Create-react-app: npx aborting creation

Created on 25 Apr 2020  Â·  80Comments  Â·  Source: facebook/create-react-app

The npx command is aborting and doesn't create the application.

I'm using the command:
npx create-react-app appexample

and at the end of the execution it prints:

Error [ERR_INVALID_PACKAGE_TARGET]: Invalid "exports" main target "index.js" defined in the package config /Users/alexkayser/git/apptest/node_modules/is-promise/package.json

if you just want to create react app, you can do this while waiting for a fix:
step 1: yarn init -y

step 2: Insert this to package.json

"resolutions": {
    "is-promise": "2.1.0",
    "run-async/is-promise": "2.1.0"
  }

step 3: yarn add --dev create-react-app

step 4: yarn create-react-app ../my-app

This works for me. Downgraded my node version to 12.12.0:

$ n 12.12.0
$ npx create-react-app react-sample

Works fine after that. Note that this is a temporary fix. A dependency broke (https://github.com/then/is-promise/pull/15) and they're working on it

Must use import to load ES Module: /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/index.js
require() of ES modules is not supported.
require() of /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/index.js from /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/run-async/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/gopal/.npm/_npx/21435/lib/node_modules/create-react-app/node_modules/is-promise/package.json.

Am I the only one getting this error, or is it a problem with the node package manager? I can't seem to run my application on localhost 3000 using docker-compose and its tests, should we just wait or what should I do in this scenario?

I'm using v10.16.0, shall I upgrade it to 12 or do we just have to wait until the developers fix the dependencies?

Raahul5 picture Raahul5 on 25 Apr 2020

@sabinlungudotcpp @Raahul5 Currently a Node dependency broke (https://github.com/then/is-promise/pull/15) and they're working on it. For now, the idea is to somehow downgrade that dependency to the last working version. You can try downgrade the problematic dependency by itself to v2.1.0 as mentioned here: https://github.com/then/is-promise/issues/14#issuecomment-619400516

$ npm install [email protected]

If that doesn't work, downgrade the whole thing (Node) to its last working version. Node v12.12.0 and its included dependencies works for me.

$ n 12.12.0
$ npx create-react-app react-sample

Edited for clarity.

npm uninstall create-react-app
npm uninstall -g create-react-app
npm install -g [email protected]
create-react-app --help //to check if installed correctly, should return the help info
create-react-app confusion [email protected]
cd confusion
npm start

This creates the app but unable to do yarn start or npm start

For Npm start and yarn start install
npm install [email protected] --save --save-exact

This resolved the issue for me
I'm on Node v14 latest one // resolved the must use import to load Es module //

Fixed for me

Thanks Man

They fixed the issue, npx create-react-app should be working normal again.

I was trying it for the last two hours on Mac instead of my windows machine. I thought that was the issue. Turns out it was just a problem with npm for the last few hours 🤦 ...

if you just want to create react app, you can do this while waiting for a fix:
step 1: yarn init -y
step 2: Insert this to package.json

"resolutions": {
    "is-promise": "2.1.0",
    "run-async/is-promise": "2.1.0"
  }

step 3: yarn add --dev create-react-app
step 4: node node_modules/create-react-app/createReactApp.js ../my-app

this one worked for me

worked for me as well

This should be resolved now. As @brentvatne mentioned above, if you have create-react-app installed globally, uninstalling then reinstalling should fix it. Otherwise, npx create-react-app or yarn dlx create-react-app always uses the latest version.
