Sourcing nvm-wrapper doesn't work on OS X

[taktran]

I tried putting this in my ~/.config/fish/config.fish:

source ~/.config/fish/nvm-wrapper/nvm.fish

But when I start a new terminal I get

N/A: version "default" is not yet installed

Also, when I do nvm --version, I get

/var/folders/38/yjtncyws5617fdmj7xkp41yc0000gn/T/nvm-wrapper.7S63h74P/oldenv: line 1: 15:PATH=/usr/local/Cellar/coreutils/8.23_1/libexec/gnubin:/usr/local/share/npm/bin:/Users/[user]/bin/AWS-ElasticBeanstalk-CLI-2.6.3/eb/macosx/python2.7/:/Users/[user]/Library/Android/sdk/tools:/Users/[user]/Library/Android/sdk/platform-tools:/Users/[user]/.rbenv/shims:/Users/[user]/.rbenv/bin:/usr/local/bin:/usr/local/heroku/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin: No such file or directory

Did I do something stupid with my PATH?

nvm does work when I use bash though.

Sigh. I need to put up a big warning: _"Not tested with OS X"_

I can't debug your issue, I don't have a Mac. If you find a fix, please please submit a PR or send me a diff or patch, and I'll test it on Linux and see what can be done. Sorry I can't be more helpful.

May be related to #7

@taktran have you tried setting the default node version with nvm?

[taktran]

@jkarttunen I can't set a default node version because, none of the nvm commands work when I'm in fishfish

Is #7 solved @passcod ?

[passcod]

@taktran Nope. Your best bet is to drop into bash, source nvm, install a node and set the default, and try again, see if it works.

@taktran I have the same problem with "N/A: version "default" is not yet installed" though no path issue (on quite a fresh Yosemite 10.10.3, nvm installed via brew).

$ . nvm-wrapper/nvm.fish
N/A: version "default" is not yet installed
$ nvm alias default v0.10
! WARNING: Version 'v0.10' does not exist.
default -> v0.10 (-> N/A)
$ nvm install v0.10
N/A: version "v0.10" is not yet installed  # huh?!
$  nvm ls
N/A: version "v0.10" is not yet installed

So something is, excuse me, fishy here. I need to investigate more.

UPDATE There is clearly some conflict between fish and bash nvm/variables (I've orignally used the bash nvm to install a node version). When I start bash from fish, i.e. inheriting some fish env variables:

fish$ bash
bash-3.2$ nvm ls
bash: nvm: command not found
bash-3.2$ source /usr/local/opt/nvm/nvm.sh
N/A: version "v0.10" is not yet installed               # <-- notice the same error
bash-3.2$ nvm ls

->       system
default -> v0.10 (-> N/A)
node -> stable (-> N/A) (default)
iojs -> iojs- (-> N/A) (default)
bash-3.2$ nvm install v0.10
v0.10.38 is already installed.
Now using node v0.10.38

However when I start a fresh bash as a login shell, not from fish, nvm works there flawlessly.

Here are some important differences:

login bash$ env | grep NVM
NVM_PATH=/Users/me/.nvm/v0.10.38/lib/node
NVM_DIR=/Users/me/.nvm
NVM_BIN=/Users/me/.nvm/v0.10.38/bin

bash from fish after sourcing nvm.sh there$ env | grep NVM
NVM_PATH=/usr/local/opt/nvm/v0.10.38/lib/node
NVMSH=/usr/local/opt/nvm/nvm.sh
NVM_DIR=/usr/local/opt/nvm
NVM_BIN=/usr/local/opt/nvm/v0.10.38/bin

See the difference ~/.nvm versus /usr/local/opt/nvm? That is our hint.

Good night and hopefully I find out more tomorrow.

[holyjak]

Uh, sorry, ignore the env var differences - that was due to me trying to help nvm.fish find nvm.sh by adding this:

if test -f (brew --prefix nvm)/nvm.sh
   set -x NVMSH (brew --prefix nvm)/nvm.sh
else
  set -x NVMSH ~/.nvm/nvm.sh
end

[passcod]

Still, great work there @jakubholynet — hopefully you'll find additional hints pointing to an eventual solution!

Update:

fish$ env | egrep 'nvm|NVM'
fish$ bash -c "source /usr/local/opt/nvm/nvm.sh"
N/A: version "v0.10" is not yet installed
fish$ bash -lc "source /usr/local/opt/nvm/nvm.sh"
fish$

So I do not have any NVM variables set but sourcing nvm.sh from bash still fails. But if I source it as a login shell, it succeeds. (Sourcing from within bash, i.e. bash$ bash -c "source /usr/local/opt/nvm/nvm.sh" works correctly as well.) So there is something fishy about fish but I do not know what (BTW have not sourced nvm.fish in the fish shell I have used above.)

It looks like nvm.sh remembers correctly that I have aliased v0.10 as my default but somehow cannot find it when run from fish. Perhaps it looks at a different path?!

Any further troubleshooting ideas?

\UPDATE: The difference with -l is that nvm.sh is sourced once - and presumably the first sourcing sets things up right so the next one (the only one run when exec without -l) does not fail.

When I add some logging to nvm.sh:

fish$ bash -lc "source /usr/local/opt/nvm/nvm.sh"; cat /tmp/log
nvm_alias(default): looking at alias path /Users/me/.nvm/alias/default
fish$ bash -c "source /usr/local/opt/nvm/nvm.sh"; cat /tmp/log
N/A: version "v0.10" is not yet installed
nvm_alias(v0.10): looking at alias path /usr/local/opt/nvm/alias/v0.10

So the bash-only nvm looks at aliases in ~/.nvm/alias/ while under fish it looks into /usr/local/opt/nvm/alias/ (and there is no v0.10 in any of the two)

FIXED: By adding set -x NVM_DIR ~/.nvm prior to sourcing nvm.fish, I got rid of the error.

The problem is that nvm tries to guess its dir from the location of the nvm.sh script, which does not work as expected when the script is under brew. When nvm.sh was installed, brew has recommended to put both setting NVM_DIR and sourcing nvm into ~/.profile.
