@wandyirawan I think this issue is specific to the nodejs plugin so I have transferred it to the asdf-nodejs repo issue tracker.

@augustobmoura this bug doesn't look familiar to me, so I was wondering if you thought this might have anything to do with the recent PRs.

I'm having the same problem. Also using Manjaro Linux and asdf v0.8.1

My ~/.tool-versions:

nodejs 14.18.0

When running asdf install

The following message is displayed:
mkdir: cannot create directory ‘/opt/asdf-vm/tmp’: Permission denied

I am writing to confirm that I am experiencing the same error on Arch Linux. Here are details about my operating system:

Linux  5.15.10-arch1-1 #1 SMP PREEMPT Fri, 17 Dec 2021 11:17:37 +0000 x86_64 GNU/Linux

Here is the version of asdf that I am currently running:

v0.8.1

I typed the following command that I found from the README file:

asdf plugin add nodejs https://github.com/asdf-vm/asdf-nodejs.git

If I type the command asdf list all nodejs I see the following error in my terminal window:

mkdir: cannot create directory ‘/opt/asdf-vm/tmp’: Permission denied

Thanks for your work on this plugin for asdf! If you have any feedback on how to resolve this issue, it would be greatly appreciated!

Hmm, I think I know what is going on. It was actually a "bugfix" that made this current bug surface. If you look on commit 800e244, on file lib/utils.sh existed a typo, we were fallbacking ASDF_DATA_DIR to ASDF_HOME, the problem is that ASDF_HOME doesn't exist anywhere, the correct name for the variable is ASDF_DIR, so the current bug was not reached in the past:

+ export ASDF_NODEJS_CACHE_DIR="${ASDF_DATA_DIR:-${ASDF_DIR:-$HOME/.asdf}}/tmp/$ASDF_NODEJS_PLUGIN_NAME/cache"

# ...

- versions_cache_dir="${ASDF_DATA_DIR:-${ASDF_HOME:-$HOME/.asdf}}/tmp/$(plugin_name)/cache"
+ versions_cache_dir="$ASDF_NODEJS_CACHE_DIR/versions-tab"

We should never use ASDF_DIR in this case. asdf-core doesn't use ASDF_DIR when resolving the directory for installing new plugins/versions, neither should we use it for our cache.

I will open a new PR fixing this, and some other issues that will probably arise from this discrepancy between our logic and asdf-core

From what I understand from http://asdf-vm.com/manage/configuration.html#environment-variables, ASDF_NODEJS_CACHE_DIR should be inside ASDF_DATA_DIR, falling back directly to ~/.asdf if ASDF_DATA_DIR is not set, something like:

export ASDF_NODEJS_CACHE_DIR="${ASDF_DATA_DIR:-$HOME/.asdf}/tmp/$ASDF_NODEJS_PLUGIN_NAME/cache"

Yes, that is right, it should not fallback to ASDF_DIR at all

[augustobmoura]

Check if that solves the issue. If it doesn't, we reopen the issue

That fixed it for me. Thank you @augustobmoura <3

Hello @augustobmoura, thanks for your efforts in fixing this defect. I am writing to confirm that this fix works for me and I am now able to use asdf to install NodeJS. I have tried multiple commands and they all seem to work correctly now! Thanks!
