have NVM_PATH correct value?

[marcelino-m]

NVM_PATH has value

/home/$USER/.nvm/versions/node/YOUR_NODE_VERSION/lib/node

but this file not exist, Is that correct?

Cheers

NVM_PATH is just an internal variable; it should be local and not exposed (359a83e)

What does nvm ls and nvm debug output? Is there an actual problem you're experiencing, or are you simply wondering about the contents of this env var?

[marcelino-m]

I need to detect current version of node in my editor, so I look this variable for track this and find correct node_module/,
but I have to add a "../" string in path to use NVM_PATH

;; elisp code
 (concat (getenv "NVM_PATH")
               "/../node_modules/tern/emacs/")

Which would be a suitable way to find the folder node_module/ for the current version of node?

Cheers!

Use nvm current to get the current version of node, if you have a shell environment.

Ok, I am wondering now if is correct that value of NVM_PATH:

ls $NVM_PATH

result is :

ls: cannot access '/home/marcelo/.nvm/versions/node/v7.2.1/lib/node': No such file or directory 

nvm ls:

->       v7.2.1
default -> v7.2.1
node -> stable (-> v7.2.1) (default)
stable -> 7.2 (-> v7.2.1) (default)
iojs -> N/A (default)
lts/* -> lts/boron (-> N/A)
lts/argon -> v4.7.0 (-> N/A)
lts/boron -> v6.9.2 (-> N/A)

And nvm debug

nvm --version: v0.32.1
$SHELL: /bin/bash
$HOME: /home/marcelo
$NVM_DIR: '$HOME/.nvm'
$PREFIX: ''
$NPM_CONFIG_PREFIX: ''
nvm current: v7.2.1
which node: $NVM_DIR/versions/node/v7.2.1/bin/node
which iojs: 
which npm: $NVM_DIR/versions/node/v7.2.1/bin/npm
npm config get prefix: $NVM_DIR/versions/node/v7.2.1
npm root -g: $NVM_DIR/versions/node/v7.2.1/lib/node_modules

Cheers!

That doesn't seem correct - i'd expect node_modules at the end.

That said, nothing uses NVM_PATH so it doesn't really matter if it's broken - npm root -g should give you what you want.

[ljharb]

I've removed $NVM_PATH entirely from the next version of nvm, so nobody's confused about it.

[marcelino-m]

Ok!

[XadillaX]

So how can I use this env?

It's used in my VIM rc.

[XadillaX]

let g:node_include_path = fnamemodify(
            \ fnamemodify($NVM_PATH, ':h'),
            \ ':h')
let g:syntastic_cpp_include_dirs = [
            \ g:node_include_path . '/include/node',
            \ g:node_include_path . '/lib/node_modules/nan',
            \...]

[ljharb]

@XadillaX no idea what TNVM_PATH is, and NVM_PATH no longer exists; try npm root -g.

[XadillaX]

So any environment variable to describe current Node.js version's root? e.g.

/Users/.../.nvm/versions/node/v8.9.2

Because the newest version break my VIM configuration.

[ljharb]

No, there aren’t. Just a command: npm root -g or `which node etc
