Can't get it installed

[Quikko]

Hi there,

After given the command to launch the back-end server (npm run server
), I receive following error:

Any idea how to solve this?

I had the same issue and solved by installing Visual Studio Enterprise 2015 (The issue of because of no C++ compiler).

If you are on windows you can try:

npm install --global --production windows-build-tools

or better:

npm --add-python-to-path i -g windows-build-tools

as suggeted here #5 (comment)

With admin privileges. I had it installed but seems that it stopped working when i installed another VisualStudio

Also you can get update argon2 i think. It fixes the installation process on Windows10 + Python 2.7 + NodeJs12
