The logger writes everything twice into the logfile. about wexpect

[nmz787]

trying to set that ENV var in the script:

import os
os.environ['WEXPECT_SPAWN_CLASS'] = 'SpawnPipe'
os.environ['WEXPECT_LOGGER_LEVEL']='INFO'
from wexpect import spawn
from wexpect import TIMEOUT, EOF

yields this error at the end of my script

this looks relevant to my exception:

[that user's] code used to work until Python 3.4. I know because I've just run into the same issue, calling open() within del. Apparently built-in functions no longer work, because of a change in when del is run as the interpreter shuts down.

@nmz787 , your issue is another logging issue. I suggest to open a new issue for that.
The duplicated logging issue has been solved.

v3.3.1 fixes this issue.

Upgrade your installation with:

python -m pip install --upgrade wexpect
