I was looking for a package management tool and a runtime version management tool in Python which has the same role as
nodebrew in the node.js environment.
But in Python, there are so many, or more like too many, same kinds of tools, and top of that, they sound very similar. Which one should I use for my project?
I’m new to Python, therefore there are several misunderstands for sure. Any comments and corrections are welcome.
Pyenvto manage the multiple version of Python.

Virtualenv separates environments
pip installs all packages in global, there is a big problem. If you are working for more than two projects on the same computer, and if the projects depending on the same package but a different version. it’s going to conflict. To solve that problem, Virtualenv was made.
Virtualenv, we can install the packages for each project locally like
Pipenv the BEST way to manage packages

Failed to install Python 3.6.6 on Mac High Sierra
There was a problem when I tried to install Python 3.6.6 on my Mac.
zipimport.ZipImportError: can't decompress data; zlib not available
If you have the same problem, you can solve that by passing those compile options shown below.
env CFLAGS="-I"(brew --prefix openssl)"/include -I"(xcrun --show-sdk-path)"/usr/include" \ env LDFLAGS="-L"(brew --prefix openssl)"/lib" \ pyenv install -v 3.6.6
Next step, direnv
I found something seems very useful called direnv - unclutter your .profile. We can control environment variables depending on the current working directory. I’ll check this later, I might.
Thank you for reading, see ya again ;)
