Windows下安装screenpipe时v8 v0.92.0构建失败问题咨询

错误核心 #

这个报错是构建v8 v0.92.0依赖时触发的，本质是无法成功获取rusty_v8的预编译静态库文件。

报错细节拆解 #

从日志能明确看到：

1. 构建脚本需要下载对应Windows平台的预编译库文件：rusty_v8_release_x86_64-pc-windows-gnu.lib.gz
2. 脚本先尝试用Python下载，失败后切换到curl，但两种方式均未成功
3. 最终因下载操作未返回成功状态，触发断言错误assertion failed: status.success()，导致构建终止

可能的解决方向 #

• 网络问题：若访问GitHub受限，手动下载该库文件，放到cargo的rusty_v8缓存目录：C:\\Users\\你的用户名\\.cargo\\.rusty_v8\\https___github_com_denoland_rusty_v8_releases_download_v0_92_0_rusty_v8_release_x86_64_pc_windows_gnu_lib_gz
• 依赖缺失：检查系统是否安装curl，或Python是否正常配置到环境变量PATH中
• 权限问题：确保screen-pipe的target目录和cargo缓存目录拥有读写权限

附用户原始操作与报错 #

已完成的安装步骤：

• 通过Chocolatey安装依赖：choco install ffmpeg pkgconfiglite rust git ✔️
• 克隆仓库：git clone https://github.com/louis030195/screen-pipe ✔️
• 切换目录：cd screen-pipe ✔️

构建失败命令：cargo build --release ❌
