当我localhost:8899在 chrome 中运行时，响应“不允许使用使用的 HTTP 方法。需要 POST 或 OPTIONS”

我需要说我对 docker 完全是新手，但教程需要它。

不幸的是，您似乎正在使用新旧混合。您看到的错误：

Error: failed to get recent blockhash: Invalid params: unknown variant `finalized`, expected one of `max`, `recent`, `root`, `single`, `singleGossip`.

是因为您使用的是较新版本的 @solana/web3.js 和非常旧的网络版本。最简单的解决方案是降级到 @solana/web3.js 版本 0.78.2 以继续遵循教程。

另外，还有许多用于本地开发的新工具。如果您使用的是新版本的网络和 SDK，则有一个名为solana-test-validator( https://docs.solana.com/developing/test-validator ) 的二进制文件，它比针对 Docker 进行开发要容易得多。
