在我尝试了所描述的一切之后，我查看了/usr/local/etc/ brew文件夹权限。不知何故，权限被更改了，我无法打开文件夹。我改变了文件夹权限(用chmod)与其他文件夹的权限相同，并开始工作。

对我有用的是设置BREW_FILE_DIRECTORY，如下所示

echo "export BREW_FILE_DIRECTORY=/opt" >> ~/.zshrc .

因为brew.sh文件在/opt/homebrew/bin下 在脚本中，所有内容似乎都是从BREW_FILE_DIRECTORY变量计算出来的。这在MacBook Pro (M1)上是可行的

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)"

您可以使用以下命令安装brew。

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

然而，当使用这个你会得到警告，它购买自制安装程序现在已弃用。建议改用Bash。

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

如果你使用的是m1芯片mac，那么在安装homebrew后运行以下命令并再次打开终端:

echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc
