Fix prebuild failing when NODE_ENV is set to production

[arthuro555]

A build server was throwing this error:

npm WARN config production Use `--omit=dev` instead.
npm WARN config cache-min This option has been deprecated in favor of `--prefer-offline`.
npm WARN using --force Recommended protections disabled.

Looking at package.json, I assume that the npm install is to install the build tools. Since afaik the server is using NODE_ENV to tell npm to run in production mode, and the command did not override the mode, it would install the dependencies in production mode, not installing the build tools.

I have not tested the fix but I assume this will do.

For me also it looks OK but could you please test and report it here?

Yep, I tested on the build server that showed issues, using my branch makes the build succeed 👍
