无法解决 fbjs/lib/memoizeStringOnly

Question

刚刚刷新了我的电脑，但现在我遇到了问题运行我的代码....

当运行 "npm start" 我得到以下错误：

> ERROR in ./~/react-dom/lib/CSSPropertyOperations.js Module not found:
> Error: Can't resolve 'fbjs/lib/memoi zeStringOnly' in
> 'C:\Code\Project.Web\node_modules\react-dom\lib'
> @ ./~/react-dom/lib/CSSPropertyOperations.js 20:24-61  
> @ ./~/react-dom/lib/ReactDOMComponent.js  @

> ./~/react-dom/lib/ReactDOM.js  @ ./~/react-dom/index.js  @
> ./source/components/index.js  @ multi
> (webpack)-dev-server/client?http://0.0.0.0:30 00
> webpack/hot/dev-server ./index.js

我尝试更新所有包但遇到同样的错误...

这是我的 package.json 文件：

好的，经过大量谷歌搜索后，我找到了解决方法。我仍然不确定为什么会出现此错误。

但是根据这个有办法在webpack中添加alias

所以我把这个添加到我的 webpack.config.js

var alias = {};
alias['fbjs/lib/memoizeStringOnly'] = '../node_modules/fbjs/lib/memoizeStringOnly';
module.exports = {
  .
  .
  alias : alias,
  .
  .
}

现在可以使用了！

但是，现在我猜，一定是某些包被破坏了，试图从错误的位置访问这个组件

在过去一周左右的时间里，我运行遇到了同样的问题，但 react-dom@15.4.2 而不是 react-dom@15.5.4。我认为我发现的问题是 Webpack 无法解析 react-dom/node_modules 目录中的 fbjs 依赖项。

对我来说，我能够通过将 fbjs 包作为显式依赖项包含在 package.json 中来解决问题。现在，react-dom 中的模块不再链接到 react-dom 的对等项，而是链接到项目级模块。

现在，我认为这不一定是正确的解决方案，特别是如果您允许在 package.json 中使用“~”和“^”进行小版本更新，但因为我们只是更新我们的依赖项当我们需要手动操作时，我们的团队很乐意指定 fbjs 的版本。

我们的片段package.json：

"dependencies": {
    "assets-webpack-plugin": "3.5.1", 
    "babel-core": "6.24.0",
    "babel-loader": "6.4.1",

我运行在卸载软件包后也出现此错误。似乎 fbjs 也以某种方式被删除了，尽管其他软件包仍然依赖于它。

我通过 npm install fbjs --save

手动安装 fbjs 修复了它
