Answer 1

I ran into the same problem while installing scrapy. The solution for me was a little bit different, not the file pip_vendor\\pkg_resources__init__.py, but the \\pip\\compat__init__.py, I've changed line 75 to mbcs, and then pip installed scrapy successfully!

After that, I changed that line back to utf-8.
