Python 3.7.1 - Githubissues

TessaI159 commented 5 years ago

Attempting to run

./waf configure --libdir /usr/lib/x86_64-linux-gnu/

with Python 3.7.1 results in an error.

Traceback (most recent call last):
  File "/home/tess/Clones/diodon-plugins/waflib/Node.py", line 490, in ant_iter
    raise StopIteration
StopIteration

The above exception was the direct cause of the following exception:

Switching to 3.6.7 using pyenv and installing diodon-dev and valac allowed me to build successfully. The following commands fixed the issue for me:

sudo apt install -y valac diodon-dev
pyenv local 3.6.7
./waf configure --libdir /usr/lib/x86_64-linux-gnu/

This issue appears to persist with Python 3.8.5

❯ python --version
Python 3.8.5

1nVitr0 commented 3 years ago

This is due to PEP 0497 that has been enabled since Python 3.7

gogowitsch commented 3 years ago

We could check the Python version during runime - or say to run Python 2 instead. See #15
