对于公网服务器，我们常常需要在其上运行Python脚本，由于服务器操作系统上默认的Python版本不同，在运行过程中常出现报错，今天主要介绍关于“ImportError: No module named requests.packages.urllib3 ”报错的解决方法。
[root@104 ~]# python run620.py Traceback (most recent call last): File "run620.py", line 7, in <module> import json, requests File "/usr/lib/python2.6/site-packages/requests/__init__.py", line 58, in <module> from . import utils File "/usr/lib/python2.6/site-packages/requests/utils.py", line 32, in <module> from .exceptions import InvalidURL File "/usr/lib/python2.6/site-packages/requests/exceptions.py", line 10, in <module> from .packages.urllib3.exceptions import HTTPError as BaseHTTPError File "/usr/lib/python2.6/site-packages/requests/packages/__init__.py", line 99, in load_module raise ImportError("No module named '%s'" % (name,)) ImportError: No module named 'requests.packages.urllib3'在报错后，得知缺少’requests.packages.urllib3’ 库，尝试安装：
[root@104 ~]# pip install requests.packages.urllib3 DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python.

可以发现 pip Could not find a version that satisfies the requirement requests.packages.urllib3 ，这是由于requests 的版本需要为 2.6.0。
解决方法：
pip install --upgrade --force-reinstall 'requests==2.6.0' urllib3 [root@104 ~]# pip install --upgrade --force-reinstall 'requests==2.6.0' urllib3 DEPRECATION: Python 2.6 is no longer supported by the Python core team, please upgrade your Python.
