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出现以下错误。

$ 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

以下所有内容也不起作用

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

我的/etc/environment具有以前设置的以下设置。

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

我的/home/user/.pip

有谁知道可能出现什么问题？

Answer 1

答案：升级点。

我安装了1.1版。使用sudo pip install --upgrade pip我得到了版本8.1.2并且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，您的点子已配置为从http://pypi.python.org/simple/而不是https://pypi.python.org/simple/

进行检索

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选项来更正索引网址。 见http://pip.readthedocs.org/en/latest/reference/pip_wheel.html#index-url

Answer 4

您可以使用-i传递特定的索引网址：

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

然后，您可以将pip用作：

sudo pip install SQLAlchemy

解决方案2：使用-i

指定索引网址

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

Answer 6

虽然这是一个老问题，但我的解决方案可能对某人有帮助。

pip install SQLAlchemy --extra-index-url=https://pypi.python.org/simple/

这适合我。

Answer 7

为什么不尝试在超级用户中使用pip install。输入su和您的密码，然后尝试sudo pip install SQLAlchemy
