Cannot build Node on macOS: "No acceptable C compiler found!"

• Subsystem:

I have latest XCode (9.1 (9B55))& Command Line Tools installed on a fully updated High Sierra. python resolves to a version 2.7.10; I have make 3.81. This fulfills all requirements at https://github.com/nodejs/node/blob/master/BUILDING.md#unix--macos and yet when I run ./configure I get the following:

WARNING: failed to autodetect C++ compiler version (CXX=ccache clang++ -Qunused-arguments)
WARNING: failed to autodetect C compiler version (CC=ccache clang -Qunused-arguments)
Node.js configure error: No acceptable C compiler found!

        Please make sure you have a C compiler installed on your system and/or
        consider adjusting the CC environment variable if you installed
        it in a non-standard prefix.

If you have run xcode-select --install, the command line tools are installed and clang works from the command line, I'd suspect something might be wrong with ccache (since, as far as I can see, your $CC and $CXX env variables contain ccache clang -Qunused-arguments and ccache clang++ -Qunused-arguments). Maybe try to run something like ccache clang --version.

I don't seem to have the ccache command available. 🤔 Weird, I definitely have XCode & CLT installed. Homebrew doesn't complain and I've been able to install native Node deps that weren't pre-compiled (like node-sass) and it worked.

[aqrln]

ccache isn't a part of XCode and CLT, nor even a part of what one would call a "standard" C/C++ toolchain. If you haven't modified your CC and CXX environment variables yourself on purpose to use ccache, it's kinda weird how it got there. I'd suggest you to check your .bashrc/.bash_profile/.zshrc.

You're right, I had CC etc. redefined in ~/.zshrc; a byproduct of trying to compile Chromium in the past...

Sorry for taking your time and thanks for help! I'm closing the issue.
