litstudy Package Installation Python

Question

I am Trying to do Co-Citation Network analysis and have to install package called "litstudy" in Python but I am getting an Error installing it in Jupyter and Python 3.10

Link for litstudy package https://nlesc.github.io/litstudy/index.html

In Python 3.10 while installing from Command Prompt getting Error

C:\\Program Files (x86)\\Microsoft Visual Studio\\2022\\BuildTools\\VC\\Tools\\MSVC\\14.32.31326\\bin\\HostX86\\x64\\cl.exe' failed with exit code 2 [end of output] note: This error originates from a subprocess, and is likely not a problem with pip. error: legacy-install-failure

It Gets installed in Jupyter but when I import the package I get error

 import litstudy

If anyone can Solve this for me i will be really grateful I'm stuck on this for amost a day and need to get started with networking analysis or if you have any other solution like this for Citation Networking

TL;DR

• Dependencies of the litstudy package are not compatible with Python 3.10, you will have to downgrade to 3.9
• Install packages from conda-forge, using conda, so you don't have to compile them.

The long story

The litstudy package has a huge number of dependencies, several of which need to be compiled. The error message you got indicates that compilation failed for some one them.

The dependencies wordcloud and fa2 where a problem on my computer when I ran pip install litstudy to reproduce your problem.

For wordcloud, the exists a pre-compiled Conda bundle for it, available from conda-forge. I recommend using conda (Anaconda3 or Miniconda3, either will do).

This worked for wordcloud, as recommended by its own readme:

conda install -c conda-forge wordcloud

For fa2, there was a second problem: when I ran conda install -c conda-forge fa2, I got this message:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

  - fa2 -> python[version='>=3.6,<3.7.0a0|>=3.7,<3.8.0a0|>=3.8,<3.9.0a0|>=3.9,<3.10.0a0']

Your python: python==3.10.4

which basically says fa2 is not compatible (yet) with Python 3.10. So, you will have to downgrade to a 3.9.x version of Python to use this package.

So to install litstudy and its dependencies, I just created a Python 3.9.12 environment using conda, and then I was able to install everything.

The cut-and-pastable solution

Putting it all together, this worked for me, after installing Miniconda3:

conda create -n py39 python==3.9.12
conda activate py39
conda install -c conda-forge fa2 wordcloud
pip install litstudy

In that environment, import litstudy works fine.
