node.js - with - nvmrc




nvm keeps “forgetting” node in new terminal session (8)

Alias to node itself to avoid updating the default alias along with node version updates later on.

nvm alias default node

Upon using a new terminal session in OS X, nvm forgets the node version and defaults to nothing:

$ nvm ls:

         .nvm
     v0.11.12
     v0.11.13

I have to keep hitting nvm use v.0.11.13 in every session:

         .nvm
     v0.11.12
->   v0.11.13

I've tried both the brew install, as well as the official installation script.

My .profile for the brew version:

#nvm
export NVM_DIR=~/.nvm
source $(brew --prefix nvm)/nvm.sh

And for the install.sh script:

$ curl https://raw.githubusercontent.com/creationix/nvm/v0.10.0/install.sh | bash

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

Any clue to what I'm doing wrong?


Also in case you had node installed before nvm check in your ~/.bash_profile to not have something like :

export PATH=/bin:/sbin:/usr/bin:/usr/local/sbin:/usr/local/bin:$PATH

If you do have it, comment/remove it and nvm should start handling the default node version.


If you have tried everything still no luck you can try this :_

1 -> Uninstall NVM

rm -rf ~/.nvm

2 -> Remove npm dependencies by following this

3 -> Install NVM

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

4 -> Set ~/.bash_profile configuration

Run sudo nano ~/.bash_profile

Copy and paste following this

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

5 -> CONTROL + X save the changes

6 -> Run . ~/.bash_profile

7 -> Now you should have nvm installed on your machine, to install node run nvm install v7.8.0 this will be default node version or you can install any version of node


In my case, another program had added PATH changes to .bashrc

If the other program changed the PATH after nvm's initialisation, then nvm's PATH changes would be forgotten, and we would get the system node on our PATH (or no node).

The solution was to move the nvm setup to the bottom of .bashrc

### BAD .bashrc ###

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

# Some other program adding to the PATH:
export PATH="$ANT_ROOT:$PATH"

Solution:

### GOOD .bashrc ###

# Some other program adding to the PATH:
export PATH="$ANT_ROOT:$PATH"

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

(This was with bash 4.2.46 on CentOS. It seems to me like a bug in bash, but I may be mistaken.)


This question has mentioned for the OSX, but it happened to me in my linux OS. I tried using nvm alias default <version> but for each new terminal session the used node version was forgotten. so, here is the solution that i figured out.

make sure to set a default alias for node version,put the following code in .bashrc, and source .bashrc.

export NVM_DIR="/home/bonnie/.nvm"
## If the file exists and is not empty
if [ -s "$NVM_DIR/nvm.sh" ]; then
    ## Source it
    source "$NVM_DIR/nvm.sh"
fi
NODE_DEFAULT_VERSION=$(<"$NVM_DIR/alias/default")
export PATH="$NVM_DIR/versions/node/$NODE_DEFAULT_VERSION/bin":$PATH

To install the latest stable version:

nvm install stable

To set default to the stable version (instead of a specific version):

nvm alias default stable

To list installed versions:

nvm list

As of v6.2.0, it will look something like:

$ nvm list
         v4.4.2
->       v6.2.0
default -> stable (-> v6.2.0)
node -> stable (-> v6.2.0) (default)
stable -> 6.2 (-> v6.2.0) (default)
iojs -> N/A (default)

nvm does its job by changing the PATH variable, so you need to make sure you aren't somehow changing your PATH to something else after sourcing the nvm.sh script.

In my case, nvm.sh was being called in .bashrc but then the PATH variable was getting updated in .bash_profile which caused my session to find the system node before the nvm node.


run this after you installed any version,

n=$(which node);n=${n%/bin/node}; chmod -R 755 $n/bin/*; sudo cp -r $n/{bin,lib,share} /usr/local

This command is copying whatever version of node you have active via nvm into the /usr/local/ directory and setting the permissions so that all users can access them.
