在 Ubuntu 上安装 Composer
在下载和安装 Composer 之前,我们需要确保我们的服务器已安装所有依赖项。
首先,运行以下命令更新包管理器缓存:
sudo apt-get update
现在,让我们安装依赖项。我们需要 curl
才能下载 Composer 和 php5-cli
来安装和运行它。Composer 使用 git
来下载项目依赖项。可以使用以下命令安装所有内容:
sudo apt-get install curl php5-cli git
现在让我们安装它:
curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
这将在/ usr / local / bin 下下载并安装 Composer,作为名为 composer 的系统范围命令。输出应如下所示:
Output
#!/usr/bin/env php
All settings correct for using Composer
Downloading...
Composer successfully installed to: /usr/local/bin/composer
Use it: php /usr/local/bin/composer
要测试你的安装,请运行:
composer
你应该得到类似这样的输出:
