我在运行JEST时遇到了通天塔问题。这是我的.babelrc：
{
"presets": [
"es2015", "react"
],
"plugins": [
["babel-plugin-root-import", {
"rootPathSuffix": "src"
}],
"transform-object-rest-spread",
"transform-class-properties",
"syntax-dynamic-import"
]
}
然后，当我运行yarn test时，出现此错误：
Plugin/Preset files are not allowed to export objects, only functions. In /Users/blah/blah
node_modules/babel-preset-es2015/lib/index.js
我对Package.json的开发依赖项是
"devDependencies": {
"@babel/core": "^7.4.5",
"@babel/preset-env": "^7.4.5",
"@babel/preset-react": "^7.0.0",
"babel-core": "^6.26.0",

我尝试将babel-preset-es2015更改为babel-preset-env，但是存在相同的问题。
