windows 手动安装 composer

作者:互联网

  1. 首先 php 已经配置到环境变量
  2. 打开命令行窗口,进入你想安装 composer 的目录
  3. 执行命令:
php -r "readfile('https://getcomposer.org/installer');" | php

此过程可能会报错:

Warning: readfile(): SSL operation failed with code 1. OpenSSL Error messages:

error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify faile

d in Command line code on line 1

Warning: readfile(): Failed to enable crypto in Command line code on line 1

Warning: readfile(https://getcomposer.org/installer): failed to open stream: ope

ration failed in Command line code on line 1

解决办法:
确保 php.ini 已经 开启 openssl 并配置了 CA 证书

openssl.cafile=E:\PHPTools\php\cert\cacert.pem

  1. 最后执行命令:
echo @php "%~dp0composer.phar" %*>composer.bat

然后将此 composer 目录配置到环境变量,重新打开 cmd 命令窗口,执行 composer -v 如果看到版本信息说明安装成功
此过程需要能访问 getcomposer.com ,该网址被墙了,如果无法访问,可以自行百度下载 composer.phar 文件,然后执行上面的 echo 语句生成可执行文件,就可以了

官方下载地址:http://getcomposer.org/composer.phar
