Magento2: Windows separator fix on Magento 2.3

[vincent-bosche]

Preconditions (*)

1. Magento 2.3.0 (fresh installation from composer)
2. Windows only

Steps to reproduce (*)

1. Open any URL in frontend or backend

Expected result (*)

1. The correct output

Actual result (*)

Exception #0 (Magento\Framework\Exception\ValidatorException): Invalid template file: '[..]/vendor/magento/module-theme/view/frontend/templates/page/js/require_js.phtml' in module: '' block's name: 'require.js'

#10 [..]\index.php(39): Magento\Framework\App\Bootstrap->run(Object(Magento\Framework\App\Http\Interceptor))
#11 {main}

1. Magento\Framework\View\Element\Template\File\Validator function isPathInDirectories: Windows uses "\" as separator, the array "directories" contains entries with "/" as separator, so the check will always fail.
   $realPath = str_replace('\\', '/', $this->fileDriver->getRealPath($path)); could be a solution.

I've run Magento on Windows servers for years without any issues. The fix for me was replacing
$realPath = $this->fileDriver->getRealPath($path);
with
$realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));

[PathToLife]

Can reproduce, fresh install of magento 2.3 on development wamp server is totally borked.

PLEASE INSTALL NEW RELEASES ON WINDOWS AT LEAST ONCE =P

@vincent-bosche Did you solve in windows platform?

[saktib]

For Windows, this is the workaround for now, modify this below file {Magento_Dir}\vendor\magento\framework\View\Element\Template\File\Validator.php

Comment the existing $realpath around line 138 and add the new $realPath

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

[Jeeva-Rathinam]

@saktib Still getting same error after update $realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));
Anything else shall i need to focus?

[saktib]

@Jeeva-Rathinam
From your comment I can see you are missing one backslash, it should be like below.
$realPath = str_replace('\\', '/', $this->fileDriver->getRealPath($path));

[amustci065]

@saktib Still getting same error after update $realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));
Anything else shall i need to focus?
Try this $realPath = str_replace('\', '/', $this->fileDriver->getRealPath($path));

I think you're going down the wrong path installing with windows. Waste of time with M2.3. The routing and build system is bound to have other errors that will keep popping up.

[Jonathonbyrd]

I'm on Ubuntu 18 and I'm still getting this issue. The proposed fix did not fix the problem for me. Telling the customer to use a different operating system is not the kind of support that Magento would allow Extension developers to get away with.

A solution that did work for me was to specify a Theme for the website. Upon installation this seems to have been lost and the db was giving a blank string for the theme name.
