我在mac BigSur M1处理器上安装Homebrew时遇到了同样的brew命令找不到的问题。

I -安装XCode，如果它还没有安装。

II -选择终端。应用程序在Finder。

III -人民币点击终端，选择“获取信息”

IV -选中“使用Rosetta打开”复选框。

关闭所有打开的终端窗口。

打开一个新的终端窗口，安装Hobebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

测试自制软件的安装。

IIX -取消勾选使用Rosetta打开复选框。

Brew现在已经用Bash重写了!

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

在一个开箱即用的MacOS High Sierra 10.13.6

$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

给出以下错误:

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). If the default bundle file isn't adequate, you can specify an alternate file using the --cacert option. If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL). If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option. HTTPS-proxy has similar options --proxy-cacert and --proxy-insecure.

解决方案:只要在你的卷曲选项中添加一个k

$ ruby -e "$(curl -fsSLk https://raw.githubusercontent.com/Homebrew/install/master/install)"

解决“-bash: brew:命令未找到”问题

将Homebrew添加到/Users//.bash_profile中的PATH:

echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users//.bash_profile . sh

eval $(/opt/homebrew/bin/brew shellenv)

剧本如下:

- usr/bin/ruby -e“curl -fsSL” https://raw.githubusercontent.com/Homebrew/install/master/install)”

如果运行后仍然报错，

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

然后尝试从https://developer.apple.com/download/more/下载并安装命令行工具，适用于特定的Mac os和Xcode版本。

然后试着跑，

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

然后

brew install node
