MarkBind version

5.5.2

Describe the bug and the steps to reproduce it

$ markbind deploy -n
  __  __                  _      ____    _               _
 |  \/  |   __ _   _ __  | | __ | __ )  (_)  _ __     __| |
 | |\/| |  / _` | | '__| | |/ / |  _ \  | | | '_ \   / _` |
 | |  | | | (_| | | |    |   <  | |_) | | | | | | | | (_| |
 |_|  |_|  \__,_| |_|    |_|\_\ |____/  |_| |_| |_|  \__,_|

 v5.5.2
error: The "path" argument must be of type string. Received undefined

To reproduce run markbind deploy locally. It worked for me on WSL2 but it seems like it may not be working for Windows. Note: once we set the cache_dir env variable it will work.

Expected behavior

Should work without the need to explicitly setting cache_dir

Anything else?

We updated gh-pages and it started to not work. Related to this update which introduced the cache folder. Related to the v3.1.0 update for github pages.

For ease of reference, I'm posting here the current remedy for Windows:

Run the following command in the terminal used for running the markbind deploy command:

set CACHE_DIR=cache
