I'm having the same issue.

This error is saying that it can't install the sharp dependency which is an image processing library. Please check or post to their repo for troubleshooting.

From a quick search through their issues, it looks like you may need to manually install libvips (source). Changing your Node.js version may also work as it'll download a precompiled version of sharp instead of trying to compile it fresh.

Please follow-up with the sharp repo.

Thanks!

@transitive-bullshit You were correct about changing the Node.js version fixing that issue, thank you!

@Cozy19 If you're still having a problem installing ffmpeg-concat on Ubuntu 18.04 as root, it's probably because the version of Node.js in the default repos is out of date. You can update it and it should work, try this:

`

Clean out the old Node stuff

apt remove --purge nodejs npm
apt clean
apt autoclean
apt install -f
apt autoremove
rm -rf /usr/lib/node_modules/*

Install the Node PPA

curl -sL https://deb.nodesource.com/setup_10.x -o nodesource_setup.sh
chmod +x nodesource_setup.sh
./nodesource_setup.sh

Install Node & NPM (one command)

apt install -y nodejs

Install ffmpeg-concat

npm install --unsafe-perm -g ffmpeg-concat
`
I had to add the "--unsafe-perm" to be able to install, otherwise it would fail on the node-gyp dependancy.
