编译

AOSP 旧的版本winscope就是一个静态的html页面（winscope.html），新版本同步完后是一个web项目（development/tools/winscope）
安装依赖

$ npm install
$ npm run build:prod
...
> winscope@0.0.0 build:protos
> node protos/build.js

node:internal/process/promises:392

分析上面的错误，发现npx 命令中的路径是错误的：/media/ken/mhd/lineage21/development/tools/winscope/protos/…/…/…/…/…/main。
找到protos/build.js，将路径改正确

// const ANDROID_BUILD_TOP = __dirname + '/../../../../../main';
const ANDROID_BUILD_TOP = __dirname + '/../../../..';

再次编译成功了。

日志抓取

启动服务，运行winscope_proxy脚本，连接手机，日志抓取遇到的问题：

$ python3 src/adb/winscope_proxy.py

看来是su命令没找到，在手机安装MagiskSU，依然出错
