npm - webpack-dev-server:npm 错误 Windows_NT 7601

Question

我在尝试命令时遇到以下错误:

$ npm run dev

我还使用过nodejs cmd、git，并且还拥有cmd的管理权限。

错误如下:

D:\IIT Samester\KAZ\ReactJSProjects\GitFrom\webpack-example-master\webpack-examp
le-master>npm run dev

> webpack-example@0.0.0 dev D:\IIT Samester\KAZ\ReactJSProjects\GitFrom\webpack-example-master\webpack-example-master

请帮忙解决问题。

Answer 1

是的，我已经自己解决了这个问题。

这是端口问题，没有别的问题。

我有其他程序可以在端口 8080 上运行。

webpack-dev-server 默认情况下也想使用该端口。

所以我刚刚将 ProjectFolder\node_modules\webpack-dev-server\bin\webpack 中的端口号从 8080 更改为 8081(可以是任何有效的其他值) -dev-server.js 文件。

另一个解决方案是您可以停止该程序在端口 8080 上运行。

谢谢:)
