node-gyp-build error bootstrapping truffle

[kevinweaver]

While running yarn bootstrap in the root Truffle monorepo, I encountered an issue with node-gyp:

error /Users/.../truffle/node_modules/leveldown: Command failed.
Exit code: 1
Command: node-gyp-build

I was able to resolve this issue following these troubleshooting steps:

1. Ensure you have installed node-gyp globally:

$ npm install -g node-gyp

2. Ensure you have a version of Python 2.x accessible. If you use pyenv, you can see what version you have installed with:

$ pyenv global
3.10.4

If a 2.x version is not listed like the example above, find and install the latest version. Example:

$ pyenv install 2.7.18

You should now find it in the versions list:

$ pyenv versions
system
2.7.18
* 3.10.4 (set by /Users/yourname/.pyenv/version)

Now add the new version to your version file: ~/.pyenv/version

2.7.18
3.10.4

You should now see that it is globally accessible:

$ pyenv versions
system
* 2.7.18 (set by /Users/yourname/.pyenv/version)
* 3.10.4 (set by /Users/yourname/.pyenv/version)

This resolved my issue building truffle.
