React 16.2.0显示错误"Cannot read property 'ReactCurrentOwner‘of undefined“
React 16.2.0显示错误"Cannot read property 'ReactCurrentOwner‘of undefined“
提问于 2018-04-22 22:00:39
我使用的是react@15.6.2，但正在尝试更新到16.2.0
我删除了node_modules文件夹，然后执行npm cache clean和npm install
但是，控制台仍会显示此消息
UNMET PEER DEPENDENCY react@15.6.2 invalid
在我运行了我的webpack服务器之后，浏览器就抛出了一条错误消息：
Cannot read property 'ReactCurrentOwner' of undefined
为什么会发生这种情况？
下面是我的package.json的样子：

我刚刚解决了这个问题。
令我困扰的是，即使您删除了node_modules文件夹，包的版本仍然保持不变(旧版本)。我还是不知道为什么
因此，我卸载了react和react-dom，因为npm ls react的错误消息表明：npm ERR! peer dep missing: react@^16.0.0, required by react-dom@16.2.0
通过执行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！:)
