Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
Could not symlink Frameworks/Python.framework/Headers
Target /usr/local/Frameworks/Python.framework/Headers
is a symlink belonging to python@2. You can unlink it:
  brew unlink python@2

To force the link and overwrite all conflicting files:
  brew link --overwrite python

To list all files that would be deleted:
  brew link --overwrite --dry-run python

Possible conflicting files are:
/usr/local/Frameworks/Python.framework/Headers -> /usr/local/Cellar/python@2/2.7.16/Frameworks/Python.framework/Headers
/usr/local/Frameworks/Python.framework/Python -> /usr/local/Cellar/python@2/2.7.16/Frameworks/Python.framework/Python
/usr/local/Frameworks/Python.framework/Resources -> /usr/local/Cellar/python@2/2.7.16/Frameworks/Python.framework/Resources

==> Caveats
Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

If you need Homebrew's Python 2.7 run
  brew install python@2

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

See: https://docs.brew.sh/Homebrew-and-Python
==> Summary
🍺  /usr/local/Cellar/python/3.7.6_1: 3,977 files, 61MB

다음과 같이 brew link 관련해서 오류가 뜬다면

$ brew unlink python@2

를 해주면 정상적으로 연동되는 것을 확인할 수 있다.

cql 설치하기

이때 pip가 설치되어있어야한다.

$ pip install --upgrade pip
$ pip install cql

cassandra 사용하기

cassandra 시작하기

$ brew services start cassandra

cassandra 종료

$ brew services stop cassandra
