问题背景
root 用户可以运行pip install mkdocs
但gitlab-runner 运行pip install mkdocs 则下列错误
pip install mkdocs
Traceback (most recent call last):
File "/bin/pip", line 7, in <module>
from pip._internal import main
ImportError: No module named 'pip._internal'经过排查，发现是gitlab-runner 在某些python path 的权限问题
解决方法
1. cat /bin/pip 查看使用的python 代码
#!/usr/bin/python3
# -*- coding: utf-8 -*-
import re
import sys
from pip._internal import main
if __name__ == '__main__':
sys.argv[0] = re.sub(r'(-script\.pyw?|\.exe)?$', '', sys.argv[0])
sys.exit(main())可知，使用的是python3
查看path 路径
切换到root 用户
然后在命令行运行：
[root@test75vm1 ~]# python3

>>> import sys
>>> sys.path
['', '/usr/lib64/python34.zip', '/usr/lib64/python3.4', '/usr/lib64/python3.4/plat-linux', '/usr/lib64/python3.4/lib-dynload', '/usr/lib64/python3.4/site-packages', '/usr/lib/python3.4/site-packages']check path 路径的权限
ls -rlt /usr/lib/python3.4/site-packages
修改python path 路径的权限
ls -rlt 发现有写目录是没有执行权限的。
执行命令
chmod 755 -R /usr/lib64/python3.4 /usr/lib64/python3.4/plat-linux /usr/lib64/python3.4/lib-dynload /usr/lib64/python3.4/site-packages /usr/lib/python3.4/site-packages
