I get the following error the moment I install @babel/preset-env and try running a node.js file.

Requires Babel "^7.0.0-0", but was loaded with "6.26.3"

Following is the stack trace

(While processing preset: "P:\\Projects\\ReactNative\\apc-c\\node_modules\\@babel\\preset-env\\lib\\index.js")
    at throwVersionError (P:\Projects\ReactNative\apc-c\node_modules\@babel\helper-plugin-utils\lib\index.js:65:11)

    at P:\Projects\node_modules\babel-core\lib\transformation\file\options\option-manager.js:317:46
    at Array.map (<anonymous>)

I have tried a number of this from installing "7.0.0-bridge.0", etc.

Can someone please help. Have spent hours trying to fix this. Thanks

Found the problem. I had a .babelrc file that contained a reference to @babel/preset-env and transform-react-jsx. Removed them and the js file compiled just fine.

I think I can help. Been facing same issue (though not React-native just React) and just got to fix it now, can I see what your package json looks like? Maybe you can update your question with it. Also what script command produces this error?

maybe you could install global babel-cli, you can try the command

npm uninstall -g babel-cli babel-node

you need to install @babel/cli and @babel/node. OR you can uninstall node and remove the npm file in C:\Users\Administrator\AppData\Roaming

I hope I can help you. good luck
