当我使用pip install时，在wsl中建立新连接失败

Question

我想在Windows 11的ubuntu子系统(WSL)的虚拟环境中安装flask-sqlalchemy，使用以下命令:

pip install flask-sqlalchemy

但是我在控制台窗口收到一个错误。

WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'NewConnectionError('<pip._vendor.urllib3.connection.HTTPSConnection object at 0x7ff5c27dff10>: Failed to establish a new connection: [Errno -3] Temporary failure in name resolution')': /simple/flask-sqlalchemy/

我认为这与我的Ubuntu子系统的网络连接有关。我尝试独立的Linux系统，它似乎是工作。我该如何解决这个问题?

Answer 1

我的问题终于解决了。我张贴以下步骤来解决这个问题。我检查了我的防火墙设置。这不是问题。我不使用代理，所以我跳过了代理问题。

i从控制台窗口检查ping

ping google.com

显示

ping: google.com: Temporary failure in name resolution

我找到了解决办法。似乎我的DNS服务器找不到与我传递的URL相关的地址。我得到了错误，因为resolv.conf文件没有在我的Ubuntu子系统中设置。

解决方案:

在wsl中的Ubuntu Linux类型命令

sudo nano /etc/resolv.conf

添加名称服务器并保存文件

nameserver 8.8.8.8
