npm 安装后如何防止 Webpack 错误？

Question

我正在做一个项目，一切都很顺利，直到我做到了npm install。

然后，Webpack 抛出如下错误：

new ForkCheckerPlugin(),
        ^
TypeError: ForkCheckerPlugin is not a constructor

我尝试将 Webpack 降级到 1.15.0 版，删除 node_modules 文件夹并重新安装，但我仍然遇到同样的错误。

出了什么问题？

更新：

以防万一，当我执行npm install 时，Webpack 模块显示为UNMET PEER DEPENDENCY webpack@3.4.1。

将 awesome-typescript-loader 降级到 2.2.4 时出现以下错误：

WebpackOptionsValidationError(webpackOptionsValidationErrors);
        ^
WebpackOptionsValidationError: Invalid configuration object. Webpack has been initialised using a configuration object that does not match the API schema.
 - configuration has an unknown property 'postcss'. These properties are valid:

   For typos: please correct them.
   For loader options: webpack 2 no longer allows custom properties in configuration.
     Loaders should be updated to allow passing options via loader options in module.rules.
     Until loaders are updated one can use the LoaderOptionsPlugin to pass these options to the loader:
     plugins: [
       new webpack.LoaderOptionsPlugin({
         // test: /\.xxx$/, // may apply this only for some modules
         options: {
           postcss: ...
         }
       })
     ]
 - configuration.module has an unknown property 'postLoaders'. These properties are valid:
   object { exprContextCritical?, exprContextRecursive?, exprContextRegExp?, exprContextRequest?, loaders?, noParse?, rules?, unknownContextCritical?, unknownContextRecursive?, unknownContextRegExp?, unknownContextRequest?, unsafeCache?, wrappedContextCritical?, wrappedContextRecursive?, wrappedContextRegExp?, strictExportPresence?, strictThisContextOnImports? }
   Options affecting the normal modules (`NormalModuleFactory`).
 - configuration.node should be one of these:
   false | object { Buffer?, __dirname?, __filename?, console?, global?, process?, ... }
   Include polyfills or mocks for various node stuff.
   Details:
    * configuration.node should be false
    * configuration.node.global should be a boolean.

似乎降级 webpack@2.1.0-beta.22 解决了我的问题。但是现在，我又遇到了一个错误：

/home/nsanz/Documentos/git/tachology/node_modules/extract-text-webpack-plugin/node_modules/async/dist/async.js:1003
        iteratee(coll[index], index, onlyOnce(iteratorCallback));
        ^
TypeError: chunk.sortModules is not a function

安装 extract-text-webpack-plugin@2.1.2 后，我收到这个新错误：

/home/nsanz/Documentos/git/tachology/node_modules/extract-text-webpack-plugin/index.js:187
        throw new Error("Breaking change: extract now only takes a single argument. Either an options " +
        ^
Error: Breaking change: extract now only takes a single argument. Either an options object *or* the loader(s).
Example: if your old code looked like this:
    ExtractTextPlugin.extract('style-loader', 'css-loader')

You would change it to:
    ExtractTextPlugin.extract({ fallback: 'style-loader', use: 'css-loader' })

The available options are:
    use: string | object | loader[]
    fallback: string | object | loader[]
    publicPath: string

修复另一个 ExtractTextPlugin 错误后，我收到一个新错误（我通过不同的 pug 文件找到了这个错误）：

ERROR in ./client/app/main/main.pug
Module parse failed: /home/nsanz/Documentos/git/tachology/node_modules/pug-html-loader/lib/index.js!/home/nsanz/Documentos/git/tachology/client/app/main/main.pug Unexpected token (1:0)
You may need an appropriate loader to handle this file type.

Answer 1

在您的 devDependencies 中，尝试降级：

awesome-typescript-loader": "3.2.1"

到这里：

awesome-typescript-loader": "2.2.4"

如果还是不行，我们再找其他解决办法。

在最后一个问题更新之后，这是我的建议。 删除webpack.make.json中的下一行：

 config.plugins = [
        /*...*/
        new ForkCheckerPlugin(), // <-- Delete this line

原因是 Webpack >= 3.0.0 似乎内置了 fork

似乎 Webpack 3.4.1 给你带来了麻烦，因为你依赖于一些旧的依赖项。执行以下操作：

npm uninstall webpack --save-dev

然后：

npm install webpack@2.1.0-beta.22 --save-dev

希望现在可以使用！ 如果还是不行，尝试重新合并new ForkCheckerPlugin() 语句（这次使用webpack 2.1.0）

它现在似乎可以与 webpack 2.1.0-beta.22 一起使用，但您遇到了另一个错误。

发生此错误是因为 extract-text-webpack-plugin 与 webpack 的主要版本不同（3.x.x 与 2.x.x）。这样做：

npm uninstall --save-dev extract-text-webpack-plugin

然后这个：

npm install --save-dev extract-text-webpack-plugin@2.1.2

这个新错误更容易解决。它在您的错误日志中进行了解释。在您的webpack.make.js 中更改行：

ExtractTextPlugin.extract('style', 'css!postcss')

收件人：

ExtractTextPlugin.extract({ fallback: 'style-loader', use: 'css-loader' })

事情变得有趣起来。我建议更改它（在webpack.make.js 内部）：

}, {
    // Pug HTML LOADER
    // Reference: https://github.com/willyelm/pug-html-loader
    // Allow loading Pug throw js
    test: /\.(jade|pug)$/,
    loaders: ['pug-html']
}, {

到这里：

}, {
    // Pug HTML LOADER
    // Reference: https://github.com/willyelm/pug-html-loader
    // Allow loading Pug throw js
    test: /\.(jade|pug)$/,
    loaders: ['pug-html-loader']
}, {
