I ran cargo install wasm-pack on a Windows 10 machine, and got this very long, very oblique error message:
Compiling form_urlencoded v1.1.0

Apparently this is caused by wasm-pack indirectly including openssl-sys which indirectly uses openssl-src-rs. The problem was that Perl was not installed. Probably I should have realized this, but I failed to identify I was supposed to stitch the word "perl" in stdout with "program not found" inside a panic message a few lines later; I did not know what package or program was even missing until openssl-src-rs explained it to me.
Expected behavior: Whatever crate contains this unwrap() call should first check for Err(NotFound) and if it is hit, raise a simple "Perl not installed" error message. If other software is executed out of PATH, similar checks should probably be added there too.
I filed this bug on rust-openssl and was told to refile here.
