__dirname在带有Webpack捆绑的节点js中不起作用 [英] __dirname is not working in node js with webpack bundling

问题描述

我当前的目录是

D:\bkp\Programming\TestWorks\nodejs\testApp

但是当我使用 __ dirname 并尝试使用Express Server显示文件时，它给了我这个错误

but when i am using __dirname and trying to show a file with express server it gives me this error

Error: ENOENT: no such file or directory, stat 'D:\views\index.html'

我的代码是

res.sendFile(__dirname + 'views/index.html');

当我将其与webpack捆绑在一起并运行捆绑文件时，就会发生这种情况.否则，如果我只是运行普通的app.js文件，它将运行正常.帮助将不胜感激.

when i am bundling it with webpack and run the bundle file then this happens. Otherwise if i just run the normal app.js file it works fine. Help would be appreciated.

推荐答案

这是因为webpack可以以不同方式处理__dirname(和其他节点特定的事物).如果您希望它的行为像往常一样，请在您的webpack配置中使用它:

This is because webpack can handle __dirname (and other node specific things) in different ways. If you want it to behave like normal, use this in your webpack config:

{
    node: {
        __dirname: false
    }
}

请参阅: https://webpack.js.org/configuration/node/
