使用 webpack 和 babel-loader 编译时出错

Question

我似乎无法使用 babel 6 加载器和 webpack 进行编译。它快把我逼疯了。有没有其他人遇到过这个问题？我一辈子都看不到我在哪里搞砸了。 :)

Answer 1

根据错误，redux 似乎在抱怨stage 选项。这可能是因为redux 仍在使用 Babel 5。这个来自 Babel 6 的stage option has been removed。

模块构建失败：ReferenceError: [BABEL] /Users/montague/Sites/redux/routing/node_modules/redux/lib/index.js： 未知选项： /Users/montague/Sites/redux/routing/node_modules/redux/.babelrc.stage

但是您不应该通过 babel 运行这些文件。因此，您的 webpack.config.js 中的某些内容应该是错误的。可能是因为您的exclude 字段有一个额外的s。

变化：

excludes: /(node_modules|bower_components)/,
       ^

与：

exclude: /(node_modules|bower_components)/,

Answer 2

尝试创建一个没有 stage 属性的 .babelrc 文件（根）。如果您不需要设置任何属性，则可以只创建一个空括号。

{}

Answer 3

尝试先安装预设，因为babel6 默认情况下不会转换任何内容，但需要预设来定义其转换。

npm install --save-dev babel-preset-es2015

对于反应：

npm install --save-dev babel-preset-react

现在将预设添加到.babelrc 文件中：

{
  "presets": ["es2015"]
}

这应该可以解决问题，这正是我必须做的来解决这个问题。

Answer 4

忘记我在哪里看到的（让我知道是不是你，所以我可以给予信任）但是这个命令帮助我修复了许多 babel 引用错误。

rm $( find node_modules -name .babelrc)

Answer 5

如果您从加载器中排除 node_modules，那么您将如何处理使用 es6 编码的节点模块？
