我在 Laravel-5.1 有一个项目，我已将我的平台从 win10 更改为 Ubuntu。

To enable extensions, verify that they are enabled in those .ini files:

- /etc/php/7.0/cli/conf.d/10-opcache.ini
- /etc/php/7.0/cli/conf.d/10-pdo.ini
- /etc/php/7.0/cli/conf.d/20-calendar.ini
- /etc/php/7.0/cli/conf.d/20-ctype.ini

【问题讨论】：

嗨@kkpatel，请举一个最小的工作示例，您为解决问题所做的工作。

@Andy K 需要在 php.ini 文件中为 php7.0 和 beet change 安装 mbstring 、 yum 和 xml。

詹姆斯给了你答案。不是您为找到问题所做的工作

【参考方案1】：

您的错误消息非常明确地说明出了什么问题：

laravel/framework v5.2.9 需要 ext-mbstring * -> 您的系统中缺少请求的 PHP 扩展 mbstring。

您的服务器上是否安装了mbstring 并且已启用？

您可以将mbstring 作为 libapache2-mod-php5 软件包的一部分安装：

sudo apt-get install libapache2-mod-php5

或独立使用：

sudo apt-get install php-mbstring

安装它也将启用它，但是您也可以通过编辑您的 php.ini 文件来启用它，如果已安装它，则删除注释掉它的 ;。

如果这是在您的本地计算机上，请按照相应的步骤在您的环境中安装它。

【讨论】：

如果我错了，请纠正我：并删除 ; 将其注释掉您的意思是取消注释，因为分号表示评论，对吧？

@SaiyanPrince 我已经编辑了我的答案 - 但我的意思是说，有分号目前正在评论它

@James 感谢您提供澄清，但您的编辑没有做出任何更改。从我的角度来看，我仍然不清楚..它应该是取消评论而不是评论..

@SaiyanPrince “评论它的;”在这种情况下是正确的英文。

为什么 composer 不自动下载库 ext-mbstring？我以为它是包管理器？

【参考方案2】：

对于 php7 你可以这样做：

sudo apt-get install php-gd php-xml php7.0-mbstring

【讨论】：

对于 php 7.2 我使用了 sudo apt-get install php-gd php-xml php7.2-mbstring

终于！非常感谢您，好心的先生。

【参考方案3】：

在 php7.2 Ubuntu 18.04 LTS 和 ubuntu 19.04 中

sudo apt-get install php-gd php-xml php7.2-mbstring

像魅力一样工作

【参考方案4】：

如果您将 php 7.3 用于 laravel 5.7。这对我有用

sudo apt-get install php-gd php-xml php7.3-mbstring

【讨论】：

这是唯一对我有用的方法，我正在使用：PHP 版本 7.2.24-1 + ubuntu16.04.1 + deb.sury.org + Laravel 5.8.35

【参考方案5】：

此错误的快速解决方案

运行这个命令

composer install --ignore-platform-reqs

此命令不考虑操作系统或平台

【讨论】：

它对我有用。 Composer 正在检查平台要求，但实际上已经满足了要求。运行此命令后，一切正常

欢迎@Buraco。

【参考方案6】：

根据给定的答案安装软件包后，我仍然遇到一些错误，然后我安装以下软件包并且它工作正常：

php-xml

具体版本：

php7.0-xml

php 7.0

的命令

sudo apt-get install php7.0-xml

在某些情况下，您还需要一个包 php7.0-common 。和上面的命令一样安装。

【讨论】：

看来php版本在这里很重要...我尝试了几次使用php-xml而不是php7.*-xml。

【参考方案7】：

Ubuntu 已经有了很多好的答案。我在 Linux 上遇到了同样的问题，但上面的命令都不适合我。

对于 Linux 和 php70，我使用了以下命令，效果很好：

sudo yum install php70-mbstring -y

【参考方案8】：

这适用于我的 php 7.2

sudo apt-get install php7.2-xml

【参考方案9】：

问题：

Problem 1
    - laravel/framework v5.8.38 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - laravel/framework v5.8.38 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - laravel/framework v5.8.38 requires ext-mbstring * -> the requested PHP extension mbstring is missing from your system.
    - Installation request for laravel/framework (locked at v5.8.38, required as 5.8.*) -> satisfiable by laravel/framework[v5.8.38].

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\xampp\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

解决方案： 如果您使用 xampp，只需删除 ' ; '来自

;extension=mbstring

在 php.ini 中，保存，完成！

【参考方案10】：

在php7.4中

sudo apt-get install php-gd php-xml php7.4-mbstring
