Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3" #522
Comments

Please any help ? I installed updated version for babel 7 but this error displays in console while I run npm start or npm install. Error: Requires Babel "^7.0.0-0", but was loaded with "6.26.3". If you are sure you have a compatible version of @babel/core, it is likely that something in your build process is loading the wrong version. Inspect the stack trace of this error to look for the first entry that doesn't mention "@babel/core" or "babel-core" to see what is calling Babel. (While processing preset: "C:\Users\japolinar\Documents\orion-github\pt-orion-rh\node_modules\@babel\preset-env\lib\index.js") |

@PT-Jessica try this
it got rid of the error for me by creating a bridge that supports babel 6 & 7 |
|
I have a similar issue on a fresh clone of the repository, here‘s more info: @joeLloyd tip doesn’t seem to work for me. |
|
Can someone provide a repo that demonstrates this issue so that I can investigate further? |
|
you can use |
|
please help me to resolve compatibilty issue. "dependencies": {
|
|
npm install --save-dev babel-loader@^8.0.0-beta https://webpack.js.org/loaders/babel-loader/ You are using babel-core instead of @babel/core, installing babel-loader@^8.0.0-beta will use @babel/core and should fix the issue |
|
@rmc33 tried ur solution, giving me this upon installation: No matching version found for babel-loader@8.0.0-beta any idea why? |
|
Hi @rayj10 |
|
@rmc33 Ah yes i see thanks for the pointers! 😄 |
|
@rayj10 no problem, as you can see babel-core changed to @babel/core at version 7 which will cause these problems if you are still using loaders, plugins or presets that use babel-core, maybe you need to keep babel-core for some time or go ahead and upgrade if they are available for @babel/core. |
|
I would recommend using Babel Upgrade and let it update all your dependencies to whats needed. |
|
@peterrattew thank you so much 🙂 that tool is priceless |
|
@PT-Jessica, @LeBenLeBen , @joeLloyd Examples: if you are using babel 7, then you have to install all dependencies with the naming convention shown above. when referencing the packages, reference them as they are too. |
|
I think the problem has to do with Jest using an older version of Babel. |
|
Maybe try forcing Jest to use babel 7. |
|
Just add |
|
Replacing all packages like 'babel-core', 'babel-cli' etc.. with '@babel/core', '@babel/cli' solve the problem. |
|
I just dealt with this issue after upgrading all of the packages in react-progressive-image. The problem there was with |
|
install "@babel/core": "^7.1.0" that will fix. |
|
For me it was as simple as: Jest was not working until I added the bridge package below @babel/core |
In addition, needed to install babel-jest and the babel-core-bridge, since apparently Jest still depends on babel 6.x. For example, see FormidableLabs/spectacle#522
|
I fix this problem with them. // babel.config.js
'use strict';
module.exports = {
presets: [
'@babel/preset-env',
'@babel/preset-react'
],
plugins: [
'@babel/plugin-transform-modules-commonjs',
'@babel/plugin-transform-object-assign',
'@babel/plugin-proposal-class-properties',
'@babel/plugin-proposal-object-rest-spread'
]
};// jest.config.js
'use strict';
module.exports = {
transform: {
'^.+\\.jsx$': 'babel-jest',
'^.+\\.js$': 'babel-jest'
}
}; |

Hi you can uninstall babel-loader and install it again to make sure webpack is still not picking up 6.26.3

Oh I see you don’t need babel-core since you have @babel/core and replace babel-cli with @babel/cli

{
"modules": false
}

「babel-core: "7.0.0-bridge.0"」はこのエラーを回避するため ``` Requires Babel "^7.0.0-0", but was loaded with "6.26.3".

Thanks for this @kevinsimper ! |

{ .babelrc Still getting the same This is the error when I write a sample ES6 component and try to compile babel to ES5 with babel server/index.js -o server/index_comp.js Is this problem still occurring or is it fixed?? |
|
@meanmachine22 if you're using the latest version of Spectacle, the expectation is that this should be fixed! |
|
maybe you could install global babel-cli, you can try command : npm uninstall -g babel-cli babel-node.you need install @babel/cli and @babel/node. |
|
If you are using babelify 7.3, update to 9.0 |
OMG BRO, YOU SAVED MY DAY! |
|
Very bizarre. Me rather, I npm uninstall babel-core: --save-dev, and it works like a charm. PS: I mean the package babel-core: ^7.0.0-bridge.0" |
|
If it does not work still when you intall babel-core ^7.0.0-bridge.0". |

� �I tried all the methods here until my colleague pointed out that I didn't remove another babel v6 package, and so it was still there in package.json. I removed it and installed a few babel v7 packages and it finally worked. this is my working .babelrc this is a part of my working package.json the key working factor for me was that I didn't remove all babel v6 related packages and so it was still conflicting with the new babel v7 stuff. I hope it will help out someone. |
Hi do you know how to remove all babel v6 related packages? |
