解決方法

npmのデフォルトディレクトリを作成する

$ mkdir ~/.npm-global
$ npm config set prefix '~/.npm-global'
$ echo ' export PATH=~/.npm-global/bin:$PATH' >> ~/.bash_profile
$ source ~/.bash_profile

npm -g install xxxに成功するようになった

$ npm -g install firebase-tools

/Users/xxx/.npm-global/bin/firebase -> /Users/xxx/.npm-global/lib/node_modules/firebase-tools/bin/firebase

> @google-cloud/functions-emulator@1.0.0-beta.4 postinstall /Users/xxx/.npm-global/lib/node_modules/firebase-tools/node_modules/@google-cloud/functions-emulator
> node scripts/upgrade-warning


If you're using the Emulator via the Firebase CLI, you can
disregard this message.

If you're upgrading @google-cloud/functions-emulator, these
are the recommended upgrade steps:

1.  Stop the currently running emulator, if any:

        functions stop

2.  Uninstall the current emulator, if any:

        npm uninstall -g @google-cloud/functions-emulator

3.  Install the new version of the emulator:

        npm install -g @google-cloud/functions-emulator

If you have trouble after upgrading, try deleting the config
directory found in:

    ~/.config/configstore/@google-cloud/functions-emulator

Then restart the emulator. You can also check for any renegade
Node.js emulator processes that may need to be killed:

    ps aux | grep node

+ firebase-tools@3.18.4
added 524 packages in 16.654s
