问题描述
到目前为止，我在部署我的 laravel 项目时还没有遇到任何问题.我已经为这个项目部署了将近一年.但是出现了一些新的错误.
I haven't encountered any issue in deploying my laravel project until now. I've been deploying for like almost a year already for this project. But some new bug came up.
首先.我无法运行 composer update，因为它说这个错误.
First of all. I can't run composer update, cause it says this error.
composer update
Warning: This development build of composer is over 30 days old. It is recommended to update it by running "/usr/local/bin/composer self-update" to get the latest version.
Loading composer repositories with package information
Updating dependencies (including require-dev)
[RuntimeException]

所以我所做的是更新我的 Composer 库.
So what I did is update my Composer library.
这是我目前的版本.
Composer version 1e27ff5e22df81e3cd0cd36e5fdd4a3c5a031f4a 2014-08-11 15:46:48
我更新了作曲家.
[api@my staging-hoho-middleware]$ sudo composer self-update^C
[api@my staging-hoho-middleware]$ sudo /usr/local/bin/composer self-update
Updating to version b2173d28fc8b56236eddc8aa10dcda61471633ec.
Downloading: 100%
Use composer self-update --rollback to return to version 1e27ff5e22df81e3cd0cd36e5fdd4a3c5a031f4a
[api@my staging-hoho-middleware]$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)
但是我在运行 composer update 后遇到了一个新问题
But I encounter a new problem once I ran composer update
[api@my staging-hoho-middleware]$ composer update
Loading composer repositories with package information
Updating dependencies (including require-dev)

现在我倾向于卸载我的作曲家，并创建一个新的副本.
Now I am leaning towards uninstalling my composer, and creating a new fresh copy.
推荐答案
我通过安装缺少的依赖项来修复它.
I fixed it by installing the missing dependencies.
1008 php -v
1009 yum search php55
1010 yum -y install php55w-xml.x86_64
1011 clear
1012 su - api
1013 httpd restart
1014 service httpd restart
