我的composer.json文件在〜/ .composer：

中

{
    "require": {
        "laravel/installer": "^1.3"
    }
}

我正在使用Laravel 5.2。

Answer 1

我找到了解决这个问题的方法。

这个问题的存在是因为Laravel 5.2需要symfony / process 2.8。* | 3.0。*和Envoy需要symfony / process 2.4。*当你使用更高的symfony / process版本时，为了实现版本的不同，它会遇到一些麻烦。

<强>解决方案：

在〜/ .composer中打开composer.json文件：

$ vi ~/.composer/composer.json

它应该是这样的：

{
        "require": {
            "laravel/installer": "^1.3"
        }
    }

将其更改为：

{
    "require": {
        "laravel/envoy": "~1.0",
        "laravel/installer": "^1.3"
       }
}

现在使用：

$ composer global require "laravel/envoy=~1.0"

Answer 2

别忘了在$ PATH中提供作曲家别名

composer global require laravel/envoy

您可能需要（如果尚未）将全局作曲者目录添加到$ PATH
将此行添加到您的~/.bash_profile或~/.bashrc中。

export PATH="$HOME/.composer/vendor/bin:$PATH"

用作曲家安装Laravel Envoy的问题
