`pnpm self-update <version>` writes the target binary to
`${PNPM_HOME}/bin/`, leaving the bootstrap symlink at `${PNPM_HOME}/pnpm`
untouched. The `bin_dest` output was set to `${PNPM_HOME}`, so consumers
invoking `${{ steps.pnpm.outputs.bin_dest }}/pnpm` got the bootstrap
version (currently 11.0.4) instead of the version they requested.
PATH lookup hid the bug: `${PNPM_HOME}/bin` was prepended ahead of
`${PNPM_HOME}`, so `pnpm` resolved from PATH was the right one. Existing
version-respect tests only checked `pnpm --version`, not `bin_dest`.
Resolve `binDest` inside `runSelfInstaller` (target lives in
`${PNPM_HOME}/bin` after self-update, otherwise stays at `${PNPM_HOME}`)
and plumb it through to `setOutputs`. Add a regression test that invokes
`${bin_dest}/pnpm --version` directly across Linux/macOS/Windows.
* fix: overwrite npm .cmd wrappers for @pnpm/exe on Windows
npm creates .cmd wrappers that invoke bin entries through `node`,
but @pnpm/exe bins are native executables, not JavaScript files.
This causes pnpm commands to silently fail on Windows.
* fix: copy pnpm.exe to .bin/ on Windows for standalone mode
The .cmd wrapper approach didn't work because CMD doesn't properly
wait for extensionless PE binaries. Instead, copy the actual .exe
(and .cmd for pnpx) from @pnpm/exe into .bin/ so PATHEXT finds
pnpm.exe directly, bypassing npm's broken node-wrapping shim.
* fix: add @pnpm/exe dir to PATH on Windows instead of .bin shims
On Windows, npm's .bin shims can't properly execute the extensionless
native binaries from @pnpm/exe. Instead of trying to fix the shims,
add the @pnpm/exe directory directly to PATH where pnpm.exe lives.
* test: validate pnpm --version output in CI
All version checks now capture output and assert it matches a semver
pattern. Previously, a silently failing pnpm (exit 0, no output)
would pass the tests.
* debug: log pnpm --version output during setup
* fix: remove duplicate addPath in setOutputs that shadowed pnpm.exe
setOutputs called addPath(node_modules/.bin) AFTER installPnpm had
already added the correct path (@pnpm/exe on Windows). Since
GITHUB_PATH entries are prepended, .bin ended up first in PATH,
causing PowerShell to find npm's broken shims instead of pnpm.exe.
* fix: add PNPM_HOME/bin to PATH on all platforms
* fix: address review feedback — PATH ordering and regex anchoring
- Swap addPath order so pnpmHome (with pnpm.exe) is prepended last
and has highest precedence over pnpmHome/bin.
- Anchor version regex with $ and allow prerelease suffixes.
