I don’t find any syntax error in package.json I am trying from a long time but the same error exist. You will notice i have given absolute path for the entry as

entry: ‘main.ts’,

when i give relative path (entry: ‘./main’) it gives error ERROR in Entry module not found: Error: Cannot resolve ‘file’ or ‘directory’ ./main in D:\ProjectPath

Then it resolves the path for main.ts and finally gives the error as mentioned above. ERROR in Entry module not found: SyntaxError: D:\ProjectPath\package.json (directory description file): SyntaxError: Unexpected token

This is very strange behavior. Please let me know if anybody found same issue and how did u resolve?

Thank you.

@blackcloud2333 try to:

1. copy content of package.json (skip the first line since from the error message I would say there is some special character hidden in the beginning of the file)
2. remove package.json
3. create new package.json file and paste content (retype first line)
