TS5112

Error message

tsconfig.json is present but will not be loaded if files are specified on commandline. Use '--ignoreConfig' to skip this error.

What it means

tsc error TS5058, raised in resolve_config_file when the --project argument resolves (relative to cwd) to neither an existing file nor an existing directory. The path is checked with exists() after the is_dir() branch, so this fires only for a completely missing filesystem path.

Solutions

1. Verify the path spelling and whether it should be relative to the current working directory or absolute
2. Create the missing tsconfig file or directory
3. Pass --ignoreConfig if no config file should be loaded
