如果您使用的是WSL2,请确保遵循linuxbrew的最终linux安装说明。

test -d ~/.linuxbrew && eval $(~/.linuxbrew/bin/brew shellenv)test -d /home/linuxbrew/.linuxbrew && eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv)
test -r ~/.bash_profile && echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.bash_profile
echo "eval \$($(brew --prefix)/bin/brew shellenv)" >>~/.profile

我在Ubuntu和Arch Linux上也遇到了同样的问题。我通过在.zshrc文件中添加brew的bin文件夹路径来解决这个问题。

brew安装bin目录的路径是/home/linuxbrew/.linuxbrew/bin

将下面的行添加到~/。zshrc中 导出路径= / home / linuxbrew / .linuxbrew / bin:美元的道路

在此之后,打开一个新终端,brew命令将可用。

在我的MacBook (macOS Big Sur V 11.0.1)安装Homebrew后,我也遇到了同样的问题。

安装完成后,在控制台中会显示应该做什么:

==>下一步: -将Homebrew添加到/Users/USER/.zprofile中的PATH: echo 'eval $(/opt/homebrew/bin/brew shellenv)' >> /Users/USER/.zprofile . sh Eval $(/opt/homebrew/bin/brew shellenv) -运行“brew help”开始

按顺序执行这两个命令,会将brew命令添加到PATH:

echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/USER/.zprofile

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

可能会迟到,但肯定会有帮助。你必须首先安装brew。只要运行下面的命令就可以了:

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

也许不是很明显,但是除了上面的步骤之外,检查您的.zshprofile是否被任何多余的引号损坏。您还应该关闭所有终端实例。

基本上你的自制程序保存在/opt/homebrew/,而不是/usr/local/....路径

打开主目录下的.bash_profile并添加:

export PATH=/opt/homebrew/bin:$PATH

并重新启动终端。你会让它运行起来的。
