错误cargo build sbf无法获取包元数据：“cargometadata”退出并出现错误：错误：无法加载工作区成员的清单

Question

我尝试建立一个锚定项目

anchor init AnchorProject

cd AnchorProject

anchor build

然后出现这个错误！

admin@Desktop MINGW64 /d/folder_1/MY_Project/AnchorProject (main)
$ anchor build

Warning: cargo-build-bpf is deprecated. Please, use cargo-build-sbf

cargo-build-bpf child: 
C:\Users\admin\.local\share\solana\install\active_release\bin\cargo-build-sbf.exe --arch bpf

[2022-09-23T17:22:59.130309300Z ERROR cargo_build_sbf] Failed to obtain package metadata:

    Caused by:
      The filename, directory name, or volume label syntax is incorrect. (os error 123)

而且我不明白上面消息中的问号（？）是什么意思！

注意

我已经解决了元数据的问题，但是当我返回构建项目时，出现了另一条消息

$anchor build

error: no such subcommand: build-bpf 

Did you mean build-sbf?

当我尝试编写cargo-build-bfs时，还会出现另一条消息

$cargo-build-bfs

Answer 1

Solana 程序不能包含

rand

，因为这会导致不确定的结果。程序无法执行 I/O（文件、屏幕、url、网站、rand 等）

参见 Rust 程序构建限制：

Answer 2

我是 Solana 和主播的新手。现在我面临着您上面提到的问题 - 元数据问题。请告诉我你是怎么解决的？
