How can I Install pip for python 3.7 on Ubuntu 18?

I've installed Python 3.7 on my Ubuntu 18.04 machine. Following this instructions in case it's relevant: > Download : Python 3.7 from Python Website [1] ,on Desktop and manually > unzip it, on Desktop Installation : Open Terminal (ctrl +shift+T) > > Go to the Extracted folder > $ cd ~/Desktop/Python-3.7.0 > $ ./configure > $ make > $ sudo make install > > Making Python 3.7 default Python : > > $ sudo vim ~/.bashrc > press i > on the last and new line - Type > alias python= python3.7 > press Esc > type - to save and exit vim > :wq > now type > $ source ~/.bashrc From here: https://www.quora.com/How-can-I-upgrade-Python-3-6-to-3-7-in-Ubuntu-18-04 I've downloaded several modules through `pip install module` but when I try to import them, I get a `ModuleNotFoundError: No module names 'xx'` So I did some research and apparently when used pip to install, it installed in the modules in previous version of Python. Somewhere (probably a question in SO) I found a suggestion to install the module using `python3.7 -m pip install module` but then I get `/usr/local/bin/python3.7: no module named pip`. Now I'm stuck, pip is installed, but apparently not for Python 3.7. I'm assuming that if I can install pip for Python 3.7, I can run the pip install command and get the modules I need. If that is the case, how can I install pip for python 3.7, since it's already installed? --- This is the best I have come up with: I have installed python 3.7 successfully and I can install modules using pip (or pip3) but those modules are installed in Python 3.6 (Comes with ubuntu). Therefore I can't import those modules in python 3.7 (get a module not found) Python 3.7 doesn't recognize pip/pip3, so I can't install through pip/pip3. I need python 3.7.
