根据Homebrew网站,要安装它,我需要输入:

brew install wget

我得到一个错误消息:

-bash: brew: command not found

找到了这个答案。然而,问题是我在/usr/local/bin中没有看到brew。

我在.bashrc文件中添加了下面这行代码

export PATH=/usr/local/bin:$PATH

仍然得到命令未找到错误。

如何在macOS上安装Homebrew ?


当前回答

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)"

其他回答

剧本如下:

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

macOS 大苏尔

必须将此添加到终端cmd,以使Brew运行。

将Homebrew添加到/Users/*username/.zprofile中的PATH: echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/*username/.zprofile Eval $(/opt/homebrew/bin/brew shellenv)

*username =您的本地机器用户名

打开终端,输入下面的命令。 安装:

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

卸载:

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

一旦安装完成后,输入brew命令:

brew install wget
brew install node
brew install watchman
...
...

下面是一个将自制程序安装程序包装在bash函数中的版本,可以从部署脚本中运行:

install_homebrew_if_not_present() {
    echo "Checking for homebrew installation"
    which -s brew
    if [[ $? != 0 ]] ; then
        echo "Homebrew not found. Installing..."
        ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
    else
        echo "Homebrew already installed! Updating..."
        brew update
    fi
}

另一个函数将安装一个自制公式,如果它还没有安装:

brew_install () {       
    if brew ls --versions $1 > /dev/null; then
        echo "already installed: $1"
    else
        echo "Installing forumula: $1..."
        brew install $1
    fi
}

一旦你定义了这些函数,你可以在你的bash脚本中像下面这样使用它们:

install_homebrew_if_not_present
brew_install wget
brew_install openssl
...

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。
