uwsgi 的构建轮失败
Failed building wheel for uwsgi
我收到一个错误，为 uwsgi 构建轮子失败。
我的环境是Ubuntu，现在我想安装uwsgi，所以我运行命令pip install uwsgi。但是出现错误

我运行命令sudo apt-get -y install python-dev，但同样的错误happens.I真的无法理解为什么这些错误happens.How我应该修复这个？为什么我被告知我需要在 uWSGI 中使用 C 编译器？我应该如何解决这个问题？
您的异常明确说明了错误所在：
gcc_version_components = gcc_version.split('.')
AttributeError: 'NoneType' object has no attribute 'split'
和
raise Exception("you need a C compiler to build uWSGI")
Exception: you need a C compiler to build uWSGI
所以通常您的系统没有安装 c 编译器（例如 gcc）。尝试安装它。在 Ubuntu 中它将是 sudo apt-get install gcc.
顺便说一句。我认为这个问题更适合 askubuntu 页。
大多数 linux 包管理器提供大多数预编译的东西。例如 Ubuntu:
sudo apt install uwsgi-plugin-python3
这将使 uwsgi 全局可用，而不仅仅是在那个 virtualenv 中，并且是安装 C 编译器的一种替代方法。
这是因为服务器上没有C编译器。如果您使用云上的实例，例如 AWS 或 Digital Ocean gcc，通常不会安装。所以需要手动安装
sudo apt update
sudo apt install gcc
sudo pip install uwsgi # Sudo as the server requires root access
应该可以解决问题
