在macOS终端中无法执行命令，为什么？

Question

我有一个问题..

1. 我安装了ZSH、Composer和Laravel Installer；
2. 在~/.zshrc中，我添加了“~/.composer/vendor/bin”到$PATH中。
3. 当我执行“echo $PATH”时，我得到的字符串是：

~/.composer/vendor/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:

但是当我尝试执行

laravel new blog 

我遇到了一个错误消息

zsh：找不到命令：laravel。

如果我创建别名-它可以正常工作。

没有别名，Composer也无法正常工作。

那么我的问题在哪里？我认为我更改了$ PATH以不创建别名，但它不起作用。

你能否编辑你的问题并附上你的zsh配置？ - Fabio Antunes

在你的echo $PATH中不应该显示~。请在你的zshrc文件中将~替换为$HOME，或确保其中的~/没有被引号包含。 - Mat

Answer 1

我在$PATH中添加了"~/.composer/vendor/bin"，它在~/.zshrc文件中。

"~/"在~/.zshrc中不会被展开，你需要使用完整路径（例如/Users/groovyme/.composer/vendor/bin）或者一个环境变量（如$HOME），它可以扩展到该完整路径。

希望对你有所帮助。
