nw install fails on Debian 10

[sid-the-sloth]

Trying to install nw as per readme.md under: https://github.com/zcbenz/nw-sample-apps

nw installation fails - can't figure out the failure reason even after reading the error log.

Please help.

On Debian 10, running with sudo for system-wide installation:

$ sudo npm install -g nw

The last part of the error log:

Many thanks!

Solved:

The correct way to install system-wide on GNU/Linux, from root account:

# npm install --unsafe-perm=true -g nw

or, from user account:

$ sudo npm install --unsafe-perm=true -g nw

Perhaps the readme.md at https://github.com/zcbenz/nw-sample-apps can be updated to reflect that. Thank you!
