Like @Hugehornet pointed out - you should enable this extension in php.ini by uncommenting this line: extension=ext/php_intl.dll
就像@Hugehornet 指出的那样 - 你应该通过取消注释这一行来在 php.ini 中启用这个扩展：extension=ext/php_intl.dll
If you use wamp's interface for this task you are actually updating the php.ini file located in apache's directory.
如果您为此任务使用 wamp 的界面，您实际上是在更新位于 apache 目录中的 php.ini 文件。
Example: C:\wamp\bin\apache\Apache2.4.4\bin\php.ini
示例：C:\wamp\bin\apache\Apache2.4.4\bin\php.ini
Composer is using the one located in the php's installation directory.
Composer 正在使用位于 php 安装目录中的那个。
Example: C:\wamp\bin\php\php5.4.12\php.ini
示例：C:\wamp\bin\php\php5.4.12\php.ini
You should manually edit the latter and restart the wamp server.
您应该手动编辑后者并重新启动 wamp 服务器。

You need to enable the intl extension in php just as the error says.
In your php.ini file, uncomment the line extension=ext/php_intl.dllor something like this.
正如错误所说，您需要在 php 中启用 intl 扩展。在您的 php.ini 文件中，取消注释该行extension=ext/php_intl.dll或类似内容。
Edit : note that if you are using wamp or something like this, you should be aware of the fact that the php.ini file in the wamp config is not necessarily the one used by composer.
编辑：请注意，如果您使用 wamp 或类似的东西，您应该意识到 wamp 配置中的 php.ini 文件不一定是 Composer 使用的文件。

First of all be sure that your server is isung x86 build (intl not working with x64), then:
首先确保您的服务器是 isung x86 构建（intl 不适用于 x64），然后：
- activate intl extension in
php.inidirectly - copy all
icu*.dllform php directory to apache directory - make sure your console using the same php folder you just configured source.
php.ini直接激活国际扩展- 将所有
icu*.dll表单php目录复制到apache目录 - 确保您的控制台使用与您刚刚配置source相同的 php 文件夹 。
In my windows system I have two php.inifiles at the flowing paths:
在我的 Windows 系统中，我php.ini在流动路径中有两个文件：
C:\wamp\bin\php\phpx.y.z
C:\wamp\bin\apache\Apachex.y.z\bin
I don't know which one is in your path. Just make sure to add the extension in both of them to eliminate any doubt.
我不知道你的路径是哪一个。只需确保在它们两个中添加扩展名即可消除任何疑问。

If intl has already been enabled and it doesn't works, add your PHP directory in the Path environment variable, then restart your server. (for example C:\Program Files\wamp\bin\php\phpX.XXX.XXX for wamp)
如果已经启用了 intl 并且它不起作用，请在 Path 环境变量中添加您的 PHP 目录，然后重新启动您的服务器。（例如 C:\Program Files\wamp\bin\php\phpX.XXX.XXX 表示 wamp）
It has worked for me!
它对我有用！

On Ubuntu, Debian, and related Linux distributions
在 Ubuntu、Debian 和相关的 Linux 发行版上
sudo apt-get install php-intl
to install the extension for the default PHP version.
For other versions a variation like apt-get install php7.3-intlwill choose the correct extension if the version provided is correct.
安装默认 PHP 版本的扩展。对于其他版本，apt-get install php7.3-intl如果提供的版本正确，则变体 like将选择正确的扩展名。
