Can't install on a clean macOS without git installed

[PeterDaveHello]

Install nvm on a clean macOS will fail as below:

$ curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.8/install.sh | bash

=> xcode-select: note: no developer tools were found at '/Applications/Xcode.app', requesting install. Choose an option in the dialog to download the command line developer tools.
Failed to clone nvm repo. Please report this!

It'll also open a dialog to ask about installing Xcode with command line tools or not:

The problem is because the path /usr/bin/git is actually the built-in Xcode, so nvm can find git successfully and assume git is installed and working.

I'm not sure how this can be addressed; typically the first thing you always have to do (manually) when setting up a new Mac is install the Xcode command line tools.

I haven't found a method to suppress the GUI dialog asking to install Xcode command line tools, otherwise we can at least escape from that failure without providing useful info :(

I think that installing those prior to doing anything else - including installing nvm - is just something Mac devs need to know how to do.

[PeterDaveHello]

Maybe I can send a PR to just mention that README.md?

[ljharb]

I suppose, but i still think it’s something that a Mac dev just needs to know, and I’m not sure why they’d be learning it at the point of installing nvm.

[PeterDaveHello]

I'll like to mention that also because we can't properly handle it, we don't know if anyone would install nvm first ;)

[ljharb]

i suppose, sure
