Requires Babel "7.0.0-0" but was loaded with "6.26.3"
Keep getting this error no matter what I tried installing (babel wise) as I follow other similar reports. this is the stack trace:
error: bundling failed: 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.

Any pointers would be greatly appreciated here...
Solution 1:
Test which version you are running with cmd
babel -V
If it is not verion 7 or higher
npm uninstall babel-cli -g
npm uninstall babel-core -g
And
npm install @babel/cli -g
npm install @babel/core -g
If you are using Jest run
npm install [email protected] --save-dev
Uninstall and reinstall @babel/node solves the problem if you do node development.
Solution 2:
Looks like you need to install babel-core
as the docs suggest:
https://jestjs.io/docs/en/getting-started#using-babel
yarn add --dev babel-jest babel-core@^7.0.0-bridge.0 @babel/core regenerator-runtime
Solution 3:
Sometimes its because you have installed both babel-cli and babel/cli, or babel-core and @babel/core It causes conflicts
So
1) delete node_modules
2) remove babel-cli, babel-core from your package.json, keep @babel/core, @babel/cli
3) npm install
babel-cli conflicts with @babel/cli
bable-core conflicts with @babel/core
Solution 4:
None of the solutions I found online worked, I fixed it the following way:
- Remove
jest
and@babel/core
from package.json (keepbabel-core
v7 bridge) - Remove node_modules and package-lock.json
- npm install
- npm install jest @babel/core --save-dev
