PIP Could not find any downloads that satisfy the requirement SQLAlchemy

问题:

• Ubuntu 12.04
• Apache 2.2.22

pip has stopped working on my ubuntu server and gives the below error when I try to download anything.

$ 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 

All of the below also do not work

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

My /etc/environment has the below settings which were working previously.

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

My /home/user/.pip

Has anyone got any idea what might be going wrong?

回答1:

You need to fetch pypi over HTTPS, not HTTP.

For some reason your pip is configured to retrieve from http://pypi.python.org/simple/ rather than https://pypi.python.org/simple/

回答2:

Answer: upgrade pip.

I had version 1.1 installed. With sudo pip install --upgrade pip I got version 8.1.2 and the package I wanted installed properly.

回答3:

You are not using https connections, which had been used since late 2013.

You may use --index options to correct index url. See http://pip.readthedocs.org/en/latest/reference/pip_wheel.html#index-url

回答4:

You can pass a specific index url with -i:

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

回答5:

Solution 1: Upgrade pip

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

then, you can use pip as:

sudo pip install SQLAlchemy 

Solution 2: Specific the index URL with -i

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

回答6:

Although it is old question, my solution may help someone.

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

This works for me.

回答7:

Why dont you try pip install in super user. Type su and your password, then try sudo pip install SQLAlchemy
