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
我的/etc/environment
具有以下设置,以前工作。
http_proxy="http://myproxyhere:portnumberhere/"
HTTP_PROXY="http://myproxyhere:portnumberhere/"

有谁知道可能出了什么问题?
最佳解决方法
您需要通过HTTPS获取pypi,而不是HTTP。
由于某种原因,您的pip配置为从http://pypi.python.org/simple/而不是https://pypi.python.org/simple/检索
次佳解决方法
答:升级点。
我安装了1.1版。使用sudo pip install --upgrade pip
,我得到了8.1.2版,我想要正确安装的软件包。
第三种解决方法
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。请参阅http://pip.readthedocs.org/en/latest/reference/pip_wheel.html#index-url
第四种方法
您可以使用-i
传递特定的索引URL:
sudo pip install SQLAlchemy -i https://pypi.python.org/simple
第五种方法
解决方案1:升级pip
sudo pip install --upgrade pip -i https://pypi.python.org/simple
那么,您可以使用pip
作为:
sudo pip install SQLAlchemy
解决方案2:使用-i
指定索引URL
sudo pip install SQLAlchemy -i https://pypi.python.org/simple
第六种方法
虽然这是一个老问题,但我的解决方案可以帮助某人。
pip install SQLAlchemy --extra-index-url=https://pypi.python.org/simple/
这适合我。
