Try to run rustup update && cargo build --release under the vim-clap plugin directory.

[eliavo]

@liuchengxu still fails with same res code

[liuchengxu]

Interesting, never seen this before, what does rustup show say now?

[eliavo]

says the following

[eliavo]

found this about the "no active toolchain"
rustup install stable rustup default stable
after this rustup shows prompts:

even though, after rustup update && cargo build --release it fails with same res code, and after cargo clean and repeating the same command, it fails the same.

[liuchengxu]

Not sure what happened on your side, but you can build the binary using docker according to the instruction here https://github.com/liuchengxu/vim-clap/blob/5cd460ca66a734824d35e95f51750858bce1dc1c/INSTALL.md#linux.

This issue should be fixed in the latest master as the related code has been refactored away anyway.
