Parrot OS编译Zed Code Editor时live_kit_server编译错误求助

问题描述 #

执行cargo run编译Zed时，live_kit_server v0.1.0的自定义构建命令失败，核心报错：

protoc failed: Could not make proto path relative: protocol/livekit_room.proto: No such file or directory

已尝试重新安装live_kit_server crate、切换Zed最新版本，问题仍未解决。完整报错日志：

解决方案 #

1. 拉取完整Git子模块 #

Zed依赖的LiveKit proto文件通常存储在Git子模块中，未拉取会导致文件缺失：

git submodule update --init --recursive

2. 安装并验证protoc工具 #

Parrot OS上安装官方protobuf编译器：

sudo apt update && sudo apt install protobuf-compiler

验证安装成功（要求版本3.0以上）：

protoc --version

3. 修正build.rs中的proto文件路径 #

进入live_kit_server目录查看构建脚本：

cd /home/lilo/Program_Files/zed-0.124.7/crates/live_kit_server
cat build.rs

如果脚本中引用的protocol/livekit_room.proto路径是相对当前目录的，而实际文件在仓库根目录的protocol文件夹下，需要调整路径层级，示例修改：

// 原代码
protoc_rust::Codegen::new()
    .out_dir("src")
    .input("protocol/livekit_room.proto")
    .run()
    .unwrap();

// 修改后（根据实际文件位置调整../../的层级）
protoc_rust::Codegen::new()
    .out_dir("src")
    .input("../../protocol/livekit_room.proto")
    .run()
    .unwrap();

4. 清理缓存后重新编译 #

cargo clean
cargo run
