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

{
  "name": "postcss",
  "version": "8.2.6",
  "description": "Tool for transforming styles with JS plugins",
  "engines": {
    "node": "^10 || ^12 || >=14"
  },
  "exports": {
    ".": {
      "require": "./lib/postcss.js",
      "import": "./lib/postcss.mjs",
      "types": "./lib/postcss.d.ts"
    },
    "./": "./"
  },
  "main": "./lib/postcss.js",
  "types": "./lib/postcss.d.ts",
  "keywords": [
    "css",
    "postcss",
    "rework",
    "preprocessor",
    "parser",
    "source map",

    "manipulation",
    "transpiler"
  ],
  "funding": {

  },
  "browser": {
    "./lib/terminal-highlight": false,

}

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

lgtd-lt-119-mbmt:frontend juliantc$ ls ./node_modules/postcss-safe-parser/node_modules/postcss/lib/

An update to the latest version of "react-scripts" have been worked for me! Previous "react-scripts" version was 4.0.3 and I've updated to 5.0.0. Node version is 17.0.1.

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

Remove node_module & package-lock.json

then

npm install

( in install if you get error as to use --force and --legacy-peer-deps the command as

`npm install --legacy-peer-deps`

)

npm start

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.

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

After removing node_modules & package-lock.json, I ran

npm audit fix --force

& updated react-scripts to the latest available version with

npm install react-scripts@latest

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.

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

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.

I am also stuck with the same problem because I installed the latest version of Node.js (v17.0.1).

Just go for node.js v14.18.1 and remove the latest version just use the stable version v14.18.1

nvm uninstall <version>

OR

nvm uninstall v17.0.1

then install the LTS one which is v14.18.1

nvm install --lts

This worked for me.
