我有一个使用 webpack 压缩/编译的 angular2 项目。

我将 tslink 加载器与 webpack 一起使用,因此我在webpack.config.js.

module.exports = {
...
tslint: {
    configuration: {
        rules: {
            quotemark: [true, "double"]
        }
    },

    // tslint errors are displayed by default as warnings
    // set emitErrors to true to display them as errors
    emitErrors: false,

    // tslint does not interrupt the compilation by default
    // if you want any file with tslint errors to fail
    // set failOnHint to true
    failOnHint: true,

    // name of your formatter (optional)
    formatter: "",

    // path to directory containing formatter (optional)
    formattersDirectory: "node_modules/tslint-loader/formatters/",

    // These options are useful if you want to save output to files
    // for your continuous integration server
    fileOutput: {
        // The directory where each file"s report is saved
        dir: "./webpack-log/",

        // The extension to use for each report"s filename. Defaults to "txt"
        ext: "xml",

        // If true, all files are removed from the report directory at the beginning of run
        clean: true,

        // A string to include at the top of every report file.
        // Useful for some report formats.
        header: "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<checkstyle version=\"5.7\">",

        // A string to include at the bottom of every report file.
        // Useful for some report formats.
        footer: "</checkstyle>"
    }
},
...
preLoaders: [
        {
            test: /\.ts$/,
            loader: "tslint"
        }
    ],
}
}

我将 webpack 1.13.1 更新为 2.1.0-beta.25 并且 tslint 配置打破了npm run build.

我将preLoaders指令更改为loaders

module: {
        ....
        {
            test: /\.ts$/,
            loader: 'tslint',
            exclude: /(node_modules)/,
            enforce: 'pre'
        },
    ],
}

这还不够,因为我仍然收到错误

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.

所以我应该移动 tslint 配置并将其放在其他地方。有点迷失在这里。因此,我们将不胜感激有关该问题的任何信息。

谢谢!

对于其他对 webpack 2 中的预加载器有问题的人。在 beta v2.1-beta.23 中,pre/postLoaders 发生了重大变化。

首先,“loaders”部分应重命名为“rules”。现在还根据规则定义了 pre/postLoaders。

在我的情况下,我使用 tslint 作为预加载器。要将 pre/postLoader 添加到规则中,请添加enforce值为pre或的属性post

module: {
    rules: [
        {
            enforce: 'pre',
            test: /\.tsx?$/,
            loader: 'tslint',
            exclude: /(node_modules)/,
        },
        {
            test: /\.tsx?$/,
            loaders: ['awesome-typescript-loader'],
            exclude: /(node_modules)/
        }
    ]
}

更多信息在 github 上发布:Webpack v2.1.0-beta.23

在发布信息中还有一个指向拉取请求的链接,该链接显示了 webpack 配置文件中所需的v2.1.0-beta.22更改v2.1.0-beta.23 。在那里你可以看到你还需要 LoaderOptionsPlugin。

plugins: [
    new webpack.LoaderOptionsPlugin({
        options: {
            tslint: {
                emitErrors: true,
                failOnHint: true
            }
        }
    })
]

好的..所以我只需要将tslint定义移到:

plugins: [
    new LoaderOptionsPlugin({
        options: {
           tslint: {
             ...

并宣布

const LoaderOptionsPlugin = require("webpack/lib/LoaderOptionsPlugin");

如果您不想添加插件,可以执行以下操作,

module: {
  rules: [
    {
      enforce: 'pre',
      test: /\.ts$/,
      loader: 'tslint-loader?' + JSON.stringify({
        emitErrors: true,
        failOnHint: true
      })
    }
  ]
}
