按照官网的安装程序,可能出现的错误及常见解决办法
1.首先安装composer报错
1)下载composer.exe慢,提供下载地址:
链接:http://pan.baidu.com/s/1c2Dgsgw 密码:nwak
2)首先需要打开php.ini中的

extension=php_openssl.dll

3)需要需要加载apache下的

LoadModule ssl_module modules/mod_ssl.so

然后重启apache,再重新安装composer

2.按官方文档使用Composer安装Yii时,执行命令:

composer global require "fxp/composer-asset-plugin:~1.0.0"

会出现以下错误

C:\Users\JMJ>composer global require "fxp/composer-asset-plugin:~1.0.0"
Changed current directory to C:/Users/JMJ/AppData/Roaming/Composer
./composer.json has been created

解决办法:
更新到最新版本即可:

composer global require "fxp/composer-asset-plugin:~1.1"

当时出错时,解决插件问题,参考原文地址:http://blog.weixiaodeyu.com/class-npmrepository-does-not-exist.html

3.发现生成的目录,没有vendor
解决办法:先进入网站目录,然后composer update
更新的时间有点长
在windows中用cmd进入目录的方法,请自行搜索

4.用composer upate时会出现Hub OAuth token to go over the API rate limit,需要Github账号,登录后,在下面的链接中
获取一个token,并输入

https://github.com/settings/tokens/new

5.测试yii是否安装成功
出现如下错误

yii\web\Request::cookieValidationKey must be configured with a secret key.

解决办法:
找到config/文件夹下的web.config文件,找到cookieValidationKey,并随便赋予一个值

这时候看到
Congratulations!
