TS5083: Cannot read file 'tsconfig.json'

Common causes

• Running tsc from a directory that doesn't contain a tsconfig.json
• The tsconfig.json file was never created or was accidentally deleted
• A JSON syntax error in tsconfig.json makes it unparseable (trailing commas, missing quotes)
• A tsconfig extends path points to a file that doesn't exist

How to fix it

1. Generate a default tsconfig: npx tsc --init
2. Make sure you're running tsc from the project root where tsconfig.json lives
3. Validate the JSON in tsconfig.json — check for trailing commas and mismatched braces
4. Specify a custom config path: tsc --project path/to/tsconfig.json

Example

Running tsc without a tsconfig.json in the current directory
