Things seem to start breaking around 10:54am Jun 11 according to this dashboard:

https://fusion.corp.google.com/projectanalysis/summary/KOKORO/prod:grpc%2Fcore%2Fpull_request%2Flinux%2Fgrpc_basictests_python

All the Python tests are failing with this error

SyntaxError: Non-ASCII character '\xc3' in file /var/local/git/grpc/py27_gevent/local/lib/python2.7/site-packages/rsa/key.py on line 1, but no
encoding declared; see http://python.org/dev/peps/pep-0263/ for details

Maybe something to do with a new release here: https://pypi.org/project/rsa/#history and sybrenstuvel/python-rsa#152. A similar fix: googleapis/google-auth-library-python#528.

I am having the same issue happening from today,

SyntaxError: Non-ASCII character '\xc3' in file /otlplus/venv/lib/python2.7/site-packages/rsa/key.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

I have the same error. I think the name Sybren A. Stüvel is the issue. But looking at git blame, it was modified 9 years ago. Not sure why we are seeing this error now. It was okay for me with rsa 4.0 but not rsa 4.2.

@ttwd80 me too. I could solve with rsa 4.0. In rsa 4.2, python 3 style is used, ex., 54 line : def __init__(self, n: int, e: int) -> None: (https://github.com/sybrenstuvel/python-rsa/blob/master/rsa/key.py#L54).

Could this be the change that broke everything? https://github.com/sybrenstuvel/python-rsa/commits/master/rsa/key.py

[sybrenstuvel]

I fixed it in the Python-RSA package so that package managers now know which version they can use. Python-RSA 4.3 is now the last one to support Python 2.7, version 4.4 explicitly requires Python 3.5+.

Hope this is now resolved for you, if there are still issues let me know.

[John-Oula]

Has anybody solved this yet?
def init(self, n: int, e: int) -> None: Syntax error

Im on python3.7

[n3yron]

I have Python 2.7. Fixed via:
pip uninstall rsa
pip install -v rsa==4.0
As the last version with Python 2.7 support was Python-RSA 4.0.

pip uninstall -y rsa to avoid the prompt if you're automating this in a Dockerfile etc.
