Vite Plus PATH shim can shadow external CLI upgrades (OpenCode example)

まず opencode --version と opencode upgrade --print-logs を使って Windows PowerShell のケースを再現し、次に Vite Plus が実行ファイルを ~/.vite-plus/bin に配置する方法と、PATH がそれらを解決する方法を調査します。外部アップグレードが成功した後、手動で置き換えなくても通常の opencode コマンドで新しくインストールされたバージョンが実行されれば完了です。ほかのケースが確認されない限り、OpenCode に関して示されている範囲を維持してください。

Summary

On Windows, a Vite Plus-owned executable in ~\.vite-plus\bin can remain ahead of a newer version installed by that CLI's own updater. The shell command then continues to run the stale Vite Plus executable.

OpenCode is the confirmed example below. This may affect any externally updatable CLI for which Vite Plus installs an executable with the same command name, but this report does not claim other packages are currently affected.

Environment

• Windows
• Vite Plus: 0.2.4
• OpenCode before upgrade: 1.17.18

Reproduction

opencode --version
# 1.17.18

opencode upgrade --print-logs

The updater reported:

Using method: npm
From 1.17.18 → 1.18.1
Upgrade complete

But immediately afterwards:

opencode --version
# 1.17.18

Investigation

The command resolved to the Vite Plus-owned path:

C:\Users\<user>\.vite-plus\bin\opencode.exe

The updater had installed OpenCode 1.18.1 at:

C:\Users\<user>\.vite-plus\js_runtime\node\22.19.0\node_modules\opencode-ai\bin\opencode.exe

Running that executable directly returned 1.18.1; the PATH executable remained at 1.17.18.

Scope checked

• Confirmed: opencode was shadowed by the stale Vite Plus executable.
• Not implicated in this installation: npm, npx, and corepack resolve to NVM rather than ~\.vite-plus\bin.
• Potentially affected pattern: any CLI that manages its own upgrades while Vite Plus also places a same-named executable earlier on PATH.

Expected behavior

After a CLI reports a successful self-upgrade, its normal shell command should run the upgraded version.

Workaround

Replacing the stale Vite Plus executable with the newly installed OpenCode executable made opencode --version report 1.18.1.

Suggested direction

Vite Plus could avoid installing static, same-named binaries for externally self-updating CLIs, make them forwarding shims, or provide a way to refresh the Vite Plus bin entry after an external upgrade.
