Trouble trying to install ssh2-python on Mac (OS Catalina)

Question

I am trying to download ssh2-python, but continue to get this error. I saw a previous post said to download cmake to fix this issue, but unfortunately it did not help me. Any recommendations on what to do seeing the error below? Thank you!

pip3 install ssh2-python

You need cmake to compile the lib. If you have homebrew installed, use the following command to install the cmake . Then open a new terminal and try to install the ssh2-python.

brew install cmake
