下面由composer教程欄目給大家介紹composer init 命令，希望對(duì)需要的朋友有所幫助！

前言

今天安裝了node，準(zhǔn)備用npm 下載項(xiàng)目所需要的依賴包

由于本人英語(yǔ)不太好，在執(zhí)行 composer init 命令后，憑借著經(jīng)驗(yàn)知道需要輸入什么信息，但還是不太明白，也了解軟件人性化的地方，不輸入肯定有默認(rèn)值，果然一通回車后，居然 OK了，當(dāng)時(shí)感覺(jué)真的應(yīng)了網(wǎng)上說(shuō)的那句話 “一通操作猛如虎，一看結(jié)果250”。

為了搞明白composer init命令后需要輸入那些信息，以及輸入信息的規(guī)范，我在下午詳細(xì)介紹一下：

composer init 命令詳解

使用系統(tǒng)再帶的curl安裝composer

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

驗(yàn)證composer是否安裝成功

dduan@dduan:~/test_composer$ php composer.phar    ______   / ____/___  ____ ___  ____  ____  ________  _____  / /   / __ / __ __ / __ / __ / ___/ _ / ___/ / /___/ /_/ / / / / / / /_/ / /_/ (__  )  __/ / ____/____/_/ /_/ /_/ .___/____/____/___/_/                     /_/ Composer version 1.8.6 2019-06-11 15:03:05

composer init 命令后續(xù)步驟詳解

root@dduan:/home/dduan/test_composer# php composer.phar init Do not run Composer as root/super user!

注意

composer init 和 npm init 命令后續(xù)操作類似 。
