I am attempting to install VAPOR Python on my mac via the terminal. I created and activated a new conda environment but when I try to download VAPOR itself, I get stuck with this error:

‘xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun  
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun’

Any tips on how to solve this? Thank you!!!

Hi, you need to have the Xcode command line tools installed. You can do this with `xcode-select --install`
