Development Server Installation Instructions Incomplete

[milelime]

Is your feature request related to a problem? Please describe.

When installing the Oppia development server for Linux, the instructions do not fully list the packages that the user needs to install via pip install.

Describe the solution (or solutions) you'd like

The following packages need to be added to the installation instructions:

• psutil
• certifi
• packaging
• rcssmin
• xmltodict

Additional context

I will happily fix this via PR. If approved to work on it, I will make the necessary changes to the relevant wiki pages, adding these packages to the relevant pip install lines.

Proposed fix

I am interested in fixing this issue. I plan to make changes to this wiki page in this section:

Install the Python dependencies:

$ pip install pyyaml setuptools
Requirement already satisfied: setuptools in /home/user/.pyenv/versions/2.7.18/envs/oppia-tmp/lib/python2.7/site-packages (44.1.1)
Collecting pyyaml
  Downloading PyYAML-5.4.1-cp27-cp27mu-manylinux1_x86_64.whl (574 kB)
     |████████████████████████████████| 574 kB 2.3 MB/s
Installing collected packages: pyyaml
Successfully installed pyyaml-5.4.1

Note that you don't need to install pyyaml if you were able to install python-yaml with your package manager earlier.

I plan to change pip install pyyaml setuptools to pip install pyyaml setuptools psutil certifi packaging rcssmin xmltodict.

@HardikGoyal2003 Could you please take a look when you get a chance, thank you.

Hi @milelime I don't think the user needs to install any packages manually during the installation. If this is related to any issue you are running into, please feel free to open a new discussion here: https://github.com/oppia/oppia/discussions

@HardikGoyal2003 users definitely need to manually install packages during the installation. Without doing so, running the dev server script fails and informs you that some dependencies are missing.
