Question

我当时正在使用react@15.6.2但是正在尝试更新到16.2.0

我删除了node_modules文件夹，然后执行npm cache clean和npm install

但是，控制台会一直显示此消息

UNMET PEER DEPENDENCY react@15.6.2 invalid

在我运行webpack服务器之后，浏览器只会抛出一条错误消息：

Cannot read property 'ReactCurrentOwner' of undefined

为什么会发生？

这是我的package.json的样子：

  "devDependencies": {
    "autoprefixer": "^6.3.6",
    "babel-core": "^6.8.0",
    "babel-loader": "^6.2.4",

我刚解决了这个问题。

让我感到困扰的是，即使您删除了node_modules文件夹，包版本也保持不变（旧版本）。我仍然不知道为什么

因为react的错误消息表明：我react-dom和npm ls react都卸载了{ npm ERR! peer dep missing: react@^16.0.0, required by react-dom@16.2.0

执行npm install react@16.2.0和npm install react-dom@16.2.0重新安装后，浏览器的错误消息消失了！：）

React 16.2.0显示错误“无法读取未定义的属性'ReactCurrentOwner'”
