Downgrading Python Version (If Needed)

If you encounter errors because your global Python version is too high (e.g., Python 3.13), you can downgrade to Python 3.12.8 using pyenv.

FACED Alot of ERROR ON Downgrading Python Version

• Error Encountered: I encountered errors because my global Python version was too new (Python 3.13.1) for some dependencies in the project.

• Solution: I used pyenv to downgrade my Python version to 3.12.8 as recommended by the Crew AI docs.

• I have the 3.13.1 python version installed on my system. I will install the required version of python using pyenv.

• SOLUTION FOR MacOS/LINUX:

1. First, install pyenv using the following command:

• For MacOS/Linux

  brew install pyenv
  

2. Now Install Python Version 3.12.8 using pyenv:.

  pyenv install 3.12.8

• Run this command in your project directory:

  pyenv local 3.12.8

3. Now Install pyenv-vitualenv

brew install pyenv-virtualenv

4. set up Shell Configuration

   echo 'if which pyenv > /dev/null; then eval "$(pyenv init --path)"; eval "$(pyenv init -)"; eval "$(pyenv virtualenv-init -)"; fi' >> ~/.zshrc
   source ~/.zshrc

5. Verify the Plugin Installation

   pyenv commands | grep virtualenv
   

6. Create the Virtual Environment

   pyenv virtualenv 3.12.8 crew_ai_env

SOLUTION For Windows if You have python 3.13 or later:

First open the command prompt as administrator then run the following command:

1. Install Chocolatey

   Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]::Tls12; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))
   

2. Install pyenv using Chocolatey:

   choco install pyenv --pre
   

3. Install the required version of python using pyenv:

pyenv install <specified python version>

like this:

pyenv install 3.12.8
pyenv install 3.9.12

Download the version of python you want to install and then install it.

3. Verify the installation:

   python --version

4. Refresh the terminal with this command to apply the changes:

pyenv rehash

5. Then install the c++ credentials using this link :

   • Now you will see this page:

   

6. Install the C++ build tools:

 - Click on the "Download" button.
 - Select the "Build tools for C++" option.
 - Choose the correct version of the build tools that matches your Python version.
 - Click on the "Download" button to download the build tools.

7. You have to tick the check box

   • MSVC v143 - VS 2022 C++ x64/x86Windows 10 SDK

   • You have to check this

   • Now you will see this page:

   • Click the check box to tick it.

8. Now Install Python Version 3.12.8 using pyenv:.

• For Windows:

  pyenv install 3.12.8

  • Run this command in your project directory:

    pyenv local 3.12.8

9. NOwW:

10. Navigate to the project directory

11. Run the following command in the command prompt:

    pyenv local 3.12.8

    This will set the local Python version to 3.12.8. in your project directory.

12. verify

    pyenv version # This should show Python 3.12.8

13. Create the virtual environment

    python -m venv myenv

    This will create a virtual environment named myenv in your project directory.USing python 3.12.8

Installing Crew AI

1. Install CrewAI: Install Crew AI with the recommended tools:

   pip install crewai crewai-tools
   
   

2. Upgrade CrewAI (If Needed):

   If you already have an older version, use:

   pip install --upgrade crewai crewai-tools
   
   

3. Verify the Installation:

   Run the following to check the installed versions:

   pip freeze | grep crewai
   

   You should see something like:

   crewai==0.95.0
   crewai-tools==0.25.8

Troubleshooting Tips

1. Python Version Compatibility: Ensure you're using a compatible version of Python (3.10 to 3.12). If you face issues, downgrade to a supported version using pyenv.

2. Environment Issues: If you encounter problems related to the virtual environment, always ensure that you're activating the correct one. You can check your environment with:

pyenv version

3. Missing Modules: If you get errors related to missing modules, verify that all dependencies are installed correctly with pip install.
