Action which sets up virtual environment for the provided packs. |

Setup consists of the following step: |
|
31
|
|
|
|
|
32
|
|
|
1. Create virtual environment for the pack |
|
33
|
|
|
2. Install base requirements which are common to all the packs |
|
34
|
|
|
3. Install pack-specific requirements (if any) |
|
35
|
|
|
|
|
36
|
|
|
If the 'update' parameter is set to True, the setup skips the deletion and |
|
37
|
|
|
creation of the virtual environment and performs an update of the |
|
38
|
|
|
current dependencies as well as an installation of new dependencies |
