node-gyp rebuild not working on MacOS Catalina Beta without reinstalling CommandLineTools #1861

Description

  • Node Version: v8.16.1 & v12.7.0

Yes, I know, it's obvious that there are some bugs on a beta OS, but I just wanted to share the solution because I couldn't find anything by googling.

To run node-gyp, you need to do this: xcode-select --install first, but if you already installed the command line tools in the past, this command will just output:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Using "Software Update" as suggested, won't fix this problem. You have to uninstall the command line tools first by deleting this folder:
/Library/Developer/CommandLineTools
reference

After doing that, you need to run xcode-select --install again and everything should work now.

However, even though node-gyp now finds your command line tools, it will still fail if you use a node version higher than v8.16.1, so consider downgrading to that momentarily (by using nvm for example...).

                      Yes, I know, it's obvious that there are some bugs on a beta OS, but I just wanted to share the solution because I couldn't find anything by googling.

                      To run node-gyp, you need to do this: xcode-select --install first, but if you already installed the command line tools in the past, this command will just output:

                      xcode-select: error: command line tools are already installed, use "Software Update" to install updates
                      

                      Using "Software Update" as suggested, won't fix this problem. You have to uninstall the command line tools first by deleting this folder:
                      /Library/Developer/CommandLineTools
                      reference

                      After doing that, you need to run xcode-select --install again and everything should work now.

                      However, even though node-gyp now finds your command line tools, it will still fail if you use a node version higher than v8.16.1, so consider downgrading to that momentarily (by using nvm for example...).
