CLI - ENOENT: no such file or directory, open 'package.json'

[yoursunny]

Since v2.2.0, the CLI command does not work if it's invoked in a directory without a package.json file.

Snippet to Reproduce

package.json

{
  "private": true,
  "packageManager": "pnpm@9.1.3+sha512.7c2ea089e1a6af306409c4fc8c4f0897bdac32b772016196c469d9428f1fe2d5a21daf8ad6512762654ac645b5d9136bb210ec9a00afa8dbc4677843ba362ecd",
  "dependencies": {
    "ts-json-schema-generator": "2.2.0"
  }
}

def/waypoint.ts

export interface Waypoint {
  lat: number;
  lng: number;
}

Node.js v20.13.1

Cause Analysis

The offending line is:

ts-json-schema-generator/ts-json-schema-generator.ts

Line 11 in 0828229

const pkg = JSON.parse(fs.readFileSync("package.json", "utf8"));

This was introduced in #1964.

It reads the content of package.json into pkg variable, which is then used to display the version number of ts-json-schema-generator package:

ts-json-schema-generator/ts-json-schema-generator.ts

Line 54 in 0828229

.version(pkg.version)

For this purpose, the command should be reading path.join(import.meta.dirname, "package.json") rather than package.json in current working directory, because:

• If current working directory does not have package.json file, it leads to ENOENT error.
• If current working directory has package.json file, the command would display the version number of the downstream package, instead of the version number of ts-json-schema-generator package.

#1975 might solved this issue already, could you try with v2.3.0-next.2?

[yoursunny]

I already tried v2.3.0-next.2 and it also suffers from this issue.

v2.3.0-next.3 🚀
