python/pip error on osx

问题:

I've recently purchased a new hard drive and installed a clean copy of OS X Mavericks. I installed python using homebrew and i need to create a python virtual environment. But when ever i try to run any command using pip, I get this error. I haven't been able to find a solution online for this problem. Any reference would be appreciated. Here is the error I'm getting.

If you need any extra information from me let me know, this is my first time posting a question here. Thanks.

回答1:

Ok I found out online that these errors are related to openssl. But i already had openssl installed. A little more research and I tried the following and it solved the issue for me. Here's my solution in case you get the same error.

brew install openssl brew link openssl --force brew uninstall python brew install python --with-brewed-openssl 

Hope that helps.

回答2:

The brew install openssl solution above did not work for with using Python 3. Then I realized that I had installed Python 3.4.2 but the "No HTTPSHandler" exception was looking in /usr/local/Cellar/python3/3.4.1/....

After deleting all older Python 3 paths and reinstalling virtualenv it works again:

pip3 uninstall virtualenv pip3 install virtualenv 

Note that install --upgrade didn't work, needs to be uninstalled first.

回答3:

Had the same error on 10.10 when trying to install pygame. Fixed it by brew remove python3 then installed python3.4.2 from python.org along with active state tcl.

Error gone then pip3 install virtualenv

You will get a message with brew doctor Warning: Python is installed at /Library/Frameworks/Python.framework

Homebrew only supports building against the System-provided Python or a brewed Python. In particular, Pythons installed to /Library can interfere with other software installs.

Which for me doesn't matter as I prefer to stick with python.org installs so python is the same across platforms rather than differing in brew (have run into problems before)

回答4:

I had to manually add library linking to make it works because I had error with brew link openssl --force

brew update     brew install openssl     ln -s /usr/local/opt/openssl/lib/libcrypto.1.0.0.dylib /usr/local/lib/     ln -s /usr/local/opt/openssl/lib/libssl.1.0.0.dylib /usr/local/lib/ brew uninstall python brew install python --with-brewed-openssl
