：找不到模块“React error-overlay/中间件”

Question

这很令人沮丧。从昨天早上开始，我就一直在处理这个问题。我有一个反应申请，我已经有一年多没有启动了。上次我启动这个应用程序时运行得很好。但是，我想在本地处理它，并且在一年前运行良好时使用完全相同的package.json，但在浏览器中失败，错误消息如下：

TypeError: Cannot read property 'ReactCurrentOwner' of undefined

由于package.json有一年的历史，今天我运行npm更新，当我尝试运行该程序时，会收到以下错误：

Error: Cannot find module 'react-error-overlay/middleware'

为什么？

Answer 1

因此，您所遇到的是npm模块的工作方式--这个问题并不是react独有的。我们不能指望你解决这个问题--但我可以为你指明正确的方向。

我将使用package.json中的依赖项作为示例，行：

"react-error-overlay": "^1.0.10"在版本号旁边有一个插入符号(^)。

这意味着在大多数情况下，当您运行npm install或npm update时，npm将获取该包的最新的版本，高于该版本号。

如果您在文章中比较这两个不同的package.json文件，您会注意到对于相当多的依赖项，有多个主要的包版本被跳过。如果您查找语义版本控制，您会发现一个主要的版本凸起通常是由于模块中的中断更改所致。

例如：

老："react-error-overlay": "^1.0.10"

新："react-error-overlay": "^5.1.3"

在这里，您将从主要版本1.x.x跳到5.x.x。这是超过4个打破的变化，只是这个模块。

基本上，这意味着模块的工作方式与以前不同。如果您的项目在大约一年前就开始工作了--并且运行了npm update --那么现在它很可能会失败，因为您正在引入新的主要包版本。

如果您只希望您的项目像以前一样工作，下面是我的建议：

取package.json的原始版本，并删除版本号中的^插入符号。

然后清除项目中的node_modules文件夹。

然后运行npm install。

这应该会使模块版本与您之前的工作非常相似。那就试试看它是否运行。如果是这样的话，从那里单独更新您的依赖项--并找出哪些主要版本的颠簸会导致项目崩溃。

还：

至于您正在获得的typeError，它源于react-konva，正如在这个发布线程中所指出的：

https://github.com/konvajs/react-konva/issues/147#issuecomment-346217504

react-konva以上版本1.1.6适用于react v16及以上版本

通过使用以下版本来实现目标react v15：

"react-konva": "1.1.6"
