fix(install): preflight Node.js and npm prerequisites in install.ps1#3042wzc1753 wants to merge 4 commits into
Conversation
- Check for Node.js presence and major version (>= 18) before invoking installer - Check for npm presence when node_modules is missing during git-clone installs - Use [Console]::Error.WriteLine to ensure clean stderr output and preserve exit codes - Add regression tests in tests/scripts/install-ps1.test.js covering missing and outdated Node.js environments
📝 SummarySummary by CodeRabbit
WalkthroughThe installer now requires Node.js 18 or newer and checks npm before dependency installation. The test harness controls child-process PATH values and covers missing, unsupported, and invalid Node.js versions. ChangesInstaller preflight validation
Priority: ➖ Normal Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The installer adds Node.js and npm prerequisite checks, but malformed or extreme version output may not follow the intended actionable failure path, and some isolated-PATH tests can fail before the installer runs. These issues should be addressed before merging to preserve reliable prerequisite diagnostics and coverage. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

🟡 Changes recommended
The Node.js version preflight currently doesn’t fail closed when the version string can’t be determined/parsed (and there are a couple of small quality issues to address in the touched regions).
Once you've addressed the issues Copilot identified, you can request another Copilot review.
Pull request overview
This PR hardens the Windows install.ps1 entrypoint by adding early, user-friendly preflight checks for Node.js/npm prerequisites and adds regression tests to ensure the preflight behavior is stable (especially under PATH isolation).
Changes:
- Add PowerShell preflight checks for Node.js presence and minimum major version (>= 18), plus npm presence when
node_modulesis missing. - Replace
Write-Errorwith[Console]::Error.WriteLine+ explicitexitto avoid noisy terminating error stack traces under$ErrorActionPreference = 'Stop'. - Extend
tests/scripts/install-ps1.test.jswith new unit/regression tests for “missing Node” and “Node < 18”, and improve PowerShell binary path resolution + env isolation.
File summaries
| File | Description |
|---|---|
| install.ps1 | Adds Node.js/npm preflight checks and switches error emission to stderr + explicit exit codes. |
| tests/scripts/install-ps1.test.js | Adds preflight-focused tests and hardens PowerShell resolution + PATH isolation handling. |

Addressed in 5c78d38. The child environment is now constructed immutably using Object.fromEntries without mutating the base environment in place.

In `@install.ps1`:
- Line 44: Update the Node.js version validation in install.ps1 to reject output
that does not match the expected version format before comparing the parsed
major version, emitting a clear error for unparseable values. Preserve rejection
of supported-format versions below 18, and add a regression test using a mock
node executable that outputs an invalid version string.
- Around line 44-45: Define a single $minimumNodeMajor value near the Node.js
version validation, then use it for both the version comparison and the error
message in the validation block. Remove the duplicated hardcoded minimum version
while preserving the existing requirement and reporting behavior.
In `@tests/scripts/install-ps1.test.js`:
- Line 82: Update the environment-building logic around the delete and
assignment operations to avoid mutating env. Create a new object for each
overridden environment, including the case-insensitive PATH replacement, while
preserving the existing variable overrides and values.
- Line 221: Define a single UNSUPPORTED_NODE_VERSION constant in the test and
reuse it in both the mocked node.cmd output and the expected error assertions,
including the related occurrences at the referenced test cases; remove the
duplicated hardcoded version values.

The `tests/run-all.js` aggregator parses these tokens from combined stdout and stderr, so a combined line such as `Results: Passed: N, Failed: N` is sufficient; do not require separate `Passed: N` and `Failed: N` lines.

Validate the complete Node.js version string.
The regex accepts v18.invalid because it checks only the major component and the first dot. The script then accepts the version and continues to dependency installation and install-apply.js.
Require a complete version before reading the major group. Add v18.invalid to the regression test.

tests/scripts/install-ps1.test.js:310
If PowerShell and npm are installed in the same directory, adding `path.dirname(powerShellCommand)` to this isolated `PATH` makes `Get-Command npm` find the real npm. The fixture then runs a real install instead of testing the missing-npm branch, making this regression test environment-dependent. PowerShell is already invoked by its absolute path, so its directory does not need to be exposed to the child process.

There was a problem hiding this comment.
The new missing-npm branch and the changed nonzero npm install handling have no regression tests. The installer test file only adds Node.js prerequisite cases, so a future change can break npm error messaging, location cleanup, or exit-code propagation without detection. This is non-blocking, but it increases the cost of safely maintaining installer failure behavior.
Knowledge Base Used: Installer orchestration
Artifacts
- The authored Bash driver creates a base worktree, executes the same install.ps1 test scope before and after the PR, and captures the test output and npm-path references; it shows the exact executable validation method.
- The base revision's `node tests/scripts/install-ps1.test.js` output passes two static tests and skips PowerShell-dependent tests because PowerShell is unavailable; it establishes the before comparison.
- The PR revision's `node tests/scripts/install-ps1.test.js` output again passes only two static tests and skips all PowerShell tests, then lists production npm branches and the absence of matching harness tests; it demonstrates the stated coverage gap while direct runtime exercise is blocked.
- The command driver completion log records the executed script, working directory, exit code, and before/after capture paths; it confirms the comparison captures were produced.

45-45: Reject incomplete Node.js version output.This remains the same unresolved issue from the previous review. The regex accepts
v18.invalidbecause it checks only the major component and the first dot. Require a complete version before comparing the major version. Add a regression case forv18.invalid.
2-2: LGTM!Also applies to: 38-42, 58-61, 65-67

If PowerShell and npm are installed in the same directory, adding path.dirname(powerShellCommand) to this isolated PATH makes Get-Command npm find the real npm. The fixture then runs a real install instead of testing the missing-npm branch, making this regression test environment-dependent. PowerShell is already invoked by its absolute path, so its directory does not need to be exposed to the child process.

Comment:
**PATH isolation exposes npm**
If PowerShell and npm are installed in the same directory, adding `path.dirname(powerShellCommand)` to this isolated `PATH` makes `Get-Command npm` find the real npm. The fixture then runs a real install instead of testing the missing-npm branch, making this regression test environment-dependent. PowerShell is already invoked by its absolute path, so its directory does not need to be exposed to the child process.

What Changed
install.ps1:Get-Command node -ErrorAction SilentlyContinue).node -vparsing) aligned withpackage.json"engines".npmpresence when installing from a git clone lackingnode_modules.[Console]::Error.WriteLine+ explicitexitcodes to preserve process exit codes and prevent noisy PowerShellActionPreferenceStopExceptionstack traces under$ErrorActionPreference = 'Stop'.tests/scripts/install-ps1.test.js:v16.20.0).fs.realpathSync.nativeand isolated PATH fixtures across platforms.Why This Change
On Windows systems, running
install.ps1without Node.js or with an unsupported Node version (< 18) previously resulted in raw PowerShell terminating exceptions (e.g.npm: The term 'npm' is not recognizedor syntax errors inside modern JavaScript runtime) without clear guidance for the user. These preflight checks fail fast with actionable instructions and official download URLs before any target directory or configuration is mutated.Testing Done
