error: can't copy 'build/lib.macosx-10.15-x86_64-3.8/_re2.cpython-38-darwin.so': doesn't exist or not a regular file

When the ’ (RIGHT SINGLE QUOTATION MARK ; HTML ’ HEX 0x2019 ) is in the string to search the span is displace by 2, for example:

string = "it’s your car"
regex = re2.compile('you')
match = regex.search(string)
pather_match = string[match.start():match.end()]
print(pather_match)

'ur c'

As you known, regexp and match object always create some dynamic members with attr_dict, which can't be display in the dir() function result, we should add a static member dict point to the dict

Please refer to the commit, thanks

While I suspect there is some specific local environment issue that produces this awful result, I think that we need to prevent it from building/installing a broken package.

pip install fb-re2
python -c "import re2; re2.compile('foo')"
[1]    99748 segmentation fault  python -c "import re2; re2.compile('foo')"

I was able to reproduce the error with both python3.6 and pyton3.7 installed using pyenv.

After June 2022, ABSL no longer supports c++11, so it cannot build anymore.

See PR #17 that should fix this issue. No license included is an issue for distribution packaging.
