Latest version of node and npm causing problems in running karma. When I try to install karma-cli npm i -g karma karma-cli I get following warning:

I am not able to get karma version installed, I think it's not installed properly in my machine.

Finally, optionalDependencies are dependencies that don't necessarily need to be installed. If a dependency can be used, but you would like npm to proceed if it cannot be found or fails to install, then you may put it in the optionalDependencies object.
The --no-bin-links argument will prevent npm from creating symlinks for any binaries the package might contain. The --no-optional argument will prevent optional dependencies from being installed. The --no-shrinkwrap argument, which will ignore an available shrinkwrap file and use the package. json instead.
How to prevent npm install with an unsupported Node. js version. It turns out you can add a local npm configuration file ( . npmrc ) to your module/project root and explicitly turn on strict Node.
Method 1: Using npm update command to update the node package manager. Method 2: Using npm@latest command to update the node package manager. Method 3: Using PPA repository (only for Linux). Method 4: Using cache cleaning & stable installing (only for Linux).
This is not an error. It is a warning that fseventsd, which is Mac OS specific, cannot be installed on Linux.
There is no need to be alarmed, and the package that needs fsevents will still work - that's why it's an optional dependency.
Since many people are confused about this (particularly since this used to be a real error, not a warning) there's an open bug to make the current warning into an INFO instead
Additionally yarn already does this.
