【英文标题】：Which babel plugin is declaring this var?

【问题描述】：

我正在尝试启动auth0-lock 这个electron project。

在 auth0 的嵌套依赖项之一 (node-formidable) 中，文件顶部有这一行：

if (global.GENTLY) require = GENTLY.hijack(require);

这是他们用来测试覆盖全局要求的东西，但是将global.GENTLY 设置为 false 应该绕过它进入开发模式。

然而，这个项目的 webpack/babel 配置（如下）中的某些东西正在将这一行更改为：

var require;if (global.GENTLY) require = GENTLY.hijack(require);

这将覆盖全局 require 并使用 require is not a function 破坏文件/构建的其余部分

我正在逐一浏览插件以查找正在执行此操作的内容，但到目前为止什么也没做。

有人知道什么设置会导致这种覆盖吗？

【参考方案1】：

我遇到了同样的问题，通过将此插件添加到我的 webpack 配置（webpack v4）中解决了它：

new webpack.DefinePlugin( 'global.GENTLY': false )

希望他们很快会发布带有修复程序的强大@2。
