构建uwsgi时出现错误

pythonubuntuuwsgi

我遇到一个错误，uwsgi的构建失败。 我的环境是Ubuntu，现在我想要安装uwsgi，所以我运行命令pip install uwsgi，但是出现了错误。

我运行了sudo apt-get -y install python-dev命令，但是同样的错误仍然存在。我真的不明白为什么会发生这些错误。我该如何解决？为什么uWSGI告诉我需要C编译器？我该如何解决？

您的异常明确指出了问题所在：

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

总的来说，您的系统没有安装C编译器（例如gcc）。尝试安装它。在Ubuntu中，可以使用sudo apt-get install gcc命令进行安装。

另外，我认为这个问题更适合在askubuntu页面提问。

这是因为服务器上没有C编译器。如果您正在使用像AWS或Digital Ocean这样的云实例，gcc通常未安装。因此，您需要手动安装它。

sudo apt update
sudo apt install gcc 
sudo pip install uwsgi # Sudo as the server requires root access

应该解决这个问题。

永远不要在使用sudo命令时使用pip。这样会破坏权限。你可能之前使用过sudo pip，现在包文件夹中的权限已经混乱了，因此你被迫一直使用sudo命令。 - MuhsinFatih

大多数Linux软件包管理器都提供预编译的软件。例如，在Ubuntu上：

最初的回答：

sudo apt install uwsgi-plugin-python3

这将使uwsgi全局可用，不仅限于一个虚拟环境中，并且是安装C编译器的替代方法。翻译成：这样可以让uwsgi在全局范围内使用，而不仅仅是在一个虚拟环境中，也是一种避免安装C编译器的选择。

嗯，当你使用“env python”时，这不是一个好主意！！！ - Cornea Valentin

这个命令对我有用：sudo apt install build-essential python3-dev
