Warning: date_default_timezone_get(): It is not safe to rely on the system’s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected ‘UTC’ for ‘8.0/no DST’ instead in D:wapmwwwECShopuploadinstallincludeslib_installer.php on line 223

我个错误应该是没有默认时区， 从警告中可以看出是因为时区的问题。我找到uploadinstallincludeslib_installer.php文件，加上date_default_timezone_set (’Asia/Shanghai’);这名后就安装成功了。马上就可以用ecshop了。
