Cannot find module 'babel-core' #124

DamienCassou · 2017-08-29T15:09:56Z

I've just updated from 6.1.2 to 7.0.0 and I now get this error message:

[17:08:05] 'requirejs' errored after 68 ms
[17:08:05] Error: Cannot find module 'babel-core'

Install babel-core as your dev dependency and it will work.

npm install --save-dev babel-core babel-preset-env

Update

As of babel 7, install the dependency via the following command instead

npm install --save-dev @babel/core @babel/preset-env

loganfsmyth · 2017-09-04T02:50:40Z

The messaging from npm probably isn't super obvious, but yeah this was a change in 7.0. babel-core is now expected to be a peer dependency. When I install it on my machine for instance:

$ npm i gulp-babel
/private/tmp
├── UNMET PEER DEPENDENCY babel-core@6 || 7 || ^7.0.0-alpha || ^7.0.0-beta || ^7.0.0-rc
└─┬ gulp-babel@7.0.0 
 
<<  a bunch of stuff I removed  >>

npm WARN gulp-babel@7.0.0 requires a peer of babel-core@6 || 7 || ^7.0.0-alpha || ^7.0.0-beta || ^7.0.0-rc but none was installed.

which tries to convey this, but unless you're looking for it, it's pretty easy to miss.

DamienCassou · 2017-09-04T10:02:46Z

Thank you, this worked. The release notes say:

made babel-core a peerDependency instead of dependency and supports v6/v7/(alpha/beta/rc for v7)

could you please make it a bit more explicit that something is required from the users? A note in the README would be nice as well.

dduvanpantoja · 2018-01-30T17:46:19Z

Thanks @abbassiddiqi,Thanks, but why I have to install this module by separated.

sylbru · 2018-01-31T15:14:15Z

The Setup page in the docs on babeljs.io doesn't mention this either:

npm install --save-dev gulp-babel

demurgos · 2018-01-31T16:47:25Z

Agreed, the setup page should be updated.
The npm page (for 7.0.1) and Github README (for the beta version) are up-to-date so I recommend to check them.

@Duvan01
Having babel as a peer dependencies allows the main project to pick the version of Babel it wants without waiting for gulp-babel to be updated. Still, I'd prefer it to work out-of-the box. We may consider a setup where a default Babel is provided but you can supply your own version too.

zaojiahua · 2018-03-15T06:54:58Z

Install babel-core as your dev dependency and it will work.

this not works for me.

krshubham · 2018-03-16T12:39:05Z

It wasn't working for me too, until I read the README.
It clearly says:
npm install --save-dev gulp-babel @babel/core @babel/preset-env
👍

AlexanderKozhevin · 2018-04-02T19:44:05Z

I keep getting an error on windows machine.

cannot find module 'babel-core'

loganfsmyth · 2018-04-02T19:50:21Z

@AlexanderKozhevin When installing, you need to install that too: https://github.com/babel/gulp-babel/tree/v7-maintenance#install

AlexanderKozhevin · 2018-04-02T19:51:41Z

@loganfsmyth thanx!

`babel-core` is now expected to be a peer dependency. babel/gulp-babel#124

lasalu99x · 2018-09-14T11:10:06Z

I could fix it by this link

https://github.com/babel/babel-loader

basickarl · 2018-09-20T08:50:34Z

npm i @babel/core

NhatNam98 · 2018-11-10T06:46:50Z

Thanks you so much

gpresland · 2018-11-28T17:02:26Z

Babel 6:

npm install --save-dev The following:

@babel/cli
@babel/core
@babel/preset-env

Babel 7:

npm install --save-dev The following:

babel-cli
babel-core
babel-preset-env

primexpy · 2019-01-01T07:49:11Z

@abbassiddiqi thank you very much!it worked

The current reasonml needs an example of how to do getInitialProps. tmepple posted the only known way of doing it in [this comment](#4202 (comment)). It is unlikely reasonml users are going to discover that comment or figure it out on their own so having it in an example is critical. Also, dependencies updated. After updating dependencies, I get this error: ``` ModuleBuildError: Module build failed (from ./node_modules/next/dist/build/webpack/loaders/next-babel-loader.js): [1] Error: Cannot find module '@babel/core' [1] babel-loader@8 requires Babel 7.x (the package '@babel/core'). If you'd like to use Babel 6.x ('babel-core'), you should install 'babel-loader@7'. ``` Seems like @babel/core is required as peer dependency per [this comment](babel/gulp-babel#124 (comment)) so I added it. The way to do getInitialProps has changed in 7.0.2 canary so this also has a comment in the code about what change is required to get that working.

SamuSan · 2019-03-12T00:33:56Z

Babel 6:

npm install --save-dev The following:
@babel/cli
@babel/core
@babel/preset-env
Babel 7:

npm install --save-dev The following:
babel-cli
babel-core
babel-preset-env

For anyone finding themselves down this rabbit hole, this comment is the exact opposite of reality. Babel 7 moved to the @babel namespace.

luku · 2019-03-26T22:28:27Z

For me the only working solution for Babel 7 was from Babel setup guide. Note the gulp-babel@next

npm install --save-dev gulp-babel@next @babel/core @babel/preset-env

aggregate1166877 · 2019-09-30T03:29:00Z

Thought I'd add my own solution: delete package-lock.json and try again.

I have this issue crop up from time to time. Deleting package-lock.json solves it every time.

anusharma9462 · 2019-10-25T12:51:23Z

still getiing the same error., please help me out. i tried

Just go inside the babel-loader and change the require("babel-core")----to ----require("@BabelCore")

As of babel 7, install the dependency via the following command instead

After all,do this also .Just go inside the babel-loader and change the require("babel-core")----to ----require("@BabelCore")

If you are using @babel-core (v7.0+) you need to upgrade to the latest version of babel-loader (v8.0) simply run this command.

npm install -D babel-loader@8.0.0
