【问题描述】：

当我尝试安装作曲家时我收到以下错误。实际上所有模块都已安装。

据我所知，会有两个配置文件（apache2 和 cli）。

在两个配置文件中的模块都已启用。我仍然面临这个问题。

【问题讨论】：

可能看起来像一个愚蠢的问题，但您是否检查过您是否在 php.ini 中启用了扩展？

标签： php curl composer-php command-line-interface mcrypt

【解决方案1】：

尝试使用php -m 确保已在您的php 安装中启用这些模块。

如果它们不在列表中，则必须将它们添加到 php.ini 中。

【讨论】：

模块未列出。我也在 php.ini 中启用
你确定你编辑了正确的 php.ini 吗？您的服务器上可能有多个 php.ini 或多个 php 版本。
如何查看php.ini文件和路径的数量。你能给点思路吗？
您能否将php -v 的输出添加到您的问题中，并向我们展示您是如何在 php.ini 中添加扩展的？
