[xwiki-users] Problem installing xwiki 7.1.1

Hi, I install wiki with debian package. My system is a Debian 7 or a Debian 8. On the both servers, i have the same errors. With packages, the install is OK. With the browser, i open the page localhost:8080 The install starts and it is very very long (but i have a fiber optic !!!) After install finished, i view the home page of the wiki. And here, i have many errors in Javascript : ReferenceError: require is not defined Why ? Impossible to solve these errors !! And the wiki don’t work !! Impossible to edit a page !!! I have purge all the debian packages and i started a new install . For the same result !!!! How do you do to solve this error ? thanks for your help.. Julien
