编写器错误：您的系统&quot；中缺少PHP扩展名fileinfo(&quot；PHP扩展名文件信息

我正在尝试安装Laravel包干预映像，运行时composer update：

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - intervention/image 2.0.5 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - intervention/image 2.0.4 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - intervention/image 2.0.3 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - intervention/image 2.0.2 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - intervention/image 2.0.1 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - intervention/image 2.0.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
    - Installation request for intervention/image 2.* -> satisfiable by intervention/image[2.0.0, 2.0.1, 2.0.2, 2.0.3, 2.0.4, 2.0.5].

我有php 5.4，php.ini和phpinfo()中启用了扩展：

                    fileinfo

fileinfo support                  enabled
version                           1.0.5

并重新启动Apache.但还是没有运气。

解决方案

显然是因为Web/apache和cli有单独的php.ini文件，而Composer使用的是命令行界面，而phpinfo()使用的是主php.ini。

如果您在CLI中运行php -m，但没有看到模块名称，您应该找到CLIphp.ini(在我的示例中是php-cli.ini并添加扩展名。例如extension=php_fileinfo.dll
