TypeScript compiler exited with non-zero exit code about bob

[n1ru4l]

Hey @vtereshyn, I would love to help you, can you please provide more context? In the best case a failing PR or GitHub example. bob runs tsc and overwrites a few compiler options in order to generate correct esm and cjs code.

@n1ru4l sure. this project uses one tsconfig.json and next structure:

packages
	libs
	not-libs
package.json
tsconfig.json

I see that .bob folder contains all code that I need and build was successful. Function assertTypeScriptBuildResult checks if result has exitCode not equal to 0, but here what result contains in my case:

{
  stdout: '',
  stderr: '',
  code: 0,
  failed: false,
  killed: false,
  signal: null,
  cmd: 'npx tsc --module es2022 --sourceMap false --inlineSourceMap false --outDir /.bob/esm',
  timedOut: false
}

My tsconfig.json:

{
  "compilerOptions": {
    "baseUrl": ".",
    "outDir": "dist",
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "importHelpers": true,
    "experimentalDecorators": true,
    "module": "Node16",
    "target": "ESNext",
    "lib": [
      "esnext"
    ],
    "suppressImplicitAnyIndexErrors": true,
    "moduleResolution": "NodeNext",
    "emitDecoratorMetadata": true,
    "sourceMap": false,
    "declaration": true,
    "noImplicitThis": true,
    "strict": true,
    "alwaysStrict": true,
    "noImplicitReturns": true,
    "noUnusedLocals": false,
    "resolveJsonModule": true,
    "skipLibCheck": true,
    "paths": {
    .....................
    }
  },
  "include": [
    "packages"
  ],
  "exclude": [
    "**/node_modules",
    "**/dist",
    "**/.bob"
  ]
}

Workspaces field from package.json:

  "workspaces": [
    "packages/libs/*",
    "packages/not-libs/*",
    "!packages/docs",
    "!packages/**/dist"
  ],

Please, let me know if you want me to provide more details. Thank you!

UPD: The issue was in This syntax requires an imported helper but module 'tslib' cannot be found.. But for some reasons, this error was after TypeScript compiler exited with non-zero exit code., so I wasn't able to get it.

When I went into assertTypeScriptBuildResult and put if (result.exitCode !== 0 && result.code !== 0) { instead of if (result.exitCode !== 0) { I was able to get error described above. Then, I installed tslib as a dependency, and now everything works well
