### node-gyp problems
node-gyp can cause problems, because it requires a C++ compiler.
If you do have problems caused by it, first follow the installation steps for your OS [here](https://github.com/nodejs/node-gyp#installation).
If you still have problems and are on Windows, try the following:
- run `npm config set msvs_version 2015` before `npm install`
- Repair Windows Build tools that the node-gyp doc made you install. If it tells you to remove a conflicting version do it. After the repair succeeded, reboot.
