error instaling neos

After Installation I got the error:

#1: Warning: is_file(): Unable to find the wrapper "resource" - did you forget to enable it when you configured PHP?
in /var/www/vhosts/ line 271


Deleting all files in Data/Temporary/* and rebuilding the cache was the key to success :)

error installing neos on windows 7 / 8

During installing NEOS on windows

#1: Warning: symlink(): Cannot create symlink, error code(1) in G:\\Data\Temporary\Development\Cache\Code\Flow_Object_Classes\TYPO3_Flow_Resource_Publishing_FileSystemPublishingTarget.php line 117
More information
 TYPO3\Flow\Error\Exception thrown in file G:\\Packages\Framework\TYPO3.Flow\Classes\TYPO3\Flow\Error\ErrorHandler.php in line 77. Reference code: 20140328161044e1ea27

Windows filesystem exFAT, Fat32, UDF don't support symlinks


  • Change filessysten NTFS (otherwise symlinks are not possible at all)
  • Start the webserver as administrator (via context menu on the executable)
    • Always do so because even after installation symlinks will have to be created (e.g. by the media manager). Otherwise you may experience 500 Internal Server Error.
  • Run "flow.bat flow:cache:flush" to remove defect cache entries.
  • Continue with the setup.

Neos might run slow on Windows. If you're not developing,

  • activate "Production mode" in the .htaccess.
  • make sure that xdebug is turned off in your php.ini.

Also note the "Flow Installation Hints regarding Symlinks"

(Tested on Windows8.1 using XAMPP and Neos version 1.1.2 - September 2014)
