Installing TinyGo results in Command Line Tools (CLT) SDK folder names mismatch on macOS

Question

When following the TinyGo Quick Install Guide for macOS I'm running into the following error: Error: The contents of the SDKs in your Command Line Tools (CLT) installation do not match the SDK folder names.

% brew install tinygo
==> Installing tinygo from tinygo-org/tools
Error: The contents of the SDKs in your Command Line Tools (CLT) installation do not match the SDK folder names.
A clean reinstall of Command Line Tools (CLT) should fix this.

The full install instructions are just two commands:

% brew tap tinygo-org/tools
% brew install tinygo

The CLT are currently installed in /Library/Developer/CommandLineTools as shown by xcode-select --print-path:

% xcode-select --print-path
/Library/Developer/CommandLineTools

pkgutil shows I have the latest install:

% pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 13.4.0.0.1.1651278267
volume: /
location: /
install-time: 1654474872
groups: com.apple.FindSystemFiles.pkg-group 

Reinstalling Command Line Tools results in the path being the same and confirmed in this article "How to Install Command Line Tools in Mac OS X (Without Xcode)". Where does TinyGo want the Command Line Tools to be installed and how can it be installed there?

Answer 1

TinyGo's installer for macOS requires Command Line Tools to be installed in the alternate location used when Xcode is fully installed (not just the Command Line Tools): /Applications/Xcode.app/Contents/Developer.

After installing Xcode (much larger package than just the CLT), xcode-select will show the alternate location which enables TinyGo to be installed:

% xcode-select --print-path
/Applications/Xcode.app/Contents/Developer
