作曲家全局需要“laravel/envoy=~1.0”

我在 ~/.composer 中的 composer.json 文件：

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

我正在使用 Laravel 5.2。

我找到了解决这个问题的方法。

存在这个问题是因为 Laravel 5.2 需要 symfony/process 2.8。* | 3.0.* 和 Envoy 需要 symfony/process 2.4.* 并且当您使用更高版本的 symfony/process 时，为了实现版本的差异会遇到一些麻烦。

解决方案：

在 ~/.composer 中打开 composer.json 文件： 

$ vi ~/.composer/composer.json

它应该如下所示：

{
        "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"

不要忘记让您的作曲家别名可从您的 $PATH

composer global require laravel/envoy

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

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