install command can fail if run at the same time in multiple terminals

Well, I've never encountered this particular issue, but I suppose anything is possible. Maybe you stumbled upon some extremely rare edge case that only a select few have ever experienced. Or maybe it's just the limitations of Fish's subpar concurrency. I may circle back to this later, but I'll keep it closed for now.

I see. But you still should be able to use multiple nodes at the same time in different terminals, since path changes are local, yes?

Yes I can, but when this happens the terminal in which the failure happened will have the Homebrew node in the path until I re-run activate_directory_node_version:

awk: can't open file /Users/grant/.local/share/nvm/.index.temp
 source line number 6
nvm: Invalid version number or alias: "18.14.2"
Welcome to fish, the friendly interactive shell
Type `help` for instructions on how to use fish
~/c/a/s/web> node --version
v19.6.1
~/c/a/s/web> which node
/usr/local/bin/node
~/c/a/s/web> activate_directory_node_version
Now using Node v18.14.2 (npm 9.5.0) ~/.local/share/nvm/v18.14.2/bin/node
~/c/a/s/web> node --version
v18.14.2
~/c/a/s/web> which node
/Users/grant/.local/share/nvm/v18.14.2/bin/node

While the other terminal will (correctly) have the NVM node in the path from the beginning:

Now using Node v18.14.2 (npm 9.5.0) ~/.local/share/nvm/v18.14.2/bin/node

To clarify, this only happens within VS Code?

To clarify, this only happens within VS Code?

It happens in VS Code but it’s not a VS Code-specific bug.

I can also trigger this by opening two Terminal.app tabs to directories containing .node-version files, saving them with “Window -> Save Windows as Group…”, then opening that group with “Window -> Open Window Group” (might not happen every time, but happened for me in 2/3 attempts). So I think it’s safe to say this can happen in any context where nvm install is called simultaneously in two or more terminals.

May I ask why you are trying to run the install command simultaneously in multiple terminals? Given that this is outside the scope of the project, I am going to close this issue (at least for now).

I’ll often have two terminal tabs open in VS Code, and when I reopen the project they’re restored simultaneously.

I understand this is an unusual use case — for now I’ve been using fnm to solve this. Thanks for this project, it’s served me well for years!
