Error message
noArguments
What it means
Thrown by 'yarn unplug' when --clear-all is supplied together with positional args. --clear-all already targets every unplugged package, so naming specific packages is contradictory and rejected.

Solutions
- Drop the package args: 'yarn unplug --clear-all'.
- If you want to clear only specific packages, use '--clear <pkg>...' instead of '--clear-all'.
Example fix
# before $ yarn unplug --clear-all lodash # after $ yarn unplug --clear-all
Defensive patterns
Strategy: validation
Validate before calling
if (flags.clearAll && Array.isArray(args) && args.length > 0) {
throw new Error("'--clear-all' takes no package args; remove them or use '--clear <pkgs>'.");
} Type guard
function clearAllIsClean(flags: Object, args: string[]): boolean {
return Boolean(flags.clearAll) && args.length === 0;
} Prevention
- Make wrapper scripts mutually-exclusive on --clear vs --clear-all.
- Document the two clear modes side by side to avoid confusion.
When it happens
Trigger: Running 'yarn unplug --clear-all <pkg>' where args.length > 0, so the condition (args.length && flags.clearAll) is true.
Common situations: User mixed flags (copied --clear syntax then switched to --clear-all); habit of always naming packages.
