Question

我被困住了。我需要任何帮助。

我的环境：WSL2

我执行webpack-dev-server

npm run dev

这是它的日志：

所以我尝试使用 sudo 更改权限文件，但我的权限被拒绝了。

我通过ls -al确认我有权限，但是此文件的权限显示为 -????????.

请问你能告诉我吗？

Answer 1

我遇到过类似的问题，对我有用的解决方案是从 HOME 在 WSL sub-directory 中克隆（或创建）我的存储库，而不是 ~/workspace/React Study已安装 C:\.

此解决方案甚至使用 VS 代码集成提高了很多性能，特别是在您编辑和保存文件时。

Answer 2

Windows 可能不喜欢您 storing/trying 在 C:/ 中写入文件这一事实。由于 WSL 并不总是与 Window 的权限系统正确绑定，即使使用 sudo WSL 也可能无法更改这些文件的权限。

我建议将目录更改到您知道您的用户拥有所有权的地方（例如您的文档库或 C:/users/yourusername），然后重试。
