尝试在 CentOS 7 上安装 Homebrew 时出现错误：“错误：未知命令：shellenv”

我尝试在 CentOS 7 上安装 brew 并收到以下错误：

[jalal@goku ~]$ git clone https://github.com/Homebrew/brew ~/.linuxbrew/Homebrew

有没有在 CentOS 7 中安装 brew 的其他方法或者我如何解决这个问题？

我按照这里的说明进行操作https://docs.brew.sh/Homebrew-on-Linux

$ lsb_release -a
LSB Version:    :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:    CentOS Linux release 7.9.2009 (Core)
Release:    7.9.2009
Codename:   Core

我不知道 Homebrew 可以在 Linux 上运行。但显然它可以！

似乎这些是官方说明您的参考资料表明，在执行步骤之前，您需要安装一些先决条件。只需运行这两个命令，您就应该可以了：

sudo yum groupinstall 'Development Tools'
sudo yum install curl file git

然后运行以下命令：

git clone https://github.com/Homebrew/brew ~/.linuxbrew/Homebrew
mkdir ~/.linuxbrew/bin
ln -s ~/.linuxbrew/Homebrew/bin/brew ~/.linuxbrew/bin
eval $(~/.linuxbrew/bin/brew shellenv)

也就是说，如果您已遵循这些说明但仍然有问题，我建议您删除~/.linuxbrew/bin如下内容：

rm -rf  ~/.linuxbrew/

然后按照步骤重新安装。我建议这样做的原因是查看命令输出末尾的错误消息链：

[jalal@goku ~]$ mkdir ~/.linuxbrew/bin
mkdir: cannot create directory ‘/home/grad3/jalal/.linuxbrew/bin’: File exists
[jalal@goku ~]$ ln -s ~/.linuxbrew/Homebrew/bin/brew ~/.linuxbrew/bin
ln: failed to create symbolic link ‘/home/grad3/jalal/.linuxbrew/bin/brew’: File exists
[jalal@goku ~]$ eval $(~/.linuxbrew/bin/brew shellenv)
Error: Unknown command: shellenv

我猜是你的安装失败了mkdir: cannot create directory ‘/home/grad3/jalal/.linuxbrew/bin’: File exists，因此命令无法正常运行。只需放弃~/.linuxbrew/并重新安装，它就可以正常工作。

请记住，为您的用户安装这样的东西 - 在下面~/.linuxbrew/- 很容易删除和重新安装，所以这始终是一个安全的选择。
