我有 ext-fileinfo 但 Composer 说它丢失了 [英] I have ext-fileinfo but Composer says it is missing

问题描述

我正在尝试安装 Laravel 包 Intervention Image，当我运行 composer update 时:

I'm trying to install Laravel package Intervention Image and when I run 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 并且在 php.ini 和 phpinfo() 中启用了扩展:

I have php 5.4 and the extension is enabled in php.ini, and in phpinfo():

                    fileinfo

fileinfo support                  enabled
version                           1.0.5

并重新启动 apache ......但仍然没有运气.

and restarted apache... but still no luck.

推荐答案

显然是因为 web/apache 和 CLI 有单独的 php.ini 文件，而 composer 使用 CLI 和 phpinfo() 使用主 php.ini 出现问题.

Apparently it is because there are separate php.ini files for web/apache and CLI and as composer uses the CLI and phpinfo() uses the main php.ini the problem occurs.

如果您在 CLI 中运行 php -m 并且没有看到模块的名称，您应该找到 CLI php.ini(在我的例子中是 php-cli.ini 并添加扩展名.例如 extension=php_fileinfo.dll

If you run php -m in CLI and don't see the module's name you should find the CLI php.ini (in my case php-cli.ini and add the extension. e.g. extension=php_fileinfo.dll
