Best practices to keep crewai active venv in sync with project venv?

CrewAI Community Support

Hi, has this been fixed recently?

  1. When you install crewAI you get the libraries added to the current active virtual-env, as it should be.
  2. But then when you create a crewAI project, you get a second virtual-env at the project level.

Because of this, if you ever update the active environment with a new version of crewAI then the second virtual-env at the project level gets out of sync. And you get the obnoxious warning: VIRTUAL_ENV=/.... does not match the project environment path .venvand will be ignored; use–active` to target the active environment instead

What is the right solution for this problem?

Hi @zinyando, Do you have any thoughts on how to deal with this problem?

Hi Alfred, I haven’t run into this problem before. Are you getting this issue when using crewai CLI commands or you are using other methods to run your crews?

Can you describe your project setup?

@zinyando
The problem is when I use the CrewAI CLI. I have a virtual env. before installing crewAI ( .venv_crewai ) and then crewAI will create a new virtual env. inside the project ( .venv ) . Is it expected to end up with these two virtual envs?

…
.venv_crewai ← virtual env that has crewAI libraries
.gitignore
my_project/
├── .venv ← virtual env inside the project
├── .gitignore
├── knowledge/
├── pyproject.toml
├── README.md
├── .env
└── src/

I am facing the similar issue since last 2 days. I do not understand the root folder is marked as .venv (library root) with Python 3.12.4 but whenever I run “crewai create crew my_crew”, it is created correctly with proper folder structure. However when I do “crewai run” it is creating another .venv file within that project with python version 3.13. Because I could see , in Environmental Variables, I have mentioned 3.13\scripts and 3.12\scripts respectively. On searching further I could understand that when “crewai run” command is executed, UV is creating a new .venv ignoring its root .venv. And since the project level .venv and root level .venv are mismatched, on running I am getting a warning every time followed by an error message throwing that ‘nomodulefounderror’. Kindly suggest what to do! Is there any issue keeping multiple python versions in my system! I had to install another version (python 3.12) since one of my applications does not allow 3.13 version support, so I have to keep both the version. My IDE is Pycharm.
