typescript Buffer 类型 toString 需要 0 个参数

Question

我有这个简单的打字稿代码：

const y = Buffer.from("fds")
y.toString("hex")

但是我在“十六进制”上收到 tsc 类型错误，提示

Expected 0 arguments, but got 1.

toString 方法接受一个参数https://nodejs.org/api/buffer.html#buftostringencoding-start-end

所以看来我的类型对于这个标准库来说不知何故不是最新的？

╰─❯ node -v
v20.12.2

╰─❯ yarn tsc -v
Version 5.3.2

我正在跑步

yarn run tsc --noEmit --p ./src --incremental"

我的 tsconfig

  "include": ["./src/**/*", "./mmmEval"],

您需要向项目添加缺少的依赖项：

@types/node

节点的类型定义。

yarn add @types/node

这应该可以解决你的问题
