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。

检查是否安装了Xcode:
$ gcc --version
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
$ brew doctor
$ brew update

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
检查是否安装了Xcode:
$ gcc --version
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
$ brew doctor
$ brew update

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
...
不知道为什么没有人提到这一点:当你从官方网站运行安装命令时,在最后几行你会看到如下内容,你需要遵循==>下一步:
==> Installation successful!
==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
https://docs.brew.sh/Analytics
No analytics data has been sent yet (or will be during this `install` run).
==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
https://github.com/Homebrew/brew#donations
==> Next steps:
- Add Homebrew to your PATH in /Users/{YOUR USER NAME}/.bash_profile:
echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/{YOUR USER NAME}/.bash_profile
eval $(/opt/homebrew/bin/brew shellenv)
这是bash shell的。对于每个不同的shell,您将看到不同的步骤,但是这些步骤的源是相同的。
我可能迟到了,但是有一个很酷的网站,你可以在那里搜索软件包,它会列出安装这些东西的必要命令。 BrewInstall是网站。
但是你可以用下面的命令安装wget:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
brew install wget
希望这对你有所帮助。
