Hello: I installed dreamfactory for Linux (Centos) with this instructions: [https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat](https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat) All ok, but I get a blank page with this log error: mod\_fcgid: stderr: PHP Fatal error: require\_once(): Failed opening required ‘`[…path ommited by me…]/dreamfactory/platform/web/…/vendor/autoload.php’ (include\_path=’.:’) in […path ommited by me…]/dreamfactory/platform/web/index.php on line 54 I haven’t any directory called vendor, and haven’t any file called autoload.php. Really not exists!!. Where I can download it?, or why has not been downloaded with git?. Thanks!!. ---

What was the output when you ran the installer script? `install.sh` creates the `{installDirectory}/platform/vendor` directory, so if it doesn’t exist then I’d say something failed while running the script. ---

Well, I have an dedicated server with some domains. I created a new subdomain like [apps.domain.com](http://apps.domain.com), and I have created the subdirectories inside… /var/www/vhost/xxxx/xxxxx/apps.domain.com/dreamfactory/platform dreamfactory and platform have 777 permissions, and user.apache modified (with chown). In platform directory I have make: git clone [https://github.com/dreamfactorysoftware/dsp-core.git](https://github.com/dreamfactorysoftware/dsp-core.git) . And then I executed the installer: ./scripts/installer.sh –cv The only error is changing permissions, but I resolved it with: chown -R user.apache \* .git\* In my httpd subdomain configuration (I use Plesk panel), I have set [apps.domain.com](http://apps.domain.com) to local path: /var/www/vhost/xxxx/xxxx/dreamfactory/platform/web Now I access to [apps.domain.com](http://apps.domain.com) and I get a blank page with previous error that I have posted. …/platform/vendor is not exists!!. You think that problem is installer?. Thanks!! ---

In Apache, have you enabled the rewrite engine and set AllowOverride to All? ---

The installer script uses composer to create this directory, among others. Are you certain you’ve set everything up with the proper permissions and have run composer successfully? If you are unable to manually tune your environment as needed, I recommend using a [Bitnami package](https://bitnami.com/stack/dreamfactory). Bitnami modules may be installed [from CLI as well](https://bitnami.com/forums/forums/ez-publish/topics/install-via-command-line). ---

Hi @aman_sinha, you have installed in CentOS 7 following [the installation guide](https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat), and the installer script failed to create /platform/vendor? Please document your issue better so we can troubleshoot. ---

What is the output when you run [installer.sh](http://installer.sh)? What is logged in installer.log? Have you followed [the CentOS install guide](https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat)? Please provide additional specifics so I can replicate the behavior. ---

Did you run [installer.sh](http://installer.sh) with -cv as the options, as prescribed in the install instructions? ( [https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat](https://github.com/dreamfactorysoftware/dsp-core/wiki/Install-CentOS-RedHat) ) You should have gotten more verbose output about that error with Composer. ---

I ran into same issue. Did a few things to get here on ubuntu 14.04…One is that I immediately scrubbed apache after downloading the php packages. Next, i created a non-root sudo user ‘df’ and installed directly in that users home directory using git pull like so: `sudo git init .` ``` sudo git remote add origin https://github.com/dreamfactorysoftware/dreamfactory. git ``` `sudo git pull origin master` then installed composer ``` curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/loca l/bin --filename=composer ``` the ran `composer install --no-dev` and got error on missing vendor file Ran same with sudo and no problems… `sudo composer install --no-dev`
