我试图设置服务器环境的本地版本（Apache2，CiviCRM，Drupal7，PHP7.3），以便在本地测试某些代码更改。
但是在/var/log/apache2/error.log文件中，我收到有关PHP扩展的以下错误：

浏览器中的phpinfo()在“已解析的其他.ini文件”部分中显示了所有上述扩展名，但gd2除外。 （尽管它确实显示了gd。）
我已经检查了php.ini文件并在“扩展”部分中激活了所需的扩展，并将“路径和目录”部分中的extension_dir更改为正确的路径（/ usr / lib / php / 20180731）。
我还尝试安装错误日志先前版本中标记为“找不到文件”的扩展名（pdo_firebird）：实际上，文件pdo_firebird.so在/ usr / lib中不存在。 / php / 20180731目录。当我安装它并且文件pdo_firebird.so确实存在时，它开始抛出当前错误（pdo_firebird.so: undefined symbol: php_pdo_unregister_driver）。
所以我感觉到正在发生更深层的错误，安装丢失的扩展名并不能解决问题，因为新的错误将会出现。
有人有什么提示吗？ ：）
编辑：我在/ usr / lib / php / 20180731目录上做了chmod -R 777，但是错误仍然存在。
