Windows users: just edit php.iniand uncomment this line:

Windows 用户：只需编辑php.ini并取消注释此行：

extension=php_fileinfo.dll

Remember to restart Apache for new php.ini to take effect.

记得重启 Apache 使新的 php.ini 生效。

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

显然这是因为php.iniweb/apache 和 CLI有单独的文件，并且 composer 使用 CLI 而 phpinfo() 使用 mainphp.ini出现问题。

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

如果您php -m在 CLI 中运行并且没有看到模块的名称，您应该找到 CLI php.ini（在我的情况下php-cli.ini并添加扩展名。例如extension=php_fileinfo.dll

Depending on your platform, there may be more php.ini, if you are using Wamp, then there are two:

根据你的平台，可能会有更多的php.ini，如果你使用的是Wamp，那么有两个：

• wamp\bin\php\php5.4.3\php.ini
• wamp\bin\apache\Apache2.4.4\bin\php.ini

• wamp\bin\php\php5.4.3\php.ini
• wamp\bin\apache\Apache2.4.4\bin\php.ini

Make sure the extension is uncomented in both and then restart apache again.

确保扩展在两者中都未注释，然后再次重新启动 apache。

I have this exactly same problem. Fixed by going to wamp/binfolder, and searching for .ini. You will find several php.inifiles.

我有这个完全相同的问题。通过转到wamp/bin文件夹并搜索.ini. 你会找到几个php.ini文件。

Edit the extension=php_fileinfo.dllline in all of them removing the ; at the begging of each. Restart WAMP, enter php -min the command-line to check if fileinfo is there now.

编辑extension=php_fileinfo.dll所有这些行中的行，删除 ; 在每个人的乞求下。重新启动 WAMP，php -m在命令行中输入以检查 fileinfo 现在是否存在。

Should work.

应该管用。

If anyone is wondering how to do this in cpanel (linux based) , just search select php version in search box and click on it and next screen you will your current php version and next you see lots checkboxes with some values , So here now you can check phpinfo and click on save to avoid your composer error.

如果有人想知道如何在 cpanel（基于 linux）中执行此操作，只需在搜索框中搜索选择 php 版本并单击它，然后下一个屏幕您将显示当前的 php 版本，然后您会看到许多带有一些值的复选框，所以现在您可以检查 phpinfo 并单击保存以避免您的作曲家错误。

Uncomment extension=php_fileinfo.dll in php ini configuration files (php.ini-development if needed) And then if you're using XAMPP, use the apache shell. It can be loaded from XAMPP Control panel run php -m to verfy that extention is loaded. Then run composer install.

在 php ini 配置文件中取消注释 extension=php_fileinfo.dll（如果需要，php.ini-development）然后如果您使用 XAMPP，请使用 apache shell。它可以从 XAMPP 控制面板加载，运行 php -m 以验证扩展是否已加载。然后运行作曲家安装。
