Was trying to use the zipfiles module and got this error (using nim 0.11.2).
could not load: libzip(|2).so(|.2|.1|.0)
Error: execution of an external program failed
A cluster administrator at my school installed nim, so I'm not entirely sure how it was done. The documentation indicates this module should link against the C libzip library (through the nim libzip module) and I'm guessing that didn't come with the standard nim download. So I'm assuming we'd need to install libzip and then link to it somehow? Also got a similar message when trying to use the re module.
Your computer just doesn't have libzip and PCRE installed. Install it.
What OS do you have?
