我尝试在 Ubuntu 16 中使用 PHP 5 安装 xdebug，但失败了。我使用的命令是：
sudo pecl install xdebug
我在论坛上搜索了很多，但找不到导致此问题的原因。有人能帮我解决吗？
以下是控制台输出的错误：

答案1
Ubuntu Xenial 中唯一支持的 PHP 版本是 7.0，并且 php5 软件包将在最终发布之前被删除。
但是，要修复这个错误，您需要修复 php5-dev 包中包含的 ltmain.sh 符号链接：
ln -sf /usr/share/libtool/build-aux/ltmain.sh /usr/lib/php5/build/ltmain.sh
或者您可以使用ppa:ondrej/php5-5.6已经有该修复程序和最新上游版本的。
答案2
您也可以先运行“apt install php-dev”，然后再运行“pecl install xdebug”。
这将安装适用于 php7 的开发工具。上面的答案更像是一种变通方法，让一组 php5 开发工具与 php7 配合使用。
