ImportError：当我尝试通过 python pip 安装结构时，没有名为“pip._vendor.distlib.scripts”的模块

Question

当我在 CentOS4.9 上运行这个命令时，会发生这样的错误。我尝试在 Google 中搜索它，但没有找到。看来我是第一个遇到这种问题的人。

# pip 安装结构

Traceback (most recent call last):

ImportError: No module named 'pip._vendor.distlib.scripts'

我去了 /usr/local/lib/python2.7/site-packages/pip-7.0.1-py2.7.egg/pip/_vendor/distlib。有scripts.py文件。

按照here 的建议，尝试安装 SSL 支持。

在 CentOS 上：

yum install openssl openssl-devel

在 Debian 上：

apt-get -y install libssl-dev

如果libssl-dev 不存在，请尝试：openssl-dev。
