如何升级后安装在CentOS MBSTRING到PHP 7

Question

首先，

PHP版本：PHP 7.0.18 & 发行：CentOS的Linux的发布1611年3月7日（核心） 我是须藤用户。

我正在设置一个Themosis Wordpress安装，并且我拥有所有的apache配置工作。

Themosis使用Composer来管理依赖关系。我遇到的问题是在我的应用程序的根目录中运行composer install。应该发生的事情是，作曲家安装我需要的所有东西，包括一个供应商文件夹，以及一个名为cms的Wordpress安装文件夹。我实际得到的是这样的：

Problem 1 
    - illuminate/database v5.5.0 requires illuminate/support 5.5.* -> satisfiable by illuminate/support[v5.5.0, v5.5.2]. 
    - illuminate/database v5.5.2 requires illuminate/support 5.5.* -> satisfiable by illuminate/support[v5.5.0, v5.5.2].

    - illuminate/database v5.3.23 requires illuminate/support 5.3.* -> satisfiable by illuminate/support[v5.3.0, v5.3.16, v5.3.23, v5.3.4]. 
    - illuminate/database v5.3.4 requires illuminate/support 5.3.* -> satisfiable by illuminate/support[v5.3.0, v5.3.16, v5.3.23, v5.3.4].

    - illuminate/support v5.3.0 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system. 
    - Installation request for illuminate/database ^5.3 -> satisfiable by illuminate/database[v5.3.0, v5.3.16, v5.3.23, v5.3.4, v5.4.0, v5.4.13, v5.4.17, v5.4.19, v5.4.27, v5.4.36, v5.4.9, v5.5.0, v5.5.2]. 

供应商文件没有生成，也不是保存Wordpress的网页文件夹。以下是我试过到目前为止：

1. composer require illuminate/support 5.5.* 失败的原因是它需要MBSTRING。

结果：

Problem 1 
- illuminate/support v5.5.2 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system. 
- illuminate/support v5.5.0 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system. 
- Installation request for illuminate/support 5.5.* -> satisfiable by illuminate/support[v5.5.0, v5.5.2]. 

我试图安装与sudo yum install php-mbstring MBSTRING。这没有找到一个包，所以我遵循this StackOverflow question中的步骤并从镜像URL切换到baseurl=http://centos.intergenia.de/$releasever/updates/$basearch/。这发现了一个包，但仍然失败。这里我们得到的实际问题：

错误：与php70u常见冲突PHP-共5.4.16-42.el7.x86_64 错误：用php-共5.4.16- php70u JSON的冲突42.el7.x86_64

从我的谷歌的研究，我读了你需要安装额外的存储库PHP7，但我不知道这意味着什么，或者如果这就是我需要做的，还是怎么去做吧。我不知道谁在我之前有过这个服务器空间，但是我知道在我接手之前它已经升级到了PHP 7。

尝试更新荫

磁盘要求：需要对/文件系统 至少308MB更多的空间。

我不相信我的问题是关系到霉菌，或作曲家本身。我发现this possible solution，（yum install php-mbstring --enablerepo=remi），但不想完全破坏我的服务器，我不知道如何撤消该错误。这是Remi存储库我需要解决这个问题吗？

Answer 1

你需要安装额外的扩展是同一个包命名空间中已安装的软件包：

• 雷米：PHP-MBSTRING（见Wizard）
• webtatic：php70w-MBSTRING
• IUS： php70u-mbstring
• etc
