• PHP开发之--安装composer


    composer是一个很好用的工具,类似于iOS开发项目中所用的cocopods,所以就想着安装下,过程也很简单:

    1、切换到如下目录(在很多博客中都是这样写的,先安装,然后mv到/usr/local/bin目录下,其实可以直接安装),这样就可以全局使用

    cd /usr/local/bin

    2、安装,输入如下命令:

    curl -sS https://getcomposer.org/installer | php

    这个时候会报错,如下:

    bogon:bin xianniuyang$ curl -sS https://getcomposer.org/installer | php
    All settings correct for using Composer
    The installation directory "/usr/local/bin" is not writable

    其实就是没有读写权限,输入如下命令,输入开机密码即可开放权限:

    sudo chmod a+x /usr/local/bin

    3、然后再次输入安装命令 curl -sS https://getcomposer.org/installer | php 即可安装,安装成功如下:

    bogon:bin xianniuyang$ curl -sS -k https://getcomposer.org/installer | php
    All settings correct for using Composer
    Downloading...
    
    Composer (version 1.9.0) successfully installed to: /usr/local/bin/composer.phar
    Use it: php composer.phar

    4、输入如下命令:

    mv composer.phar /usr/local/bin/composer

    5、在自己的PHP项目中创建composer.json文件,可以建在文件夹里面;

    6、执行如下命令:

    composer install

    7、安装成功提示如下:

    bogon:MFFC xianniuyang$ composer install
    Loading composer repositories with package information
    Updating dependencies (including require-dev)
    Package operations: 1 install, 0 updates, 0 removals
      - Installing monolog/monolog (1.0.2): Downloading (100%)         
    Writing lock file
    Generating autoload files

    项目中如下图:

     参考了几篇博客,都不怎么完整,所以按照大神博客里面的步骤自己总结了下,仅做记录!
