# 31. Setting Up a Virtual Environment In PyCharm¶

A Python virtual environment (venv) allows libraries to be installed for just a single project, rather than shared across everyone using the computer. It also does not require administrator privilages to install.

Assuming you already have a project, follow these steps to create a venv:

Step 1: Select File…Settings

Step 2: Click “Python Interpreter”. Then find the gear icon in the upper right. click on it and select “Add”

Step 3: Select Virtualenv Environment from the left. Then create a new environment. Usually it should be in a folder called venv in your main project. PyCharm does not always select the correct location by default, so carefully look at the path to make sure it is correct, then select “Ok”.

Now a virtual environment has been set up. The standard in Python projects is to create a file called requirements.txt and list the packages you want in there.

PyCharm will automatically ask if you want to install those packages as soon as you type them in. Go ahead and let it.
