Hi,

error: aborting due to previous error

For more information about this error, try `rustc --explain E0433`.
error: could not compile `failure_derive`.
warning: build failed, waiting for other jobs to finish...
error: failed to compile `nsh v0.3.0`, intermediate artifacts can be found at `/tmp/cargo-installwDSerl`

Caused by:
  build failed

and rustc --explain E0433 gives :

An undeclared type or module was used.

Erroneous code example:

let map = HashMap::new();
// error: failed to resolve: use of undeclared type or module `HashMap`

Please verify you didn't misspell the type/module's name or that you didn't
forget to import it:

use std::collections::HashMap; // HashMap has been imported.
let map: HashMap<u32, u32> = HashMap::new(); // So it can be used!

Thanks

I've published v0.3.1. Could you try installing again?

It seems that the compiler error comes from failure_derive due to use of a private interface and it would be fixed by this pull request.

Published v0.3.2 since v0.3.1 is still broken.

[rapha8l]

works on both tests Thanks !

Sorry, one more :-)

Thanks for letting me know! It seems quote 1.0.2 has been yanked. However, thankfully, failure 0.1.7 which addresses the root cause is now released. I'll update Cargo.toml to fix this bug again.
