问题描述

Linux下使用python开发,需要uwsgi模块时,常常会出现pip install 失败的情况,就像下图这样。是什么原因造成的呢?因为缺少一个python-devel包,所以只需要下载安装这个包就可以解决了。但是要特别注意python版本要与之对应的问题。

解决办法

从yum源上下载安装对应python版本的python-devel,如果不清楚的话先用 python --version 命令查看python版本,然后yum search python3,Tab键搜索出来下载。

[root@VM_0_13_centos ~]# yum install python36u-devel
Loaded plugins: fastestmirror, langpacks

Complete!

Python-dev是个啥?

linux发行版通常会把类库的头文件和相关的pkg-config分拆成一个单独的xxx-dev(el)包.以下情况需要python-dev包:

  1. 安装一个源外的python类库, 而这个类库内含需要编译的调用python api的c/c++文件;
  2. 自己写的一个程序编译需要链接libpythonXX.(a|so)
    (不含使用ctypes/ffi或者裸dlsym方式直接调用libpython.so)
    其他正常使用python或者通过安装源内的python类库的不需要python-dev.
