使用conda安装某个包,报错如下:

这里的问题主要出在 lsb_release 包上, 此处可通过修改conda中pip下的 distro.py , 编辑其初始化方法的 include_lsb属性为False.


stackoverflow - 解答:
I had the same problem on a shared hosting account
 which is very limiting (I was installing python and pip for my user only). 
Their lsb_release -a returns something non-standard 
and I cannot change it. 
I solved the issue by editing distro.py
 (in your case: /usr/local/lib/python2.7/dist-packages/pip/_vendor/distro.py) 
and changing the default parameter of __init__ method. 
In my version it was at the line 545. Snippet:

def __init__(self,
    include_lsb=True,
    os_release_file='',
    distro_release_file=''):
Just change include_lsb=True to include_lsb=False.

即:

def __init__(self,
                 include_lsb=False,
                 os_release_file='',
                 distro_release_file='',
                 include_uname=True):
