brew upgrade
I updated it without any problem, but there was also Warning.
#### **`Warning: Building python from source:`**
The bottle needs the Apple Command Line Tools to be installed. You can install them, if desired, with: xcode-select --install```
$ xcode-select --install
And still the following error ...
xcode-select: note: install requested for command line developer tools
-Install command line developer tools
All solved with the above.
