Question

我正在使用Macbook。在运行Flutter Channel Master和Flutter升级后，出现以下错误。

请问对此有什么解决方案吗？

解决方法是首先尝试在您的系统中找到sysctl 的安装。在某些 MacO 中，它位于 /usr/sbin。那么，如何发现呢？在终端中执行以下命令：whereis sysctl 或 which sysctl。结果将类似于：/usr/sbin/sysctl。之后，将其添加到 PATH。

# Adding /usr/sbin/ to path
PATH=/usr/sbin/:${PATH}
export PATH

将其复制并粘贴到 ~/.bash_profile 或 ~/.zshrc 文件中。重新启动您的终端（关闭它并再次打开）并运行 flutter doctor。大功告成！
