在尝试使用Webpack4和Babel7构建反应应用程序时,我遇到了以下错误.

./src/index.js中的错误模块构建失败(来自./node_modules/babel-loader/lib/index.js):错误:无法从'/ Users/me/Desktop /找到模块'babel-preset-react' reflask' - 如果你想解决"反应",请使用"module:react" - 你的意思是"@ babel/react"吗？at function.module.exports [as sync](/Users/me/Desktop/reflask/node_modules/resolve/lib/sync.js:43:15)at resolveStandardizedName(/ Users/me/Desktop/reflask/node_modules/@ babel /core/lib/config/files/plugins.js:101:31)在resolvePreset(/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/files/plugins.js:58:10) at createPreset(/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/files/plugins.js:77:20)at createDescriptor(/ Users/me/Desktop/reflask/node_modules/@ babel/core/lib/config/config-descriptors.js:154:9)items.map(/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:109:50 )在createPresetDescriptors(/ Users/me/Desktop /)的createDescriptors(/Users/me/Desktop/reflask/node_modules/@babel/core/lib/config/config-descriptors.js:109:29)的Array.map()处reflask/node_modules/@babel/core/lib/config/config-descriptors.js:101:10)在passPerPreset(/ Users/me/Desktop/reflask/node_modules/@ babel/core/lib/config/config-descriptors.

我已尝试删除node_modules文件夹并使用以下内容重新安装依赖项.

终奌站

rm -rf node_modules/
npm install

组态

的package.json

{
  "name": "reflask",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "start": "webpack-dev-server --open --mode development",
    "build": "webpack"
  },
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "@babel/core": "^7.1.0",
    "@babel/preset-env": "^7.1.0",
    "@babel/preset-react": "^7.0.0",
    "babel-loader": "^8.0.2",
    "html-loader": "^0.5.5", …

我刚刚将React Native从0.55更新为0.56.

但是,当我尝试运行代码(react-native run-android OR run-ios)时,捆绑停止到这一点:

Loading dependency graph, done.
error: bundling failed: TypeError: Cannot read property 'filename' of undefined
    at PluginPass.JSXOpeningElement ({path_to_my_project}/react-native/node_modules/babel-plugin-transform-react-jsx-source/lib/index.js:32:39) 

这是我的.babelrc:

{
  "presets": [
    "react-native"
  ],
  "env": {
    "development": {
      "plugins": [
        "transform-react-jsx-source"
      ]
    }
  }
}

和package.json

"dependencies": {
    "babel-jest": "23.4.2",
    "babel-preset-react-native": "5.0.2",
    "react": "16.4.1",
    "react-native": "0.56.0",
  }

我已经删除了node_modules文件夹并再次安装了包,但没有运气.

有什么建议吗？任何帮助,将不胜感激!
