That's the error message I got in Google Colab, I don't know where else I can get a log.

For reproduction, enter pip install thriftpy2 on Google colab notebook cell.

Sorry, I can't reproduce the issue.

[PDXDJN]

I get the same error.

so, I tried installing all recent thriftpy2 versions directly, and none of them work: It was working without issue until about a week ago.

[aisk]

What's the pip / setuptools / python version?

[PDXDJN]

python 3.10.12 pip 23.1.2 setuptools 67.7.2

[aisk]

Tried the pip / setuptools with provides versions combination, still can't reproduce the issue. I don't have a access for the colab, if some one knows the different between it and a linux environment, please point out.

Some one provided me a Google colab access, and after running pip install thriftpy2 -v, the error log is:

So I think this is related to https://github.com/Thriftpy/thriftpy2/issues/218, which is already fixed in master branch. I think we should make a release cc @ethe

This should be resolved since v0.14.7 was published.
