C:\> python3 -m venv --system-site-packages ./venv

• You can activate the virtual environment by typing the following code:

C:\> .\venv\Scripts\activate

For macOS:

• You can create the virtual environment by opening the command prompt and typing the following code:

$ python3 -m venv --system-site-packages ./venv

• You can activate the virtual environment by typing the following code:

$ source ./venv/bin/activate

$ pip install rasa-x --extra-index-url https://pypi.rasa.com/simple

5- Install Rasa NLUand Spacy in the same command prompt:
