curl: (6) 无法解析主机：在 WSL 上

Question

我已经在 WSL 上安装了 Ubuntu 20.04 LTS。

我正在尝试运行以下命令：

curl https://developer.mozilla.org/en-US/docs/Web/API/WindowOrWorkerGlobalScope/fetch

失败并出现错误：

curl: (6) Could not resolve host: developer.mozilla.org

我试过其他方法，效果很好，例如

$ curl https://google.com
<HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8">
<TITLE>301 Moved</TITLE></HEAD><BODY>
<H1>301 Moved</H1>
The document has moved
<A HREF="https://www.google.com/">here</A>.
</BODY></HTML>

这里有一些细节：

$ nslookup developer.mozilla.org
Server:         127.0.0.1
Address:        127.0.0.1#53

请帮助理解问题。

Answer 1

这对我有用：https://github.com/microsoft/WSL/issues/4731#issuecomment-562935992

This is happening to me after my pc goes to sleep for long hours. Shutting down wsl2 (wsl.exe --shutdown) and open it again solves the problem until the next time the pc goes to sleep again for long hours.

Answer 2

对我来说，它发生在 Windows 11 升级之后。

我必须更新 /etc/wsl.conf 并重新启动我的 WSL 实例

[network]
generateResolvConf = true

curl: (6) 无法解析主机：在 WSL 上

curl: (6) Could not resolve host: on WSL
