Error: Command failed: Executing pkg cli from the child process of pkg cli getting failed.

[lokrajahuja]

We have a requirement to call the shell script from pkg CLI and that script is again calling the same pkg CLI.

Our CLI is calling the shell script using the child_process package of the node. In a shell script, we are again calling the Pkg CLI if some condition is met.

Following is the testing Code: test.js

const doSomething1 = () => {
  const childProcess = require('child_process');
  console.log('Do Something 1 called');
  // calling some shell script. and in script we have some condition if it is true then call doSomething2 from executables.
  childProcess.execSync('./pkgBinary 2');
}

const doSomething2 = () => {
  console.log('Do Somthing 2 called');
}

if (process.argv[2] === '1') {
  doSomething1();
} else {
  doSomething2();
}

Created binary using

pkg test.js -t 'node12-macos-x64' -o 'pkgBinary'

after the execution of command './pkgBinary 1'. I am getting the following error.

Error: Command failed: ./pkgBinary 2

As a first step towards solving your issue, please switch to using spawn/spawnSync and process.execPath because it is tested to work this way https://github.com/zeit/pkg/blob/64c40421396fdeaa3607037731962f7fca5365c3/prelude/bootstrap.js#L1451.

Have you had any luck with this issue? I think I am running into the same problem.

[stripedpajamas]

Having exactly the same issue (same stack trace); @igorklopov what are you suggesting? If I want my pkg'd app to spawn an instance of itself, how should it be done?

I've tried these and they both throw MODULE_NOT_FOUND looking for arg1:

spawn('myappname', ['arg1']) // Error: Cannot find module '/path/to/my/app/arg1'
spawn(process.execPath, ['arg1']) // Error: Cannot find module '/path/to/my/app/arg1'

I've been able to solve my specific use-case by spawning a local module within my package where I've put the functionality:

spawn(process.execPath, [require.resolve('./arg1-handler')])

But the main issue remains; I think I should be able to spawn the app itself with args. Is this supported?

I am running into the same problem, any news?

I had the same issue, and find some interesting behavior that is not documented for pkg - when you calling packed executable from outside, manually, it acts like if you call node with second argument set to internal main script ( /snapshot/project/main.js ). You can check it with console.log(process.argv) in "main.js", but you can't override it, like if it was a js function with binded first argument. But if you trying to spawn same executable recursively ( from inside that executable ), it will not be provided with second argument, which must be path to js file. so you can pass as a second argument another js file, which is responsible for your second logic branch. I create an example repo for OpenTerm I wrote, which is use same technique that i describe. - https://github.com/AndoGhevian/VT-pkg

I don't think this issue is solved. I am trying to bundle pnpm with pkg and getting this errors when there are pnpm run commands in lifecycle scripts.

Just chiming to say we're seeing the same issue in a tool we're building. Here's the relevant bug report.

Has anyone found a workaround to this?
