pip已停止在我的ubuntu服务器上运行,并在我尝试下载任何内容时给出以下错误.

$ sudo pip install SQLAlchemy
Downloading/unpacking SQLAlchemy
  Cannot fetch index base URL http://pypi.python.org/simple/
  Could not find any downloads that satisfy the requirement SQLAlchemy
No distributions at all found for SQLAlchemy
Storing complete log in /home/user/.pip/pip.log

以下所有也不起作用

$ sudo pip install --upgrade pip 
$ sudo apt-get install build-essential

我/etc/environment有以下设置,以前工作.

http_proxy="http://myproxyhere:portnumberhere/"
HTTP_PROXY="http://myproxyhere:portnumberhere/"

我的 /home/user/.pip
