Hi All, I posted my question before the holidays but i got not reply. Can someone please point me in the right direction? I am having some problems with my tool dependencies to setup a python venv. Dependencies.xml looks like this: [X] [X][cid:7b48a44d-07dd-4838-8f90-5024d9d22593] When i install my tool from the toolshed, it fails to install the venv dependency with this error message: [X][cid:0f2c174a-5011-423f-9eaf-ef2ed88c353d] I am not sure what the problem exactly seems to be. os.py should be a default python package right or do i need to specify it in the dependencies file? Together with our system administrator, we have been trying to solve the issue, but no luck so far. Is my dependencies.xml file ok?
