Remote provisioning fails on fresh hosts without Node (bootstrap exits 2 in nodePathPrelude) #20

Plugin version

0.8.18

DSH version

Local: 0.2.2-rc.1 (DSH Desktop, Windows 11). Remote: fresh Ubuntu 24.04, no Node installed.

Area

Remote provisioning

Reproduction steps

1. Install dsh-remote-local-plugin@0.8.18 (desktop profile) and restart.
2. Add an SSH host that has no Node.js installed (the auto-install-Node path).
3. Let auto-connect run provisioning. The agent tarball is uploaded and ~/.local/share/dsh-remote / ~/.dsh/remote-agent are created, then provisioning fails and retries with:

远端自动安装失败：remote bootstrap exited with 2

Expected behavior

Bootstrap detects the missing Node and installs the configured remoteNodeVersion (22.19.0 by default), then continues.

Relevant logs

Root cause appears to be nodePathPrelude() in the generated bootstrap script. It runs under set -euo pipefail and contains:

NODE_BIN_DIR="$(ls -d "$HOME"/.nvm/versions/node/*/bin 2>/dev/null | sort -V | tail -1)"

On a host without nvm, the glob does not match, ls exits 2, and pipefail makes the whole script exit 2 before the Node-install step. Reproduced standalone by running the prelude on the remote host: PRELUDE_EXIT=2.

Workaround: install Node 22.19.0 on the remote host first; provisioning then completes in ~30s.

Possible fix: append || true to the ls ... | sort -V | tail -1 pipeline (or guard with compgen -G before listing).
