linux - 将 'alsa-sys'包装箱构建为依赖项时，如何安装和连接alsa.pc？

我正在尝试使用travis-ci构建rust二进制文件。我设法使Windows和osx构建正常工作，但是linux构建不断失败。

似乎“alsa-sys” crate (依赖项之一)无法在linux-vm中找到alsa.pc。

.travis.yml:

language: rust
cache: cargo
rust:
- stable

matrix:
  allow_failures:
  - rust: nightly
  fast_finish: true
os:
- osx
- windows
- linux

script:
  - cargo build --verbose --release

before_deploy:
- if [[ -f target/release/soundsense-rs ]]; then mv target/release/soundsense-rs "target/release/soundsense-rs-$TRAVIS_TAG-$TRAVIS_OS_NAME"; fi
- if [[ -f target/release/soundsense-rs.exe ]]; then mv target/release/soundsense-rs.exe "target/release/soundsense-rs-$TRAVIS_TAG-$TRAVIS_OS_NAME.exe"; fi

deploy:
- provider: releases
  skip_cleanup: true
  on:
    tags: true
    condition: "$TRAVIS_RUST_VERSION = stable"
    branch: release
  file_glob: true
  file:
  - target/release/soundsense-rs-*
  api_key:
    secure: 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

The command "cargo build --verbose --release" exited with 101.

我需要添加哪些命令来解决此问题？

最佳答案

遵循@Jmb的建议，我在before_install步骤中添加了一些软件包安装命令:

before_install:
  - if [[ "$TRAVIS_OS_NAME" == "linux" ]]; then sudo apt-get install -y libasound2-dev ; sudo apt-get install -y libwebkit2gtk-4.0 ; fi

(我还需要安装libwebkit2gtk软件包以获得另一个依赖关系)
这解决了问题。
