Mismatch node version

[LasyIsLazy]

After volta install node@18.10.0

➜  ~ volta list
⚡️ Currently active tools:

    Node: v18.10.0 (default)
    Tool binaries available:
        pnpm, pnpx (default)

See options for more detailed reports by running `volta list --help`.
➜  ~ node -v
v14.20.0
➜  ~ whereis node
node: /Users/xx/.volta/tools/image/node/14.20.0/bin/node /Users/xxx/.volta/tools/image/node/14.20.0/share/man/man1/node.1

The volta list command shows that the node version is 18.10.0, but the node -v command tells me the version is 14.20.

It's confusing.

Hi @LasyIsLazy, that is confusing! It looks like your PATH is including the internal Volta path to a specific Node version, rather than the Volta shims (that actually handle the resolution). That shouldn't normally be happening, is this possibly in a sub-shell or something that was itself spawned from Node? Can you share the output of echo $PATH and if possible any lines in your shell startup script (e.g. .zshrc, .bash_profile, .bashrc, or similar) that reference Volta?

@LasyIsLazy Thanks for sharing! I think I see the issue: The last line in the .zshrc is adding the value of pnpm bin -g to the PATH. I did a Google translate on the comment for that line, so correct me if I'm misunderstanding, but I believe that exists to work around the issue that Volta doesn't fully support pnpm yet, so any packages globally installed (via pnpm i -g) aren't available?

The problem that comes up is that pnpm appears to be returning the path to the node binary (which presumably is also where they install global packages), so adding that to the PATH is forcing the Node version that pnpm uses to be first. Which then causes the original problem since that shadows the Volta shim that would normally allow for version switching.

Unfortunately, there isn't a great solution because of the overlap between the Node binary directory and pnpm's install. I can see a couple of potential workarounds:

1. Remove that last line and use volta install <package> instead of pnpm i -g <package> for your global installs. That will set up Volta to manage the globals, but has the downside of messing with your muscle memory / common patterns, which we try to avoid.
2. Wait for pnpm support to land in full in Volta. There's a PR out right now to add most of the support. The rest will need to be a follow-up, then we'll have a new release of Volta that adds the support. There isn't a firm timeline on that, however, so it's a short-term solution.

[LasyIsLazy]

@charlespierce Yes, you are right! After removed that line, it works!

In fact, I prefer to use pnpm to install global packages because pnpm is faster.

For me now, I have to use volta install or npm install to install global packages.

Anyway, thanks for your reply.

Just to add my experience regarding the exact same case (volta list + node -v):

I found out that the "node" bin stub was missing from $VOLTA_HOME/bin.
This is what it looked like when the node versions were reported differently:

.rwxr-xr-x   566 xxx 2022-11-03 08:38 eslint*
.rwxr-xr-x   564 xxx 2022-11-03 08:38 jsonlint*
.rwxr-xr-x   560 xxx 2022-11-03 08:38 pnpm*
.rwxr-xr-x   560 xxx 2022-11-03 08:38 pnpx*
.rwxr-xr-x   574 xxx 2022-11-03 08:38 prettier*
.rwxr-xr-x   562 xxx 2022-11-03 08:38 tsc*
.rwxr-xr-x   572 xxx 2022-11-03 08:38 tsserver*

I then ran volta setup --verbose and the result is this $VOLTA_HOME/bin:

.rwxr-xr-x   566 xxx 2022-11-03 08:38 eslint*
lrwxr-xr-x    44 xxx 2022-11-07 15:37 grunt -> /usr/local/Cellar/volta/1.1.0/bin/volta-shim*
.rwxr-xr-x   564 xxx 2022-11-03 08:38 jsonlint*
lrwxr-xr-x    44 xxx 2022-11-07 15:37 node -> /usr/local/Cellar/volta/1.1.0/bin/volta-shim*
lrwxr-xr-x    44 xxx 2022-11-07 15:37 npm -> /usr/local/Cellar/volta/1.1.0/bin/volta-shim*
lrwxr-xr-x    44 xxx 2022-11-07 15:37 npx -> /usr/local/Cellar/volta/1.1.0/bin/volta-shim*
.rwxr-xr-x   560 xxx 2022-11-03 08:38 pnpm*
.rwxr-xr-x   560 xxx 2022-11-03 08:38 pnpx*
.rwxr-xr-x   574 xxx 2022-11-03 08:38 prettier*
.rwxr-xr-x   562 xxx 2022-11-03 08:38 tsc*
.rwxr-xr-x   572 xxx 2022-11-03 08:38 tsserver*
lrwxr-xr-x    44 xxx 2022-11-07 15:37 yarn -> /usr/local/Cellar/volta/1.1.0/bin/volta-shim*

Now it works again (volta list === node -v). I assume installing it via homebrew and linking it to the "Cellar" version specific directory caused it?

I'm not sure though.

The actual link should perhaps be to /usr/local/bin/volta-shim and not directly to /usr/local/Cellar/volta/1.1.0/bin/volta-shim.
