Linux Error installing sharp

I have been working on development on the mac and it seems to be working fine so I thought on deployment things could be just fine since the docs are pretty much similar for installation.

Unfortunately, I am getting the following error log:

is the building mainly failing because of the Linux version no being drawing or something else is happening here?

I am currently using Ubuntu 16.04 and I tried installing using sudo npm install --save sharp I also tried using npm install --build-from-source

Strange thing is that the user I tried the install has is not the root user but it has sudo privileges and would install about anything without any problem also I tried using the service terminal and it had the same issue.

At the end your solution worked using npm install --unsafe-perm I am not sure about this flag capability I could not find it as a reference on npm but thanks for all

I recommend avoiding the use of sudo/root when installing via npm, but if you do, npm’s --unsafe-perm flag is required, as is the case for all native modules and not just sharp.
