AssertionError raised #61

Closed tanducmai closed 2 years ago

tanducmai commented 2 years ago

My OS: WSL2 Ubuntu.

After I installed this package on Ubuntu using python3 -m pip install code2flow, I try with a python file:

code2flow a.py

The AssertionError is raised:

  File "/home/henry/.local/lib/python3.8/site-packages/code2flow/engine.py", line 725, in code2flow
    raise AssertionError(
AssertionError: Can't generate a flowchart image because neither `dot` nor `dot.exe` was found. Either install graphviz (see the README) or, if you just want an intermediate text file, set your --output file to use a supported text extension: {'json', 'gv', 'dot'}

I tried installing the graphviz package using python3 -m pip installgraphviz`, I received another error:

So my guess is that you missed installing the Graphviz package (not the pip install but the actual executable). You can install that here https://graphviz.org/download/

Feel free to reopen if this wasn't it
