Question

所以当我开始收到ReactMount不在React / lib / ReactMount的错误时，我试图将我的react-webpack应用程序放在Heroku上。然后我尝试了很多不同的东西，最后尝试使用相同的react-webpack generater创建一个新项目。现在我甚至在运行localhost时也会遇到同样的错误，这意味着它必须是由某个地方的更新引起的，对吧？

有人对此有所了解吗？

Answer 1

看起来你和我在同一条船上。我们都使用旧版本的react-hot-loader更新到版本3.x并执行另一个npm安装。

请参阅 - https://github.com/gaearon/react-hot-loader/issues/417

Answer 2

对我来说有用的是从反应中简单地改变：^ 15.0.0到15.3.1。

Answer 3

您需要更新react才能解决此问题。就我而言，我没有使用热装载机。响应升级解决了这个问题。目前位于15.4.0

Answer 4

转到node_modules / react-hot-loader / index.js并使用try catch而不是必需

替换此代码

prependText = [
'/* REACT HOT LOADER */',
'if (module.hot) {',
  '(function () {',
    'var ReactHotAPI = require(' + JSON.stringify(require.resolve('react-hot-api')) + '),',
        'RootInstanceProvider = require(' + JSON.stringify(require.resolve('./RootInstanceProvider')) + '),',
        'ReactMount = require("react/lib/ReactMount"),',
        'React = require("react");',

    'module.makeHot = module.hot.data ? module.hot.data.makeHot : ReactHotAPI(function () {',
      'return RootInstanceProvider.getRootInstances(ReactMount);',
    '}, React);',
  '})();',
'}',
'try {',
  '(function () {',
 ].join(' ');

使用try和catch来处理错误的新代码

var reactMountImport;
   try {
 require('react-dom/lib/ReactMount');
     reactMountImport = 'ReactMount = require("react-dom/lib/ReactMount"),';
  } catch(e) {
   console.log(e)
  reactMountImport = 'ReactMount = require("react/lib/ReactMount"),';
  }

 prependText = [
'/* REACT HOT LOADER */',
'if (module.hot) {',
  '(function () {',
    'var ReactHotAPI = require(' + JSON.stringify(require.resolve('react-hot-api')) + '),',
        'RootInstanceProvider = require(' + JSON.stringify(require.resolve('./RootInstanceProvider')) + '),',
        reactMountImport,
        'React = require("react");',

    'module.makeHot = module.hot.data ? module.hot.data.makeHot : ReactHotAPI(function () {',
      'return RootInstanceProvider.getRootInstances(ReactMount);',
    '}, React);',
  '})();',
'}',
'try {',
  '(function () {',
].join(' ');

您可以在此处查看更改 https://github.com/gaearon/react-hot-loader/pull/430/commits/4ff08252bd8bf90dbc89fc6d032f557825ec0300#diff-168726dbe96b3ce427e7fedce31bb0bc
