iOS NativeScript permission Error spawn EACCES

Question

I'm trying to set up nativescript development environment. I followed the steps as described in the official doucmentation. Link

After that I created a new Project by using

tns create my-first-app --template tns-template-hello-world-ng

Then I added iOS and Android Platform by using following command

tns platform add ios
tns platform add android

When executing

tns run android

everything works fine. The Emulator is starting and the app opens up.

However, when running

tns run ios

I get following error:

Searching for Devices...
spawn EACCES

I already tried to change permissions on app directory

sudo chmod -R a+rwx /[AppFolder]

executing

sudo tns run ios

didn't solve the problem

EDIT 2017-10-5 Responding to Nikolai Tsonevs answer:

executing the following didn't resolve the problem:

tns platform remove ios
npm cache clean --force
tns platform add ios
tns run ios

my node version is: v8.4.0 my npm version is: 5.4.2

I also executed the following to share the output with you (Assuming, that Nikolai meant ios instead of android):

tns platform remove ios
tns platform add ios --log trace > out.txt

Here's the output:

Edit: 2017-10-06 In result to Nikolay's answer I did the following:

npm i -g node-gyp
sudo gem install xcodeproj
brew install mono
brew install gradle (was not installed as well)
brew install cocoapods
brew link -overwrite cocoapods (brew was complaining about link issues)

after that I removed iOS again and added it. This didn't work as well.

I executed the following to get further information:

tns run ios --log trace > run.txt

Here is the relevant output:

Answer 1

Thanks the very great help of Nikolay I finally could resolve the problem.

Permissions where not properly set on the NativeScript node modules so I did the following:

chmod -R +x /usr/local/lib/node_modules/nativescript/

Answer 2

Could you try cleaning npm cache with

1. npm cache clean

2. remove platform with tns platform remove ios

3. add it again with tns platform add ios

4. start the application with tns run ios

If the problem still persists, could you remove again the platform with tns platform remove ios and add it again tns platform add android --log trace > out.txt Then you could share the output from the out.txt file, which could help to investigate further the problem. Also, provide an info about your node and npm versions.

Edit:

Hi @Anton Due the provided log I found that there are several errors, which are thrown while adding the platform. The first one is that the node-gyp plugin is not found. To resolve this you have two options.

The first one is to install the plugin manually with npm install node-gyp --g. If this does not resolve the case I would suggest cleaning the npm cache with npm cache clear and downgrading to the latest LTS node version 6.11.4.

Regarding the two other errors make sure that you have installed xcodeproj and cocoapods. If not install them while following:sudo gem install xcodeproj sudo gem install cocoapods
