`unknown-import`

An import path does not name a library package.

compile error, shown by synod check.

The path must name a folder that holds a library file. It fails when the folder is missing, when it holds only a main file, when the std/ package does not exist, when the module is not required or not in vendor/, or when the version differs from the selected one. The std module is imported only as std/<package>.
