我使用macbook pro并安装了flutter,但是当我输入flutter doctor
时,它没有响应(大约10分钟过去了)。
这对我issue一样,但是我没有安装Mamp软件。

听起来并不傻,您是否在线连接?当我断开与Internet的连接时,会发生这种情况。
此外,当您这样做时会发生什么?
lapply(sampleList, function(x) {
nm1 <- intersect(names(x), names(refData1))
x[nm1] <- lapply(x[nm1], function(x)
type.convert(as.character(x), as.is = TRUE))
x})
它是否仍会锁定,还是在最终继续运行Flutter Doctor之前实际检查版本?

尝试运行命令:flutter
也许您会得到一些错误,并进行修复。
我也收到错误消息:

Flutter requires PowerShell 5.0 or newer.

我修复它。

如果在Windows上尝试打开任务管理器并结束/终止所有dart.exe进程,则可能是扑朔迷离的医生正在等待另一个dart.exe进程完成该操作,无论出于何种原因

如果在Windows上并且Flutter Doctor没有响应,则表明它需要管理特权。 只需转到搜索栏,找到命令提示符并以管理员身份运行它。那应该做。
