This is done so that the output from npm doesn't interlace with the output of your script. We always want to disable progress bars during exec.

The idea is to make the libnpmexec don’t output npm logs.
npm log output is interlacing with the output of the application executing libnpmexec.
Just passing the stdio value through is not enough.

This isn't npm log output, this is progress bars specifically.

To suppress all logging we need npmlog.pause and npmlog.resume, but these should be independent of enabling/disabling progress.

I don't want to install npmlog directly to pause it.
What about a flag to ignore npmlog?

I mean, I have ora as progress bar.
npmlog and ora are mangling the output.
I need to install and import npmlog in my project to pause the npmlog.
And that does not guarantee that the npmlog is muted due to hoisting.

npmlog.enableProgress()
