nvm install command fails on FreeBSD

[honzahommer]

• Operating system and version:
  FreeBSD nvm 11.0-RELEASE-p9 FreeBSD 11.0-RELEASE-p9 #0: Tue Apr 11 08:48:40 UTC 2017 [email protected]:/usr/obj/usr/src/sys/GENERIC amd64, clean install on Vultr.com, run as root user.

• How did you install nvm? (e.g. install script in readme, homebrew):

$ wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.2/install.sh | bash
=> Downloading nvm from git to '/root/.nvm'

=> Appending nvm source string to /root/.profile
=> bash_completion source string already in /root/.profile
=> Close and reopen your terminal to start using nvm or run the following to use it now:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

• What steps did you perform?

$ nvm install v8.1.0

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH?

$ cat .profile

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm

• It looks, there is an issue with CC and CXX variables in nvm.sh. If I export these variables before installation, everything is OK.

$ export CC=cc  
$ export CXX=c++
$ nvm install v8.1.0

Now using node v8.1.0 (npm v5.0.3)

900, #1207, #130 may be relevant here.

These lines for FreeBSD set $CC to cc and $CXX to c++ if they're not otherwise set.

It looks like yours are already set to g++ and gcc respectively - what does which g++ and which gcc report?

[honzahommer]

which g++ and which gcc returns nothing.

[ljharb]

Sounds like that might be the problem - your CC and CXX vars are set to nonexistent compilers. If you unset CC CXX (or remove "setting them" from your profile files), I'd expect everything to work.

I ran into the same issue using nvm 0.33.11. Manually exporting CC=cc and CXX=c++ worked for me.
