Installation Node v4.1 with NVM - Permission denied - node.js

Question

I have to install Node v4.1.x on Ubuntu. I have already installed it but with the wrong version. This are the steps that I followed untill now:
Installation of nvm
sudo git clone https://github.com/creationix/nvm.git /opt/nvm
sudo mkdir /usr/local/nvm
sudo addgroup -system dev
sudo chown -R root:dev /usr/local/nvm
sudo chmod -R 775 /usr/local/nvm
sudo vim /etc/profile.d/nvm.sh
Editing of the file
export NVM_DIR=/usr/local/nvm
source /opt/nvm/nvm.sh
export NPM_CONFIG_PREFIX=/usr/local/node
export PATH="/usr/local/node/bin:$PATH"
Installation of Node
sudo mkdir /usr/local/node
sudo chown -R root:dev /usr/local/node
sudo chmod -R 775 /usr/local/node
nvm stable
For installing node v4.1.x this is what I want to do:
nvm ls //list of all version
nvm use 4.1.x //if I find the correct version in the list
The problem is that I can't make nvm ls because I get
mkdir: cannot create directory ‘/usr/local/nvm/alias’: Permission denied
What can I do?

Answer 1

I think you might change NVM_DIR to:
NVM_DIR="$HOME/.nvm"

Answer 2

The problem is that you've installed nvm using root user (with sudo). When executing nvm commands later:
nvm ls
nvm use 4.1.x
you do this without root and you get a permission denied.
Generally it is not recommended to install nvm using super user.

This can also be because of issues during the curl installation.
Try reinstalling using
sudo apt-get install build-essential libssl-dev curl git-core

Answer 4

In your case issue because you gave 755 permission to the nvm folder. So it cant create folder without write permission as non root user.
Solution is you should be a root user or else give write permission for the folder to your particular user.
I too faced the same issue while installing nvm
ubuntu#ip-10-0-0-94:~$ nvm install 6.0.0
It reported as,
nvm install 6.0.0 mkdir: cannot create directory ‘/home/ubuntu/.nvm/bin’: Permission denied
grep: /home/ubuntu/.nvm/bin/node-v6.0.0-linux-x64/node-v6.0.0-linux-x64.tar.xz: No such file or directory Binary download failed
It with the 755 permission before.
drwxr-xr-x 4 root root 4096 Jun 23 07:44 .nvm/
Then I just gave write permission for it.
sudo chmod +w .nvm
Now issue was resolved and working fine.
ubuntu#ip-10-0-0-94:~$ nvm install 6.0.0
