Requires Babel “7.0.0-0” but was loaded with “6.26.3”

Question

Keep getting this error no matter what I tried installing (babel wise) as I follow other similar reports. this is the stack trace:

error: bundli         


        

Answer 1

None of the solutions I found online worked, I fixed it the following way:

1. Remove jest and @babel/core from package.json (keep babel-core v7 bridge)
2. Remove node_modules and package-lock.json
3. npm install
4. npm install jest @babel/core --save-dev

Answer 2

I accidentally had a file called .babelrc in my root directory with the following contents:

{
  "presets": ["@babel/preset-env"]
}

After I deleted that file, I no longer got this error when running my gulp command.

Answer 3

Sometimes, you have a local version, so remove it so that the global version is ran:

npm uninstall babel-cli
npm uninstall babel-core

Answer 4

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 babel-core@7.0.0-bridge.0 --save-dev

Uninstall and reinstall @babel/node solves the problem if you do node development.
