Question

首先，

PHP版：PHP 7.0.18＆amp; 发行版：CentOS Linux版本7.3.1611（核心版）我是一个sudo用户。

我正在设置Themosis Wordpress安装，我所有的apache配置工作都很棒。

Themosis使用Composer来管理依赖关系。我遇到的问题是当我在应用程序的根目录中运行composer install时。应该发生的是作曲家安装我需要的所有网站，包括供应商文件夹，以及一个名为cms的文件夹，其中包含Wordpress安装。我真正得到的是：

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

    - illuminate/database v5.3.23 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 v5.5.2 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

    - illuminate/support v5.4.9 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.

    - 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].

不会生成供应商文件，也不会保存Wordpress的Web文件夹。这是我到目前为止所尝试的内容：

composer require illuminate/support 5.5.* 这会失败，因为它需要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].

我尝试使用sudo yum install php-mbstring安装mbstring。这没有找到包，所以我按照this StackOverflow question中的步骤操作，并从镜像URL切换到baseurl=http://centos.intergenia.de/$releasever/updates/$basearch/。这找到了一个包，但仍然失败了。这是我们解决实际问题的地方：

错误：php70u-与php-common-5.4.16-42.el7.x86_64的常见冲突错误：php70u-json与php-common-5.4.16-42.el7.x86_64冲突

从我的Google研究中，我读到你需要为PHP7安装额外的存储库，但我不知道这意味着什么，或者这是我需要做什么，或者如何做。我不知道在我面前有谁拥有这个服务器空间，但我知道它在我开始之前已经升级到PHP 7。

试图更新yum

磁盘要求： / filesystem需要至少308MB的空间。

我不相信我的问题与肌无力或者作曲家本身有关。我找到了this possible solution，（yum install php-mbstring --enablerepo=remi），但我并不想完全破坏我的服务器，如果错误的话，我也不知道如何撤消该服务器。这个Remi存储库是我需要解决的吗？

Answer 1

您需要安装其他扩展名是与已安装的软件包相同的软件包名称空间：

remi：php-mbstring（请参阅Wizard）
webtatic：php70w-mbstring
IUS：php70u-mbstring
等

如何在升级到PHP 7后在CentOS上安装mbstring
