Error while installing Magento

Question

I have downloaded the Magento community edition and the sample data. I am using XAMPP and while when I try to install Magento, all the five steps are fine as you can see below

When I click on the install button, the installation process stops with following error message

Module 'Magento_Widget':

Please somebody help me resolve this issue

Answer 1

问题是，数据库不干净。所以安装时确保数据库为空，现在安装成功。

Answer 2

1. First of all make sure that you have entered right database name at database details step.

2. Check your database it must be clean. If you have imported the database from your Magento theme then clean it or create empty database. (Note : Database should be empty during Magento installation)
