Still get "Cannot find module '@babel/core'" when running jest.
Could you please provide a simple package.json of a running example?
Hello!
First: Great job!
I'm trying to run jest with babel 7 and I use the library. I'm encountering following error:
FAIL src/tests/some.test.jsx
โ Test suite failed to run
ReferenceError: Unknown helper assertThisInitialized
at loadHelper (node_modules/babel-7-jest/node_modules/@babel/helpers/lib/index.js:239:40)
at ThisExpression (node_modules/@babel/plugin-transform-classes/lib/vanilla.js:51:60)
My babel config:
"babel": {
"plugins": [
"@babel/plugin-syntax-dynamic-import",
"@babel/plugin-proposal-class-properties"
],
"presets": [
[
"@babel/preset-env",
{

"browsers": [

"safari>=9",
"ie>=11"
]
},
"useBuiltIns": "usage",
"modules": false
}
],
"@babel/preset-stage-0",
"@babel/preset-react"
],
"env": {
"production": {
"only": [
"src"
],
"plugins": [
"babel-plugin-transform-react-remove-prop-types",

"plugins": [
"@babel/plugin-transform-modules-commonjs",
"babel-plugin-dynamic-import-node-babel-7",
"@babel/syntax-export-extensions"
]
}
}
},
Have no idea right now what is the problem. Any thoughts?
