TomlError when building with pybase64

[MustafaErkinDal]

Hi,

I have been using this SDK for over a year in my Android project and suddenly it started to not build itself. I could not find any solution. I will be appreciated if you can help me. My python version on my macbook is 3.8.10

Thank you in advance.

My error:

Your pip section is currently set to use the newest possible version of each requirement, so your app may change whenever they make a new release. It would be a good idea to use the == syntax to pin them to a specific version. In particular, you can probably solve your current issue by using an older version of pybase64.

Alternatively, you could upgrade to a newer version of Chaquopy. From the "looking in indexes" line, your current version is apparently 13.0.0 or older. I believe this particular issue was fixed in version 14.0.2, but if possible I recommend you use the most recent version.
