javascript - Module build failed Cannot find module '@babelpreset-env'

I was working on my react application with set up babel. Unfortunately while setting it up using yarn and when I build my bundle.js file, I run into some problems:

ERROR in ./src/app.js
Module build failed (from ./node_modules/babel-loader/lib/index.js):

1 To me it seems like npm intall has not run properly. Did you try deleting node_modules and installing npm afresh? – ABGR Commented May 19, 2020 at 10:37
I am using yarn if I delete my node modules should I simply run yarn install? – user12073145 Commented May 19, 2020 at 10:47
Yup. But before that try installing @babel/preset-env, as one of the answers suggest, which might would do the trick. – ABGR Commented May 19, 2020 at 10:50

You need to install @babel/preset-env instead of babel-preset-env.

I believe that most babel modules now live under the @babel org

Edit:

also IMHO the correct syntax for the babelrc file should be

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