使用-mode simple采集模式可以采集成功，但是没有ftrace信息。

检查下是不是没有安装python3环境？如果已经有了，可以再确认下直接使用官方的方式采集Perfetto的trace会不会遇到问题，https://perfetto.dev/docs/quickstart/android-tracing

curl -O https://raw.githubusercontent.com/google/perfetto/master/tools/record_android_trace

@bianmajiang 脚本里面写死的python3，你看看创建一个python3的别名呢，后面我们都兼容下。

[bianmajiang]

可以了。

请问除了python的问题还有什么会导致这个问题吗，我本地已经有python3且可以正常运行，但是依然存在Error: systrace file not found: rheatrace.workspace\systemTrace.trace问题
