Build fails with Python 3 due to old node-gyp version requirement

Describe the Bug

"npm install" command fails when Python 3 is used by NPM because node-gyp package version requirement in package-lock.json is 3.8.0 which does not support Python 3 per the recent comments on nodejs/node-gyp#1337

Steps To Reproduce

1. Install a version of Python 3 on the system
2. git clone https://github.com/bitwarden/web.git web-vault
3. cd web-vault
4. npm install
5. Observe the error message

Expected Result

npm install completes successfully.

Actual Result

npm install fails.

Environment

• Operating system: FreeBSD 12.1-RELEASE
• Browser: N/A
• Build Version (Bottom of the page): [2.16.1]

Additional Context

Installing Python 2.7 on the system, executing npm config set python python2.7, and then running npm install again works to make the build finish successfully.

Hi @Barracuda6 thank you for your detailed report. With us recently replacing node-sass (which was deprecated) in favor of sass, this issue shouldn't come up anymore. sassdoes not rely onnode-gyp`, hence no need to compile it with python.
