experienced in iOS dev so this might be a simple fix, I just don't know what to look for :-|) Thanks for any help!

Here is my Podfile

platform :ios, '9.0'
require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

target 'hhs2' do
  # Pods for hhs2
  pod 'React', :path => '../node_modules/react-native/'

  target 'hhs2Tests' do
    inherit! :search_paths

  use_native_modules!
end

target 'hhs2-tvOS' do
  # Pods for hhs2-tvOS

  target 'hhs2-tvOSTests' do
    inherit! :search_paths
    # Pods for testing
  end

end

Answer 1

Delete node_modules
yarn cache clean
yarn install 
cd ios
pod install --repo-update

Answer 2

Alright, so nothing worked for me, but what worked for me is!

1. Deleting these files and folders from your project directory as others have already mentioned.

   • Pods/
   • Podfile.lock
   • node_modules/
   • yarn.lock
   • ios/Build/
   • ios/Pods/
   • DerivedData/

2. Use these commands to reset your Git repository and update everything:

   git reset HEAD~1 --hard    # Undo any local changes and go back one commit
   git pull                   # Get the latest code from your Git repository
   git clean -d -f -x         # Clean up any extra files and folders
   
   yarn                        # Install dependencies using Yarn
   cd ios && pod install       # Switch to the iOS directory and install CocoaPods dependencies
   

And boom... It worked!

Answer 3

All the answers above didn't work for me. I had to restart my mac and then pod install worked, without changing anything else.

Answer 4

Be sure you have a newer version of Node. When I ran expo run:ios, I got the error from the question, but no useful debug information. But, when I did

$ cd ios
$ pod install

I got the error:

React Native needs Node.js >= 16. You're currently on version v15.14.0. Please upgrade Node.js to a supported version and try again.

After switching to a newer node with

$ nvm use 20

it all worked fine.

Answer 5

Please check if this ios/chefzone.xcodeproj exists. In my case, this folder was deleted. then

yarn install, pod install, run it's working fine

Answer 6

Just delete Podfile.lock works. if you are facing issue even after all the answers. –

Answer 7

Here is the correct answer:

1 - Your Podfile should contain this line on top

require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

2 - Make sure your package.json and node_module folders has this module installed

cli-platform-ios/native_modules

3 - If you didn't find after you run yarn install - means you have old cache node_modules in your machine and you need to clean it before reinstalling the package again.

4 - Clean cache yarn cache clean

5 - Make sure you have this file react-native.config.js and its configuration is VALID - and it doesn't have non-existing NPM packages - this step is LAST AND MOSTLY THE CAUSE of the error

Example of my react-native.config.js

module.exports = {
  project: {
    ios: {},
    android: {},
  },
  assets: ['./assets/fonts/'],
  dependencies: {}, // make sure this dependencies are all valid installed packages or empty if you don't need it
};

6 - Install node packages yarn install and your pods should work now! pod install --repo-update

HAPPY coding!

Answer 8

Same issue appeared after upgrading react native from 0.65 to 0.71. Running pod install got me this:

 #  from /Users/username/Documents/projectname/ios/Podfile:25
 #  -------------------------------------------
 #  target 'projectname' do
 >    config = use_native_modules!
 #  
 #  -------------------------------------------

Executing pod install --verbose command provided the following details:

/Users/username/Documents/projectname/node_modules/@react-native-community/cli/build/bin.js error Failed to build the app: No package name found. We couldn't parse the namespace from neither your build.gradle[.kts] file at /Users/username/Documents/projectname/android/app/build.gradle nor your package in the AndroidManifest at /Users/username/Documents/projectname/android/app/src/main/AndroidManifest.xml.

During RN update I followed react native upgrade helper instructions which guided me to remove package="my.app.bundle.android" property out of manifest object in src/main/AndroidManifest.xml file. Putting it back solved my issue.

Answer 9

I too was having this very exact same issue and nothing here worked for me. In my particular case, I am using Nx monorepo tool and I had removed a package in my root level package.json, but forgot to correspondingly remove it from my Expo app package.json, so when I'd run run-ios target and it would try and build the pods, it'd fail for this reason (because symlinked package was missing). This might not be a solution for everyone, but if it'll save someone else 4 hours and a headache, why not post it 😬

Answer 10

Easily:

1. Run sudo xcode-select --switch /Applications/Xcode.app in the root of your React Native project.
2. In the ios folder run pod install.

Edit:

No hacks with any of:

• @react-native-community/cli-platform-ios
• require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'
• require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'

were needed.

Answer 11

In my case I had to switch to a newer version of node.

Answer 12

Steps to follow :

1. npm install
2. npm install -g react-native-cli
3. go to your ios folder -> cd ios
4. pod install

Answer 13

Go to this repository :ProjectName -> ios -> Podfile

1. In the Podfile, delete use_native_modules!
2. Execute again pod install
3. Enjoy your new pod

Answer 14

Having same issue while building app on AppCenter, locally works perfectly

Is there any possibility to track this error? Cause I've seen that there can be a lof of reasons why I see it.

Answer 15

Don't use yarn install. Thats what worked for me...

• Go to main folder
• Delete nodes folder
• Run sudo npm install or just npm install
• cd ios
• pod install

Answer 16

maybe its related to rights issues

adding "@react-native-community/cli-platform-ios": "3.0.0" in package.json

and

sudo chown -R user .

worked for me

Answer 17

Ok, my guess is for most people, the accepted answer will fix their issue. For me, the fix was so bizarre, I had to add it here.

For whatever reason, I ended up creating an invalid AndroidManifest.xml file in my android native setup.

I looked at the full error output, and the first lines of the error referenced a line number and column number. At that point in my xml file I broke the xml formatting.

2 days of searching to find a GitHub Issue with a description of where to look.

Answer 18

Does anyone have a consistently recreatable solution for this issue that does not revolve around getting rid of use_native_modules? I have looked into:

• Changing Ruby Version
• Changing CocoaPods version
• Invalidating NPM and Cocoapods cache

And I am unable to fix the issue. It appears to be some npm dependency, but others on my team are not seeing it.

Answer 19

Downgraded @react-native-community/cli-platform-ios from 3.1.0 to 3.0.0 and it worked.

Added

"@react-native-community/cli-platform-ios": "3.0.0"

to package.json.

Run npm install and then pod install to get it working again.

Answer 20

This started happening out of the blue today, and the problem was a space in my directory structure. Ex:

/path/to/Directory\ Name/RNProject throws the !native_modules error /path/to/DirectoryName/RNProject works as it should

Pods was looking for "Directory. "

Answer 21

Verify if you have @react-native-community/cli-platform-ios in your package.json,

if you dont run:

npm install @react-native-community/cli-platform-ios

then

cd ios && pod install

Answer 22

I got this error after I tried to react-native run-ios an Expo app. The error I got indicated that something was wrong with the Pods, so I ran cd ios && pod install, which is how I got a similar error as the OP.

In that case, you obviously need to expo start instead of react-native run-ios.

Answer 23

The issue is that:

use_native_modules!

is unsupported by earlier versions of CocoaPods. For example, our install was the app downloaded from the CocaoPods website. That version is 1.5.2.

Run:

pod --version

to check which version. If need be, uninstall and then re-install but in Terminal by running:

sudo gem install cocoapods

At least as of late October 2019, the current gem version available is 1.8.4. Once successfully installed, re-attempt the pod install and hopefully all is well.

Answer 24

For me, I deleted the node_modules and installed again by using npm install . After that, I navigated to /ios folder and ran pod install it worked.

Answer 25

this is because the outdate yarn version on your device, if you on macOS you can upgrade/install the yarn with follow this link: here it is

be aware to delete node-module and yarn.lock file, install all packages again, navigate to ios folder and run pod install.

Answer 26

One of the reasons may be outdated version of Ruby. Use following command to upgrade it.

rvm install 2.6.1
rvm use 2.6.1 --default

Or you can follow below article, which has a detailed explanation of upgrading ruby and associated gems.

https://help.learn.co/en/articles/2789231-how-to-upgrade-from-ruby-2-3-to-2-6

Answer 27

If you are using

pod install --project-directory=ios

you might need to tweak the Podfile by replacing

use_native_modules!

to

use_native_modules!(".")

Maybe this behavior will be improved in the future, I opened an issue about it https://github.com/react-native-community/cli/issues/657

Answer 28

i just dropped the whole node_modules and RN cache folder and did a clean reinstall, this fixed the "use_native_modules" problem so far....but after that i had to hassle a lot with other libs which where just not RN0.60 ready ;)

Answer 29

Getting rid of the line use_native_modules! works as well. Maybe this has been deprecated or syntax has changed? Curious to hear from others.

Update: Seems to be an issue with react-native 0.60.0. Until a release fixes this bug, 0.59.10 can be explicitly installed, and you only need to add CocoaPods as necessary.

react-native init APP_NAME --version react-native@0.59.10

Answer 30

After removing several react-native npm packages (ie: react-native-bluetooth-serial, react-native-sound, and more...) pod install works.

It appears the pod install error is related to older react-native packages that don't support cocoa pods? I'm not sure the details but removing those packages from node_modules & package.json solved my issue.
