看来您在锚点项目中使用了使用BPF上无法使用的RNG的依赖性。通常，这是由于尝试在您的链程序中包括一个加密软件包的结果。
Looks like you are including a dependency in your anchor project that uses the rng which is not available on bpf. Usually this is a result of trying to include a cryptographic package in your on-chain program.
当我运行
锚点init new_program然后尝试构建它时，我也有类似的问题。我意识到我正在使用较旧版本的锚点，在AVM使用最新之后，我初始化了一个新项目，并且能够在没有此问题的情况下构建它I had a similar issue when I ran
anchor init new_programand then tried to build it. I realised I was on an older version of anchor, afteravm use latest, I initialized a new project and was able to build it without this issue我遇到了同样的问题，这对我有效，基于此。
来自cargo.toml：
I faced the same problem and this works for me based on this https://docs.rs/getrandom/0.2.6/getrandom/macro.register_custom_getrandom.html.
