无法构建 hidapi rust 示例

Question

filip@filip-pc:~/Desktop/hidTest$ cargo build
   Compiling pkg-config v0.3.17
   Compiling libc v0.2.71
   Compiling cc v1.0.54
   Compiling hidapi v1.2.2
error: failed to run custom build command for `hidapi v1.2.2`

Caused by:
  process didn't exit successfully: `/home/filip/Desktop/hidTest/target/debug/build/hidapi-f1cb7b18f844a4a0/build-script-build` (exit code: 101)

我只是尝试运行文档中的示例 https://docs.rs/hidapi/1.2.2/hidapi/

有人遇到过这个错误吗？

我已经试过了

cargo clean

和

cargo build

再次

Answer 1

您必须在您的系统上安装 libusb-1.0。您似乎正在使用 Homebrew，因此您还必须通过 Homebrew 专门安装它，因为 pkg-config 正在寻找它。

有可能 Homebrew 没有以这个确切的名称提供这个库，或者 hidapi crate 与 macOS 不兼容。检查 hidapi crate 了解详情，因为它是特定于 crate 的问题。
