Bug description:

I am trying to install the mdtex2html library, and while it works seamlessly on my local machine, on Replit I get an error.

--> poetry add 'mdtex2html 1.2.0'

  TypeError

  expected string or bytes-like object

  at venv/lib/python3.10/site-packages/poetry/core/utils/helpers.py:27 in canonicalize_name

Expected vs Current Behavior:

The package should install instead of giving this error.

Steps to reproduce:

Try to install the mdtex2html using the package manager or even from the console.

We also tried this in a normal Repl and had the same problem.

Try typing poetry add mdtex2html into the shell instead of poetry add 'mdtex2html 1.2.0'.

I was able to successfully import the mdtex2html module in my repl.

Try to fork your repl and in this repl enter the command poetry add mdtex2html into the shell.

What I’ve done is started a brand new Python repl. I haven’t done anything except run the following. The error I get this time is a bit different. Here is the link: Bare Python - Replit

~/Bare-Python$ poetry add mdtex2html
Using version ^1.2.0 for mdtex2html

So… Is the package already installed and pip/poetry isn’t aware of it?

7

I don’t know. Also, we shouldn’t discount the possibility that the two errors I get in a new Python repl and the one in the first post are for different reasons.

8

I forked your empty Python repl and was able to install the module successfully.

9

Hmmm, in that case, maybe the installation is failing because I am using the Free tier of Replit. I’ll try upgrading and see how it goes. It might be failing due to the machine running out of memory during the install.

10

Actually even without upgrading it worked for me just now in both in the Bare Python replit and a fresh one. But in the first one I still get the same error. That is where we actually need this library to install.

11

I also use the free plan in Replit. See the amount of free memory here: https://replit.com/account#resource-usage

12

Mhh, maybe just starting a blank Repl and importing the project from Github would work. I mean, would enable us to install the library.
