尝试运行我的 "webpack --config ./webpack.config.js" 时出错

Question

我正在尝试运行名为 Quill 的开源库的 webpack 配置，它使用 Webpack 作为它的捆绑器。当我运行命令 webpack --config ./_develop/webpack.config.js 时，配置尝试执行的每个 .js 文件都出现以下错误：

  if (env && env.coverage) {
    config.module.rules[4].use[0].options = {
      plugins: ['istanbul', 'transform-es2015-modules-commonjs']
    };
  }

  return config;
};

当然这都是开源的，而且我没有改变任何东西，所以这是按照他们在 Local Development 上的指示进行的全新安装。因此，我真的不太确定 webpack 的配置如何工作，我的配置文件有什么问题，以及我可以做些什么来改变它。

您的 webpack 中有一条规则告诉您使用加载器加载 js 文件。这个加载器是 'eslint-loader' 并且这个加载器用于检查你的 js 文件。这是这个加载器，它告诉您换行符不正确。有两种方法可以解决这个问题：

使用使用正确换行符的编辑器
删除或更改 .eslintc 中的规则

LF (\n) 是 Linux 中使用的换行符，而 windows (\r\n)

中使用的换行符是 CRLF

您也可以使用 "eslint --fix" 来尝试解决此问题

./node_modules/.bin/eslint --fix yourFileThatHaserrors

但是如果你使用转换换行符的编辑器，每次保存文件时都会发生这种情况。

总结一下：

你的配置文件不错
你的编辑器不是
