How to Install Magento 2.3.2 with Sample Data Under Local Host?

Download magento2.3.2 at magento.com/tech-resources/download,

Remember use 127.0.0.1, instead of using localhost to intall magento. Otherwise, you will meet an error when you login the admin panel.

You may also meet a black page when you login the admin panel even if you use 127.0.0.1. How to resolve this issue then?

Very easy, go to vendor\magento\framework\View\Element\Template\File, and edit Validator.php, replace:

$realPath = $this->fileDriver->getRealPath($path);

with:

$realPath = str_replace('\\', '/',$this->fileDriver->getRealPath($path));

or do as:

Go to file Magento\Framework\View\Element\Template\File\Validator.php line 138
$realPath = $this->fileDriver->getRealPath($path);
Add after
$realPath = str_replace(‘\\’, ‘/’, $realPath);

Another thing you need to do, refresh the cache when you login the admin panel, otherwise a blank homepage will meet you!
