我一直尝试遵循的说明看起来很简单，如下所示：将 PHP 从 5 更新至 7但我总是遇到一些错误。在链接的示例中，所有命令似乎都可以正常工作，但当我执行实际的安装命令时
yum install php php-common php-cli php-mysql
我得到这个输出：

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
PHP 版本停留在 5.6.38。不知道如何解决这个问题，希望得到帮助！
答案1
您应该删除php56u-pecl-jsonc，因为存储库中没有等效内容。
这佩克尔是 PHP C 扩展的存储库，有时会导致冲突。PHP 有一个非常好的 json 库，这是一个替代方案，如果您不需要，可以删除：
yum remove php56u-pecl-jsonc
或者使用此命令删除所有 PHP 包 - 但要小心操作：
rpm -qa '*php*' | xargs yum remove -y
然后，为了安全起见，清理缓存并安装新的：
yum clean all
yum install php php-common php-cli php-mysql
这应该可以解决。
