Nvm: Unable to install 'Permission denied'

[danzimm]

I have run the install script and gotten the following error:

@danzimm What is the output of whoami? If you are nad, then you should have full ownership and permissions on anything within ~nad, including .nvm. If not, then since nvm is per-user, NVM_DIR should be unset before trying to run the install script.

[PeterDaveHello]

From the shell prompt, looks like @danzimm is using account dzimm on the environment, but nvm tried to install on nad's home, @danzimm can you provide the detail about the environment?

[ljharb]

@danzimm do you perhaps have nad or dzimm hardcoded in your profile files somewhere?

I am getting similar error

@suryaZivame what does nvm debug and whoami say?

This problem occurred to me as well. The problem was that I had imported my previous .bash_profile from my old machine. In it the file, I had export NVM_DIR="/Users/sghiassy/.nvm". On my new machine, my home directory was /Users/shaheen, and the conflicting user directory was causing the problem

The solution was to change the export to export NVM_DIR="$HOME/.nvm"

[danzimm]

Sorry for going dark - I can confirm the same thing that happened to @sghiassy happened to me. It looks like the nvm setup automatically adds export NVM_DIR="/path/to/home/.nvm" to your .bashrc. It seems like it should add export NVM_DIR="$HOME/.nvm" instead (it might be that $HOME isn't being escaped when that line is added and thus is being expanded at the time of setup).

[ljharb]

The problem is that we need the fully expanded path for the install script, so we'd need to parse out $HOME later in order to actually add that literal text into the profile file.
