n for each user?

[bigdx]

Hi,

My users (not su/root!) should be able to select their "own" node-version, for the current user (or current directory) only, NOT globally. Maybe I just messed up something, but I cant get that work. I have added "export N_PREFIX=$HOME" to .bash_profile and can install "local" (for current user) node-versions with "n VERSION" (to $HOME/n/version...), using "n" even switch them (without any error), but that has no effect at all: node -v still returns the same version (set by root)...

"n use ... -v" or "N_PREFIX=$HOME n use ... -v" (without export) seems to work so ...

What am I doing wrong?

[bigdx]

I installed n with the recommanded method "npm install -g n". OS is CentOS7. Globally n works like a charme...

I don't know how CentOS sets up the shell path. I know with Linux Mint and Ubuntu that .profile adds ~/bin to the front of the PATH if it is present. When running n from the user's home folder, it will install node/io to ~/bin.

Just make sure ~/bin is at the beginning of your PATH so it uses that node and not the version down in /usr. Where does it point when you run which node?

[bigdx]

$ which node
/usr/local/bin/node

I see, points to the "gobal" node. How do i change that so the "currently by n set" node-version is used?

/bin is included in the PATH (PATH=$PATH:$HOME/.local/bin:$HOME/bin) already, so thats not the problem.

There needs to be a "local n" , but how? With "npm install n"? After that
$ which n still points to /usr/bin/n

To which "bin" PATH has to point?

When you run echo $PATH ~/bin needs to be at the front of all other bin folders. It looks like your ~/bin is at the end?

Having N_PREFIX exported to $HOME for each user is correct. When n installs or activates a version, it will copy the node run time to bin folder under the directory of N_PREFIX.

Also, please keep you question to a single issue.

[bigdx]

Thx! Ok then, i'll try a differnt order of PATH, beginning with $HOME/bin ... where /bin does not exist yet ...

"Also, please keep you question to a single issue." Im not sure what you mean? My questions (as posts) in other issues (as threads) have nothing to do with each other ... at least I dont see any connection ... well, ok, all about n, right ^^ ... wouldn't be bad practice to mix different topics in one issue though? But maybe I just didn't get what you means ...

[ghost]

I saw your comments in other issues. They appeared to be asking the same as what you described in this issue. Sorry if I read it wrong.

[bigdx]

No Problem. But you are right in some way ... the problem all my questions based on, was in the end the same or at least related, but I didn't knew that at time of writing... Chicken/Egg-Problem at its best ^^

@bigdx Is your problem solved now?

[bigdx]

@maxrimue yes, solved (sorry, had some days off)

@tedgaydos Thx, changing the order of PATH worked. So if somebody has a similar problem, the .bash_profile looks somewhat like this now ...

$ nano ~/.bash_profile
   # ...

   # Changed PATH order, with §HOME/bin at the beginning, ahead of /usr/local/bin/
   PATH=$HOME/.local/bin:$HOME/bin:$PATH
   export PATH 

   # Add n prefix
   export N_PREFIX=$HOME

@bigdx Good, I'll close this now then
