Fix EINVAL error when running npm commands on Windows in GitHub Actions

[oke-py]

test-on-windows failed. https://github.com/oke-py/npm-audit-action/actions/runs/14787183713/job/41517583398

The failure is occurring because of the error: spawnSync npm.cmd EINVAL. This typically happens when the command npm.cmd is not recognized or cannot be run correctly in the environment. Here's the analysis and solution:

Problem Analysis

1. Error Details:
   • The error spawnSync npm.cmd EINVAL indicates that the npm command could not be executed properly in the Windows environment.
2. Job Configuration:
   • The failing job is running in windows-latest (build-on-windows or test-on-windows steps).
   • The relevant step is:

     - name: Install dependencies and run all scripts
       run: |
         npm ci
         npm run all
     

3. Possible Causes:
   • npm is not properly installed or configured in the Windows environment.
   • The npm.cmd file is missing or not accessible in the PATH.
4. Environment Setup:
   • The workflow uses actions/setup-node@v4 to set up Node.js, which should include npm.
   • However, there might be a misconfiguration or a missing PATH update in the environment.

Solution

To resolve the issue, ensure that npm is correctly set up and accessible. Update the workflow file as follows:

Updated Workflow

- name: Ensure npm is installed and accessible
  run: |
    echo "Verifying npm installation..."
    npm --version
    node --version

Add this step right after actions/setup-node@v4 to verify that npm and node are correctly installed.

Debugging the PATH

If npm is still not recognized, explicitly add its location to the PATH. Update the workflow as follows:

- name: Fix npm PATH issue on Windows
  if: runner.os == 'Windows'
  run: |
    echo "Fixing npm PATH..."
    SET PATH=%APPDATA%\npm;%PATH%

Retry Dependency Installation

If the above steps fix the issue, the npm ci and npm run all commands should succeed. Ensure these commands are rerun:

- name: Re-run Install dependencies and scripts
  run: |
    npm ci
    npm run all

Validation

After applying the fix, re-run the workflow and verify that the job completes without the EINVAL error.
