I tried re-install python3, it doesn't work.
Any solution here?

I am trying to fix pip but I'm in a state where it's installed but also not installed?
When I type "pip" in terminal, I get that pip is not installed.
When I type "pip3" in the terminal, I get the following:
Traceback (most recent call last):
File "/Applications/Xcode.app/Contents/Developer/usr/bin/pip3", line 5, in <module>
from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip'
How do I get rid of pip?
I also tried to run "python3 get-pip.py" again (download again), but I got the following error:

As the command failed on Downloading libxslt into libs/libxslt-1.1.33.tar.gz from ftp://xmlsoft.org/libxml2/libxslt-1.1.33.tar.gz
I browsed the ftp://xmlsoft.org/libxml2/ site which doesn't have ftp://xmlsoft.org/libxml2/libxslt-1.1.33.tar.gz, only ftp://xmlsoft.org/libxml2/libxslt-1.1.33-rc1.tar.gz.
Is this the problem, and if so is there a way to override it in the package? Or am I missing something?
You can bypass FTP errors while still having the STATIC_DEPS functionality by downloading libxml2 and libxslt manually and building from setup.py.
Pasted from the lxml website:
...If you want to use
specific versions, or want to prevent any online access, you can
download both tar.gz release files yourself, place them into a
subdirectory libs in the lxml distribution, and call setup.py with the
desired target versions like this:
python setup.py build --static-deps \
--libxml2-version=2.9.1 \
--libxslt-version=1.1.28 \
sudo python setup.py install
