在macOS Sierra上使用git-review进行RequestsDependencyWarning

Question

I've just upgraded (using homebrew ), my git-review today from 1.26 to 1.27. I've got Python 3 installed on my system as well (macOS Sierra).

When I try to submit patch for review using git review -R , I get this error;

/usr/local/Cellar/git-review/1.27.0/libexec/vendor/lib/python3.7/site-packages/requests/__init__.py:91: RequestsDependencyWarning: urllib3 (1.24) or chardet (3.0.4) doesn't match a supported version! RequestsDependencyWarning)

I've searched online and came up empty, maybe this is a compatibility issue with the latest version of git-review on macOS Sierra with Python packages?

Answer 1

我用brew reinstall git-review修复了它，可以尝试一下。

Answer 2

The requests library defines a highest supported version of urllib3 – when a new version of urllib3 comes out, it is tested and once it is confirmed to work, a new version of requests that supports it is released. This doesn't necessarily mean that the previous version won't work, just that it is untested.

Apparently git-review vendors its dependencies, ie it uses a pinned version of the requests and urllib3 libraries. For this release, they seem to be using an untested combination of the two. Git-review continues to work just fine for me, so I think the warning is safe to ignore and should disappear in the next release, when they (hopefully) vendor compatible versions.

All that said, Index's suggestion of reinstalling git-review fixed it for me. (That somehow updated the vendored requests from 2.19.1 to 2.20.0) Not sure what's going on there.
