AWSCLI SyntaxError: Non-ASCII character '\xc3' error

I am working on a Ruby on Rails project where AWSCLI is used. Recently, When I push my code to Staging, it tries to import newkeys, PrivateKey, PublicKey from rsa.key and throws an error.

Error message is as follows:

SyntaxError: Non-ASCII character ‘\xc3’ in file /opt/circleci/.pyenv/versions/2.7.12/lib/python2.7/site-packages/rsa/key.py on line 1, but no encoding declared; see PEP 263 -- Defining Python Source Code Encodings | Python.org for details

My circleci/config.yml file is as follows:

I don’t understand how to resolve this problem.

Hi @micheldas1,

The config file you posted is fairly large and also looks to be edited and malformed so it’s a little hard to come to conclusions about what exactly is going on, especially without access to your code.

I would recommend trying to reproduce the problem slowly by building up an example config file that’s safer to post in full somewhere as well as full logs. Using the CCI CLI would be a convenient way to do that.

My initial thought, though, just as a wild guess, is that your caches are bad in some way and need to be blown. Adding something like *-v1-* to your cache keys would do that and also give you a way to blow these caches going forward by simply incrementing that number. But again, that’s kind of a wild guess.

Good luck!
