错误：捆绑失败：TypeError：无法读取未定义的属性“transformFile”

Question

每当我运行 react-native start 时都会收到此错误，但最近在我的节点模块中安装了 firebase-tools 和 stripe 后开始发生此错误，但在此之前它会运行得很好，这也是错误的堆栈跟踪：

::ffff:127.0.0.1 - - [22/Mar/2020:19:59:30 +0000] "GET /index.bundle?platform=android&dev=true&minify=false HTTP/1.1" 500 - "-" "okhttp/3.12.1"

error: bundling failed: TypeError: Cannot read property 'transformFile' of undefined

这是我的 package.json：

  "version": "0.0.1",

  "private": true,

  "scripts": {

    "android": "react-native run-android",

    "ios": "react-native run-ios",

    "start": "react-native start",

    "test": "jest",

    "lint": "eslint ."

  },

  },

很清楚另一个在 StackOverflow 上存在相同问题的问题，但该问题的解决方案对我不起作用，因为当我运行 react-native start 时 npm 忽略了它，因为这些模块已被弃用，我仍然得到相同错误

Answer 1

将 NodeJS 降级到 LTS 版本总是有帮助的。我在尝试使用 NodeJS^17 时遇到了同样的问题，但是当我将其降级到 NodeJS^14 并重新安装 node_modules 时，一切都已修复。

Answer 2

问题下第一条评论中的解决方案对我有用，它删除了 node_modules 和 package-lock.json，但是，我不想这样做，因为我知道我会遇到更多错误，而且我确实做到了，但是至少我能够修复它们并让它运行，这与我询问的顽固错误不同。所以是的，这种方法有效，但我绝对希望有人有更好的方法。

Answer 3

我遇到了这个错误。我做了两件事，我认为这导致我解决了这个问题：我在 monorepo 工作，所以我将以下代码添加到我的package.json："workspaces": {&nbsp; &nbsp; "nohoist": [&nbsp; &nbsp; &nbsp; &nbsp; "react-native",&nbsp; &nbsp; &nbsp; &nbsp; "react-native/**",&nbsp; &nbsp; &nbsp; &nbsp; "react",&nbsp; &nbsp; &nbsp; &nbsp; "react/**"&nbsp; &nbsp; ]}我将我的metro-react-native-babel-preset包从升级^0.58.0到最新版本 - ^0.59.0( yarn add -D metro-react-native-babel-preset)
