python - 在带 wifi 的公寓中安装 python 包时出错

Question

在 Windows 10 中，我安装了 linux 子系统。

在 cmd 中，我运行 bash。

在庆典中，

• 我发现我目前的 Python 是 2.7.6。
• 我想安装 regex python 库。但是下面有错误，请问有大佬知道怎么解决吗？

谢谢。

Answer 1

此错误消息表明您缺少 Python 开发库。

Python2/_regex.c:46:20: fatal error: Python.h: No such file or directory

您可以使用以下命令安装它们。

适用于 Linux/Debian/Ubuntu 的 Windows 子系统

sudo apt-get install python-dev

Fedora/RedHat/CentOS

sudo yum install python-devel
