Nvm: OSX Sierra node installation failed; Checksums does not match.

[serbiant]

Hello there,
I'm trying to install node.js using nvm 0.32.1. It fails. As you could see from the logs below, it says that checksums are different and the difference is just a slash at the beginning.
``
Tagays-MacBook-Pro:~ serbiant$ nvm i 6

I'm not sure whether it's nvm or my environment issue. Any help is appreciated. Thanks!

Would you like to give us your nvm debug result?

Okay, so looks like there is something broken, may be sed usage.
Any additional package management tool installed? Like MacPorts or homebrew.

@PeterDaveHello thanks for taking a look, just figured that out.
I just didn't copy the second line of the instruction

 export NVM_DIR="$HOME/.nvm"
  . "/usr/local/opt/nvm/nvm.sh"

Now it works great. Anyway, thanks for the quick help! Closing the issue.
