问题
I installed python3 with homebrew but it does not create symlink to pip3.
When I installed it former, homebrew created pip3 symlink at /usr/local/bin.
But now it does not create.
Note that I know there is a solution I am able to create symlink manually,
But I don't know why homebrew does not create symlink to pip3 despite python formular looks like create symlink. (see formula of python3 on github)
I using:
macOS 10.13.4
python 3.6.5
Homebrew 1.6.6
Homebrew/homebrew-core (git revision d4c0; last commit 2018-05-26)
