gsutil flag '-m' exception with Python 3.8 #1085

Open ghost opened 4 years ago

ghost commented 4 years ago

gsutil works with Python 8 until you use the '-m' flag:

python -V -> Python 3.8.3

Your current Cloud SDK version is: 304.0.0

gsutil -m cp -r gs://foo-bar/* .

Probably better if you post the same command with -d added to get debug info.

gsutil -d -m cp -r gs://foo-bar/ . gsutil -d cp -r gs://foo-bar/ .

Without '-m' works fine, see attached log for with '-m'
