Install direct from github source - RuntimeTools/appmetrics GitHub Wiki

You will need a git client and a compiler to install from source. See Prerequisites for building appmetrics from source code.

Trying to run npm install with a github url does not work because appmetrics uses submodules. Instead use:

git clone --recursive https://github.com/RuntimeTools/appmetrics.git
npm install appmetrics

or for the latest release (e.g. 2.0.1):

git clone --recursive https://github.com/RuntimeTools/appmetrics.git appmetrics_latest
cd appmetrics_latest
git checkout tags/2.0.1
cd ..
npm install appmetrics_latest
