Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/tokenize' is not defined by "exports" in the package.json of a module in node_modules

This is a React web app. When I run

npm start

This error occurred

> dataflow@0.1.0 start
> react-scripts start

node:internal/modules/cjs/loader:488
      throw e;

Node.js v17.0.1

This error only occurs when I run this on this specific computer, which I do not have superuser access to. It works on other computers.

For reference, this is ./node_modules/postcss-safe-parser/node_modules/postcss/package.json

  "version": "8.2.6",
  "description": "Tool for transforming styles with JS plugins",

  },

    },
    "./": "./"

And this is what I get when I list the files in ./node_modules/postcss-safe-parser/node_modules/postcss/lib/

In my case the error was

Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/logger' is not defined by "exports" in /Users/simonebracaloni/CODE/ANCCP/anccp-etl/functions/node_modules/firebase-functions/package.json

I had to chage the import from

import { log, error } from 'firebase-functions/lib/logger';

to

import { log, error } from 'firebase-functions/logger';

For my Typescript project the problem was simply

import { renderToString } from 'react/server.js'
// instead of
import { renderToString } from 'react/server'

This compiled then crashed at runtime.

This will most likely not help the question author, since his problem is platform specific, but it's another potential cause of this error, which might help others debugging.

Make sure you are importing dependencies from correct place. I ran into:

Error: Package subpath './dist/esm' is not defined by "exports" in /node_modules/kysely/package.json

The reason being:

import { Kysely } from 'kysely/dist/esm'

Instead of:

import { Kysely } from 'kysely'

In my case, this issue occurred due to a version dependencies mismatch. You can simply upgrade your react and next version and try to install npm again by following this command:

npm install react@latest react-dom@latest next@latest --force

I updated my next and react versions using this command with a specific version as per my requirement like this,

npm install next@12 react@18 react-dom@18 --force

which worked for me. I hope you find it useful.

I was facing the similar problem with namespace.js and have solved my problem by adding the following lines

"./lib/util/namespace":"./lib/util/namespace.js"

in exports of /usr/local/lib/node_modules/generator-jhipster/node_modules/yeoman-environment/package.json

Final exports will look like

"exports": {
".": "./lib/environment.js",
"./cli/": "./cli/",
"./lib/": "./lib/",
"./lib/util/": "./lib/util/",
"./adapter": "./lib/adapter.js",
"./conflicter": "./lib/util/conflicter.js",
"./log": "./lib/util/log.js",
"./transform": "./lib/util/transform.js",
"./lib/util/namespace":"./lib/util/namespace.js",
"./package.json": "./package.json"
}

I'm also stuck with the same problem because I installed the latest version of Node.js.

For Linux users who use NVM to manage node

nvm uninstall <version>

now install the LTS version

nvm install --lts

This worked for me.

OR

Try to delete Node_modules and the lock file

  1. Delete your node_modules folder, package-lock.json or yarn.lock

  2. Re-Install all the dependencies.

    npm i

    or

    yarn

This problem can be occur when you are trying to work with an old react repository which is developed with a lower node.js version than v17.0.1 and you are currently using v17.0.1 or a higher node version.

  1. Delete your node_modules folder, package-lock.json and yarn file (if you have one).

  2. Force clean the entire NPM cache by using following command. While executing this command, you might get a warning, just ignore it.

    npm cache clean --force    //WARN using --force Recommended protections disabled.

  3. Re-Install all the dependencies.

    npm install

You don't need to roll back to older node versions.

On node.js v18 I solved it by removing the node_modules folder and the package-lock.json file:

rm -rf node_modules package-lock.json

...then running:

npm i
npm audit fix

My next npm start worked just fine.

I had the same problem 5 minutes ago, which is strange because it was working, but anyway, in my case the problem was in version 3.0 of the package "resolve-url-loader", after upgrading to version 5.0, everything has been resolved.

npm i resolve-url-loader@^5.0.0 --save-dev

If you have this package and node 17+, try to update it to the latest version, outdated versions cause problems like this.

If you hit an error in your application with Node.js 17, it’s likely that your application or a module you’re using is attempting to use an algorithm or key size which is no longer allowed by default with OpenSSL 3.0. A command-line option, , has been added to revert to the legacy provider as a temporary workaround for these tightened restrictions.ERR_OSSL_EVP_UNSUPPORTED--openssl-legacy-provider

For details about all the features in OpenSSL 3.0 please see the OpenSSL 3.0 release blog.

Contributed in https://github.com/nodejs/node/pull/38512, https://github.com/nodejs/node/pull/40478

I don't get why @AnmolNoor wants you to uninstall version 17.

The proper way:

  1. Make sure you have nvm (https://github.com/nvm-sh/nvm). If you don't, I highly recommend installing it.

  2. Check your node --version

  3. If the version is 17, this might be the reason for the error (as it was in my case)

  4. Run nvm install 14. After installing is complete, it should also switch your node version to 14.

  5. Check the version node --version just in case. If you still see 17, run nvm use 14

Your node --version should now be 14.

Note: Every time you close the current terminal tab, your default node version will return back to 17 unless you change this.

Next time you have to switch node version to 14, you don't have to install it again, just run nvm use 14

Uninstalling the current Node.js and installing LTS solves the problem, but if you want to keep the currently installed version, you could use nvs add lts to install the latest Node.js LTS, and activate it using nvs use node/<lts version>/<platform>. The LTS version and Platform values will be provided in the first command output.

I was receiving Error [ERR_PACKAGE_PATH_NOT_EXPORTED]: Package subpath './lib/parser' is not defined by "exports" in ...node_modules\next\node_modules\postcss\package.json

I have resolved it on node version 17.4.0 after I upgraded react, and nextjs using:

npm install react@latest react-dom@latest
npm install next@12

I also get the error when using Node.js v17.0.1 (Lates Features) - I am using macOS Catalina and homebrew.

So I want to switch Node.js v17.0.1 to Node.js (LTS) -> Node.js v16.3.1

I uninstall node using homebrew with the following command:

brew uninstall node

Then I download Node LTS from https://nodejs.org/en/ and install it.

enter image description here

That is work for me. Thanks :)

FWIW, I bumped into this issue on macOS Monterey with Node 17.0.1 installed via Homebrew. Downgrading to Node 16.x worked for me.

Downgrade from Node 17.x (latest) to Node 16.x using Homebrew:

brew uninstall --ignore-dependencies node
brew install node@16
brew link node@16

I faced similar issue and it was due to node version v17.1.0.

I have nvm with 3 different versions of node installed. Just switched to version v14.18.1 using nvm and the issue resolved.

If you use yarn you can:

rm -rf node_modules yarn.lock
yarn add -D react-scripts@latest
yarn build

For npm:

rm -rf node_modules package-lock.json
npm install -D react-scripts@latest
npm install
npm run build

Roll back to Node 16.8.0 or (works for me) stable version 16.13.0:

Step 1: install n

npm install -g n

Step 2: install/set node latest stable version

sudo n stable

or set 16.8.0

sudo n 16.8.0

Note, if you can't or don't want to use sudo for n, you can set environment variables for the location, eg;

export N_PREFIX=$HOME/.n
export PATH=$N_PREFIX/bin:$PATH

Remove node_modules folder and .lock file and re-install your packages (yarn or npm). It worked for me with last 17.0.1 of nodejs, I can npm (or yarn) start my app again.
