Substrate 节点模板无法创建运行时错误=其他（“无法反序列化模块：UnknownOpcode（192）”）

Question

我正在尝试按照此过程https://docs.substrate.io/tutorials/build-a-blockchain/build-local-blockchain/#start-the-local-node启动本地节点。但它总是给我错误：

我在另一个页面看到我必须没有最新版本的 rustup，所以我目前的版本已于 2023/01/01 更新：

\n

\xe2\x9e\x9c  substrate-node-template git:(my-wip-branch) rustup toolchain list\nstable-aarch64-apple-darwin\nnightly-2021-03-14-aarch64-apple-darwin\nnightly-2022-03-14-aarch64-apple-darwin\nnightly-2022-06-30-aarch64-apple-darwin\nnightly-2023-01-01-aarch64-apple-darwin (default)\n

\n

但随后它仍然无法运行。我怀疑这是因为我必须将名称更改为 ，nightly-2023-01-01-aarch64-apple-darwin但nightly-aarch64-apple-darwin我不知道该怎么做。感谢您的帮助！

要解决这个问题，对我来说最简单的方法是在主文件夹中创建一个rust-toolchain.toml文件，其中包含以下内容：

[toolchain]
channel = "nightly-2023-01-01"
components = [ "rustfmt" ]
targets = [ "wasm32-unknown-unknown" ]
profile = "minimal"
