Upgrading to Nodejs 8 and "error: failed to commit transaction" - node.js

Question

I am trying to upgrade my nodejs 6 to 8 in my arch linux. So I did:
$ sudo pacman -S nodejs npm
Result:
resolving dependencies...
looking for conflicting packages...
Packages (3) openssl-1.0-1.0.2.l-1 nodejs-8.1.3-1 npm-4.6.1-1
Total Installed Size: 39.22 MiB

Errors occurred, no packages were upgraded.
And now my nodejs is broken I think!
$ node --version
node: error while loading shared libraries: libhttp_parser.so.2.7.1: cannot open shared object file: No such file or directory
Any ideas what should I do now?

I had same problem and this is how I solve it :
sudo pacman -S nodejs npm --force
Option --force will upgrade your package even if you get warning with existing files.
After this you need to install http-parser with pacman so :
sudo pacman -S http-parser --force
Finally, node -v will give you this error :
error while loading shared libraries: libicui18n.so.59: cannot open shared object file: No such file or directory
To fix it, install icu lib from pacman :
sudo pacman -S icu --force
Here we go, your node version is now v8.4.0.
Edited 17/01: --force was deprecated. Please use --overwrite
