Installed Python3.7 from package, trying to run pip3.7 does not work - JBristow1729 - Jul-31-2019
Hi all.
I am working on an ubuntu 16.04 VM and have installed python3.7 from a package. I now have the following outputs when checking versions:
$ python --version
Python 2.7.12
$ python3 --version
Python 3.5.2
$ python3.7 --version
Python 3.7.4
Now I am trying to install packages using 'pip' - specifically the 'slackclient' package. I have successfully installed it using pip and pip3, but these packages doesn't correspond with python3.7, so trying pip3.7 gives me the following error:
$ pip3.7 install --user slackclient
pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting slackclient

I even tried running:
$ python3.7 -m pip install --user slackclient
to the save effect. What might be causing this and how do I resolve it?

what does pip -V show?
and pip3 -V

$ pip -V
pip 19.2.1 from /home/<user>/.local/lib/python3.5/site-packages/pip (python 3.5)
$ pip3 -V
pip 19.2.1 from /home/<user>/.local/lib/python3.5/site-packages/pip (python 3.5)
$ pip3.7 -V
pip 19.0.3 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)

What method did you use to install python3.7?
Are you using some sort of proxy at all? Check your network, firewalls, proxies, and so on.
You could also try upgrading you pip as it is older than the other two as it is 19.0.3 while the others are 19.2.1
sudo pip3.7 install --upgrade pip

I have a video on how to install Python on YouTube[1]. I also have a blog post[2] on my website. The basic steps are
sudo apt-get update
Now that the package lists have been updated we can upgrade to the latest versions with the apt-get upgrade command:
sudo apt-get -y upgrade
Once the packages have been upgraded, we can install Python 3.7. This is done with the apt-get install command:
sudo apt-get install -y python3.7
Once the installation is complete, we confirm that it was successful by calling Python 3.7 and printing out the version number:
python3.7 -V
# expected output
Python 3.7.3
Now we have successfully completed the installation of Python. Since we want to work with other Python packages in the future, we can now install the package management program PIP. For this we execute the following command:
sudo apt-get install -y python3-pip
In the following, we make sure that Python 3.7 is the latest python3 version. To achieve that we set a symbolic link to python3.
sudo ln -sf /usr/bin/python3.7 /usr/bin/python3
Once PIP has been installed we have to update PIP. Unfortunately we have to do this manually although we have just installed PIP, cause the installed version is pretty old, so yes, this step is necessary:
python3 -m pip install --upgrade pip
Once the installation is complete we also confirm this by calling the version number of PIP:
python3 -m pip -V
# expected output
pip 19.2.1 from /home/vagrant/.local/lib/python3.7/site-packages/pip (python 3.7)
Now we are still testing if we can actually install libraries with PIP. For this we use a very popular Python math library named numpy
python3 -m pip install numpy
