问题
My site is on live online server, after installing few modules (user definded forms) via SSH and Composer i get 500 internal server error.
I try to run /dev/build/?flush but nothing is happening. Again the some error!
I check in chrome to inspect in network tab and there is also 500. So dev env in not enabled.
I try to enable it:
_config.php
Config::inst()->update("Director", "environment_type", "dev");
config/config.yml :
Director:
environment_type: 'dev'
And nothing is happening. It wont to change on dev env to allowe me to run dev/build?flush. I realy dont know what i do wrong.
I also try this way inside _config.php
ini_set('display_errors', 1);
error_reporting(E_ALL);
Director::set_environment_type('dev');
SS_Log::add_writer(new SS_LogFileWriter('./logs/'), SS_Log::WARN, '<=');

This will always put SilverStripe in dev environment.
_config.php
require_once("conf/ConfigureFromEnv.php"); //add this
global $project;
$project = 'mysite';
global $databaseConfig;
//Database configuration
_ss_environment.php
define('SS_ENVIRONMENT_TYPE', 'dev');
error_reporting(E_ALL);
ini_set('display_errors', '1');
define('SS_DATABASE_SERVER', 'localhost');
define('SS_DATABASE_USERNAME', '');// you can leave this empty if you defined this in your _config.php
define('SS_DATABASE_PASSWORD', '');// you can leave this empty if you defined this in your _config.php

You can change to dev environment quickly for the current session if you add ?isDev=1 to your URL, see docs.
If it still doesn't work you need to set up error logging and/or get the webserver error log to see what's going wrong.
As you installed a module in command line ... did you run
./framework/sake dev/build ?flush=1
from your webroot in ssh (see cli docs) to rebuild the database? If not, please try it and be sure it ends with "done", otherwise look out for error messages.
