Some Drush master-branch commands report DB problem in Drupal 8 I use Drupal 8.0.0 in a Windows 10 home, WAMP environment.

When I run for example drush up, I get:


  The drush command 'up' could not be executed. Drush was not able to
  start (bootstrap) the Drupal database



Every action is done when I am in the sites folder (C:\wamp\www\sname>).
This is a brand new environment - I've only one DB named equally as it's user.


Update:

After I tried to follow this similar (but surly not identical!) thread, I added a fifth value to the Path Environment variable, restarted the Win CLI, and than when I ran drush up at the sites' folder, I got another, brand new error:


  wget nor curl executables found.


I need to further explore this but if you have an idea, please shoot...

Drush is giving a very accurate error message


  wget nor curl executables found.


You can either install Curl separately as benos suggests above or install more Unix tools. Since you might need Git anyway, why not install Git for Windows? Then you get a proper Bash prompt. If you prefer to use Command or Powershell you can select to update the PATH variable when installing so Git (and the Unix tools) are available there too.
