PIP无法找到满足SQLAlchemy要求的任何下载

Question

• Ubuntu 12.04
• Apache 2.2.22

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

有谁知道可能出了什么问题？

Answer 1

答:升级点.

我安装了1.1版.随着sudo pip install --upgrade pip我得到版本8.1.2和我想要正确安装的软件包.

Answer 2

您需要通过HTTPS获取pypi,而不是HTTP.

出于某种原因,您的pip配置为从http://pypi.python.org/simple/而不是https://pypi.python.org/simple/检索

Answer 3

您没有使用自2013年底以来一直使用的https连接.

您可以使用--index选项来更正索引URL.见http://pip.readthedocs.org/en/latest/reference/pip_wheel.html#index-url

Answer 4

您可以通过以下方式传递特定的索引网址-i:

sudo pip install SQLAlchemy -i https://pypi.python.org/simple

Answer 5

解决方案1:升级 pip

sudo pip install --upgrade pip -i https://pypi.python.org/simple

那么,你可以pip用作:

sudo pip install SQLAlchemy

解决方案2:使用特定索引URL -i

sudo pip install SQLAlchemy -i https://pypi.python.org/simple
