python - uwsgi 的构建轮失败

Question

我得到一个错误，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，但出现错误

    During handling of the above exception, another exception occurred:

我运行命令 sudo apt-get -y install python-dev，但发生了同样的错误。我真的不明白为什么会发生这些错误。我应该如何解决这个问题？为什么我被告知我需要在 uWSGI 中使用 C 编译器？应该如何处理我解决这个问题？

Answer 1

您的异常明确说明出了什么问题:

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页面。
