Your requirements could not be resolved to an installable set of packages.
Problem 1
- This package requires php >=7.0.0 but your PHP version (5.6.33) does not satisfy that requirement.
How can I fix this? NOTE : I'm not allowed to uninstall previous version of php
我怎样才能解决这个问题？注意：我不允许卸载以前版本的 php
Here is the composer.json

composer update --ignore-platform-reqs
but I still I get another error, which is again related to the above problem.
但我仍然收到另一个错误，这又与上述问题有关。

As stated in the question you already have both the versions of PHP on your system, As Laravel uses the cli version you need to enable 7.X and disable 5.X.
正如问题中所述，您的系统上已经拥有两个版本的 PHP，因为 Laravel 使用您需要启用 7.X 和禁用 5.X 的 cli 版本。
You can achieve that by below commands
您可以通过以下命令实现
$ sudo a2dismod php5.6 // disable the loaded version
$ sudo a2enmod php7.0 // enable the desired version
$ sudo service apache2 restart // restart apache to get it in action
For More information You can install different version of PHP using the below commands
有关更多信息，您可以使用以下命令安装不同版本的 PHP
For Apache
对于阿帕奇
$ sudo apt install php5.6 [PHP 5.6]
$ sudo apt install php7.0 [PHP 7.0]
$ sudo apt install php7.1 [PHP 7.1]
For Ngix
对于 Ngix
$ sudo apt install php5.6-fpm [PHP 5.6]
$ sudo apt install php7.0-fpm [PHP 7.0]
$ sudo apt install php7.1-fpm [PHP 7.1]

Check where your composer executable is located (using which) and check the first line (shebang). I guess this still points to old php version.
检查您的 composer 可执行文件所在的位置（使用 which）并检查第一行（shebang）。我想这仍然指向旧的 php 版本。

If you want to run composer with a different PHP version, try calling it using php $(which composer) update. You can exchange the path to the PHP cli now freely
如果您想使用不同的 PHP 版本运行 composer，请尝试使用php $(which composer) update. 您现在可以自由交换 PHP cli 的路径
