Documentation for Fixing spawn npm ENOENT Error with pnpm dlx

Issue Overview

The error spawn npm ENOENT occurred when trying to spawn a tsserver instance using npx in a Node.js script. This error typically happens when npm is either missing or not found in the system's PATH, which is required for npx to function correctly. Although npx is supposed to work independently, it relies on npm being available in the environment. Since the project is using pnpm as the package manager, the solution is to use pnpm dlx instead of npx.

How I Resolved the Issue

1. Replace npx with pnpm dlx:

   The command that spawns the tsserver instance was originally using npx:

   const child = spawn('npx', ['tsserver'], {
    cwd: options.cwd,
    shell: true
   });

   This was changed to use pnpm dlx to make it compatible with pnpm:

   const child = spawn('pnpm', ['dlx', 'tsserver'], {
    cwd: options.cwd,
    shell: true
   });

   The pnpm dlx command is similar to npx but uses pnpm to run the specified package without requiring global installation. It ensures that pnpm is handling the execution, avoiding the spawn npm ENOENT error.

Changes Made to package.json

No changes were directly made to package.json to resolve the error. However, to ensure that pnpm dlx can be used smoothly, make sure the following:

1. Added rimraf Dependency:

   "devDependencies": {
    "rimraf": "^6.0.1",
    ...
   }

---

Conclusion

By switching from npx to pnpm dlx, the spawn npm ENOENT error was resolved. This solution is optimal for projects using pnpm as the package manager, ensuring compatibility and proper execution of the tsserver without relying on npm's presence in the environment.

PS: This solution doesn't turn off the server, which was mentioned in the issue, and it also gives the output in my Windows system.

Fix: #297

[aakash-a-dev]

This approach ensures portability and compatibility by directly resolving the tsserver binary from the project's node_modules, avoiding reliance on global tools like pnpm or npx.

Key Features of the Solution

1. No Global Dependencies:

   • Avoids relying on tools like pnpm or npx, which require global installation. Only depends on the local node_modules directory.

2. Cross-Platform Compatibility:

   • Automatically resolves to tsserver.cmd on Windows and tsserver on Linux/macOS, ensuring it works across all operating systems.

3. Version Consistency:

   • Always uses the typescript version installed in the project, ensuring consistency between development environments and deployments.

4. Shell-Free Execution:

   • Directly runs the tsserver binary without relying on shell commands, improving security and reducing potential issues.

Output

I hope this solution will be helpful for dev and end user both!
