Composer-Fehler, dass Informationen zur PHP-Erweiterungsdatei im System fehlen

Question

Ich versuche, das Laravel-Paket-Interventions-Image zu installieren und wenn ich composer update ausführe:

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].

Ich habe PHP 5.4 und Erweiterungen aktiviert in php.ini 和 phpinfo():

fileinfo

fileinfo support                  enabled
version                           1.0.5

und Apache neu gestartet ... aber immer noch kein Glück.

Answer 1

Windows 用户：只需编辑 php.ini 并取消注释此行：

extension=php_fileinfo.dll

记得重新启动 Apache 以使新的 php.ini 生效。

Answer 2

显然这是因为 web/apache 和 CLI 有单独的 php.ini 文件，并且作曲家使用 CLI 而 phpinfo() 使用主 php.ini出现问题。

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 php- cli.ini 并添加扩展名。例如 extension=php_fileinfo.dll
