Xargo不会在夜间跑步

Question

我正在尝试follow some instructions to run my Rust code on a GPU。但是，我无法编译它。

尽管我每晚安装Rust，但Xargo仍然声称没有安装Rust nightly。我尝试卸载并重新安装Xargo两次，没有任何改变。

<h4 class="result">
     {{ $batsmen->count() }} batsmen found matching your search criteria: ('{{ $batname }}', {{ $nationality_name }})
</h4>

输出：

xargo rustc --target nvptx64-nvidia-cuda -- --emit=asm

WARNING: the sysroot can't be built for the Stable channel. Switch to nightly.
   Compiling kernel v0.1.0 (file:///C:/Users/shado/Workspace/kernel)
error[E0463]: can't find crate for `core`
  |
  = note: the `nvptx64-nvidia-cuda` target may not be installed

error: aborting due to previous error

error: Could not compile `kernel`.

To learn more, run the command again with --verbose.

输出：

rustc --version

Answer 1

原来我必须运行rustup default nightly来解决这个问题。
