python安装提示No module named setuptools,wget提示ERROR 403: SSL is required

 在下载安装一个python工具时提示报错No module named setuptools

[root@kermit supervisor-3.3.0]$ sudo python setup.py install
Traceback (most recent call last):
  File "setup.py", line 32, in <module>
    from setuptools import setup, find_packages
ImportError: No module named setuptools

     于是去下载setuptools工具，但遇到报错 ERROR 403: SSL is required.

[root@kermit ~]# wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
--2017-11-03 11:20:16--  http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz

    这时可能你会把它认为是要进行ssl证书检查的错误，可能会去尝试下面的命令，但发现仍然会报错。另外wget在安装的时候也有一项配置：./configure --with-ssl=openssl，这个配置会影响wget是否支持获取https的内容。

sudo wget --no-check-certificate http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz

    实际这个ERROR 403: SSL is required报错只是要求请求的URL一定要是https, 请求方自己没有做301转向处理。所以使用以下的命令即可。然后安装setuptools

sudo wget  https://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c11.tar.gz
tar -xvf setuptools-0.6c11.tar.gz
cd setuptools-0.6c11
sudo python setup.py build
sudo python setup.py install
.....
