After npm run eject (this was needed in order to change the webpack.config), I've run into the following problem during the app compilation: Cannot find module 'babel-plugin-transform-decorators-legacy'.
I've tried multiple variants that are described here: Cannot find module '@babel/plugin-transform-react-jsx-source' when running React App
(one of the most popular was to delete node modules and do yarn install again - it didn't help)
What could be done to fix that issue?
Here is my .babelrc file:
{
"presets": [
[
"es2015",
{
"modules": false
}
],
"react",
"stage-2",
"react-app",
"babel-preset-expo"
],
"plugins": [
"syntax-dynamic-import",
"transform-decorators-legacy",
"transform-object-rest-spread",
"react-hot-loader/babel"
],
"env": {
"test": {
"plugins": [
"transform-decorators-legacy",
"transform-object-rest-spread",
"istanbul"
]
}
}
}
And my package.json:

UPDATE
I've also done yarn add babel-plugin-transform-decorators-legacy - it didn't work.
You are using @babel v7 but babel-plugin-transform-decorators-legacy is a plugin for babel 6.
You should use @babel/plugin-proposal-decorators.
More info at https://www.npmjs.com/package/babel-plugin-transform-decorators-legacy
(...)
"plugins": [
"syntax-dynamic-import",
["@babel/plugin-proposal-decorators", { "legacy": true }],
"@babel/plugin-proposal-object-rest-spread",
"react-hot-loader/babel"
]
(...)
and
npm i @babel/plugin-proposal-object-rest-spread @babel/plugin-proposal-decorators
