Homebrew cannot find installed command line tools

Question

I have installed command line tools through Xcode. When I ran xcode-select -p, its showed /Applications/Xcode.app/Contents/Developer.

However, when I ran brew config, it showed CLT: N/A. And when I updated python using brew, it showed Warning: Building python from source: The bottle needs the Apple Command Line Tools to be installed.

Answer 1

I've got the same issue just now. Running xcode-select --install to reinstall Command Line Tools worked for me, brew config now reports CLT: 7.3.1.0.1.1461711523.

Answer 2

As xcode-select --install did not solve the issue for me:

I had to run brew doctor which listed Warning: Some installed formula are missing dependencies. including a brew install command to fix these. After running that, brew config reported CLT no longer as N/A.

Answer 3

Use sudo xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools, or use xcode-select --install to install the standalone command line developer tools.
