记一次pip/pip3安装uwsgi报错

时间：2023-02-02 16:04:45

背景

本来是想着在centos 7.9的主机上面部署一个flask应用，采用的方式是linux+nginx+uwsgi来进行发布，其他的都没有问题，但是在使用pip安装uwsgi时报错了，安装不成功，查了很多方法：试过把pip更新、安装python3-devel等等，但都是不行，最后还是得靠自己，研究了下pip安装方式，发现安装uwsgi是编译安装的，最后一查询发现gcc-c++没有装，安装之后再去安装uwsgi发现就成功。

问题描述

下面是我安装的时候的报错： [root@* ~]# sudo pip3 install uwsgi WARNING: Running pip install with root privileges is generally not a good idea. Try pip3 install --user instead. Collecting uwsgi Using cached https://files.pythonhosted.org/packages/b3/8e/b4fb9f793745afd6afcc0d2443d5626132e5d3540de98f28a8b8f5c753f9/uwsgi-2.0.21.tar.gz Installing collected packages: uwsgi Running setup.py install for uwsgi ... error Complete output from command /usr/bin/python3 -u -c "import setuptools, tokenize;file='/tmp/pip-build-8796okps/uwsgi/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-2_lro4bs-record/install-record.txt --single-version-externally-managed --compile: /usr/lib64/python3.6/distutils/dist.py:261: UserWarning: Unknown distribution option: 'descriptions' warnings.warn(msg) running install using profile: buildconf/default.ini detected include path: ['/usr/include', '/usr/local/include'] Traceback (most recent call last): File "/tmp/pip-build-8796okps/uwsgi/uwsgiconfig.py", line 750, in init gcc_version_components = gcc_version.split('.')

During handling of the above exception, another exception occurred:

----------------------------------------

Command "/usr/bin/python3 -u -c "import setuptools, tokenize;file='/tmp/pip-build-8796okps/uwsgi/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-2_lro4bs-record/install-record.txt --single-version-externally-managed --compile" failed with error code 1 in /tmp/pip-build-8796okps/uwsgi/

解决方案

[root@* ~]# yum -y install python3-devel [root@* ~]# yum -y installl gcc-c++ 安装好之后再pip安装uwsgi就没问题了。
