Can you share the output of brew doctor, brew config, and brew info newt?

What files are in /usr/local/Cellar/newt/0.52.18/lib/python2.7/site-packages? Can you share brew gist-logs newt?

[tonysh]

@tdsmith :

No /usr/local/Cellar/newt/0.52.18/lib/python2.7/site-packages folder here.

$ ll /usr/local/Cellar/newt/0.52.18/lib/python2.7
ls: /usr/local/Cellar/newt/0.52.18/lib/python2.7: No such file or directory

[tdsmith]

ah. Looking at newt's configure script, it's not very clever. newt only looks in /usr/include for python headers. You should install the Xcode CLT to build the snack module with xcode-select --install and then run brew reinstall newt byobu.

[tonysh]

It WORKED, @tdsmith thanks a lot for your help!

[timothybasanov]

I had same problem. In addition to xcode --install and brew reinstall best byobu I missed brew python and brew install python was also required.

[gusutabopb]

I use anaconda as my Python distribution and had the same problem. To fix it, I followed the messages shown after reinstalling newt, namely:

mkdir -p /Users/<myusername>/.local/lib/python2.7/site-packages
echo 'import site; site.addsitedir("/usr/local/lib/python2.7/site-packages")' >> /Users/<myusername>/.local/lib/python2.7/site-packages/homebrew.pth

Works fine now!
