PHP警告：PHP启动：无法加载动态库'；国际和#x27；错误

我正在尝试执行命令“composer安装”命令。但是得到这个错误：

PHP Warning:  PHP Startup: Unable to load dynamic library 'intl' (tried: ./ext/intl (The specified module could not be found.), ./ext/php_intl.dll (The specified module could not be found.)) in Unknown on line 0

  Problem 1
    - The requested PHP extension ext-intl * is missing from your system. Install or enable PHP's intl extension.

这是我的php ini文件。我从“extension=intl”中删除了“；”，但它仍然给了我错误

;extension=bz2
extension=curl
extension=fileinfo
extension=gd2
;extension=gettext
;extension=gmp
extension=intl
;extension=imap
;extension=interbase
;extension=ldap
extension=mbstring
;extension=exif      ; Must be after mbstring as it depends on it
;extension=mysqli
;extension=oci8_12c  ; Use with Oracle Database 12c Instant Client
;extension=odbc
extension=openssl
;extension=pdo_firebird
;extension=pdo_mysql
;extension=pdo_oci
;extension=pdo_odbc
;extension=pdo_pgsql
;extension=pdo_sqlite
;extension=pgsql
;extension=shmop

如果您使用PHP v7.3.2，它在加载动态库intl时报告了一个错误。

简单地将您的icu*63.dll或icu*68.dll（对于PHP 8）文件从PHP目录复制到apache24/bin

它适用于Apache+PHP8.0.0 x64+intl

您安装了该扩展吗？仅仅更改配置文件并不会安装它。此外，此问题与Laravel或Composer无关-请不要使用不相关的标记，或者如果存在连接，请说明连接one@NicoHaase它存在于“ext”文件夹中，您是如何安装它的？请共享有关您的设置的更多详细信息
