我正在尝试在我的 MacBook Pro 上安装 mxnet。他们网站上的第一步是通过键入以下内容来安装 Homebrew：
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
在终端中。
这给了我下面的错误。
Conrados-MBP:~ conrados$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" curl：（1）libcurl中不支持或禁用协议“https”
我该如何解决这个问题？
【问题讨论】：
嘿@Montmons，一切都很成功，但只有一个错误。错误说
Error: Could not link:
/usr/local/share/doc/homebrew
Please delete these paths and run `brew update`.
下面是我输入时终端的输出
ruby -e "$(/usr/bin/curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
终端输出：

rm -rf /usr/local/share/doc/homebrew 然后按enter 执行删除，然后输入brew update 并再次按回车。
从这里复制以下答案：Apple StackExchange
我正在从 cmets 总结我的回答。
在您的情况下，似乎某些东西已将不支持 https 的 curl 版本安装到您的本地文件夹中。也许您尝试自己编译它（例如，标准的.configure && make && make install 程序将程序安装到/usr/local。
您可以通过将其中的curl 替换为/usr/bin/curl 来强制命令使用系统curl，因此使用：
ruby -e "$(/usr/bin/curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
成功安装 Homebrew 后，您可以使用以下命令在本地文件夹中重新安装 curl：
brew install curl
可能需要一些额外的步骤，因为您必须覆盖已经存在的文件。您可能需要使用--overwrite 选项。
