在Python 3.7虚拟环境中使用pip时出现错误“ Python中的ssl模块不可用”

Question

In a virtual environment activated in a virtual machine, I can't install any package with pip, since it raises a SSL related error.

I'm setting up a virtual environment (with virtualenv) to mimic the the settings of a server that I'm going to work with. So I installed mannualy (from tar file) a specific version of python (3.7.0) in a Ubuntu 18.04 virtual machine (using VirtualBox). Once my python version of choice was running I activated a virtual environment. The pip version is 18.1.

The problem comes when I try to install a python package, like:

$ pip install django

It raised this error:

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting django
Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/django/
Could not fetch URL https://pypi.org/simple/django/: There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/django/ (Caused by SSLError("Can't connect to HTTPS URL because the SSL module is not available.")) - skipping
Could not find a version that satisfies the requirement django (from versions: )
No matching distribution found for django

Neither of the answers that I found after searching helped me. Since pip can't install anything, it can't install packages like ssl nor OpenSSL. If anyone can help me, I thank a lot in advance.

Answer 1

I wasn't able to install pandas-datareader. I was getting the same error message. Then, in the CMD window, I just put the command "activate base" and then ran pip again and it worked. I tried with django before and after the "activate base" and if it didn't work before, it did work after. I think it's just some environment variables that are not configured properly. Luckily this will work for you as well. Have a nice day Rémy
