Cannot find module babel-preset-es2015

Question

For Babel version 6 the package name is babel-preset-es2015 and for Babel version 7 the package name is @babel/preset-es2015.

From the error it seems that you’re using version 7. The es20XX-presets are deprecated, so I recommend you switch to @babel/preset-env.

First install the preset (using npm):

npm install --save-dev @babel/preset-env

Then add the preset to your .babelrc

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