正常安装，试了几次都有这个问题，已经略过了，不知道对后续有没有影响
在执行composer update这个指令时候回报这个错误，我在官网查了一下，composer升级版本命令是composer self update，那么这个composer update应该是升级fecshop吧？
oot@wt:/home/wwwroot/fecshop# composer update
The "extra.asset-installer-paths" option is deprecated, use the "config.fxp-asset.installer-paths" option

To enable extensions, verify that they are enabled in your .ini files:
- /usr/local/php/etc/php.ini
- /usr/local/php/conf.d/002-zendguardloader.ini
You can also run php --ini inside terminal to see which files are used by PHP in CLI mode.
中间我查了一下 /usr/local/php/conf.d/002-zendguardloader.ini
[Zend ZendGuard Loader]
zend_extension=/usr/local/zend/ZendGuardLoader.so
zend_loader.enable=1
zend_loader.disable_licensing=0
zend_loader.obfuscation_level_support=3
zend_loader.license_path=

这个配置，没有错，如果再去php.ini中配置这个参数，就会抱一个double的错误，证明这个参数配置生效了，但是错误
我网上搜了一下，是没安装PHP5-CURL
然后更新了一下ubuntu的php curl，已经没有php5-curl了，只有php-curl和php7.0-curl了，不知道有没有影响
