![]() If you are coming from node package manager background then pyenv is similar to nvm which allows us to work with different python versions whereas pipenv is analogous to npm with batteries. There are different ways to accomplish this, however I am using pyenv and pipenv If working locally on several Python projects, you may need to use different Python versions on each. You are done setting the PYTHONPATH on your Linux system.A Python virtual environment is an important tool for development when separating project dependencies in isolated environments. It will show something like /home/my_user/code: Step 6: Restart the terminal application. Step 3: In this text editor, add this line at the end: Step 2: In your text editor, open the ~/.bashrc file. To set the python environment variable PYTHONPATH on Linux, follow the given steps: Setting the Python Environment Variable PYTHONPATH on Linux It would show something like /Users/my_user/code. Step 3: To this file, add the following line at the bottom: Step 2: In your text editor, open the ~/.bash_profile file. To set the python environment variable PYTHONPATH on Mac, follow the given steps: Setting Python Environment Variable PYTHONPATH on Mac In the next section, we will examine how you can set the PYTHONPATH environment variable on different operating systems. In layman's terms, the Python interpreter cannot find the location of the sample.py file. We get such an output because the PYTHONPATH has not been set yet. ModuleNotFoundError: No module named 'sample' The script sample_script.py has the following content:įile "scripts/sample_script.py", line 1, in The module sample.py has the following content: So, with PYTHONPATH, users can import modules that have not been made installable yet. PYTHONPATH variable includes various directories as a string to be added to the sys.path directory list. ![]() It also handles the default search path for modules in Python. In simple terms, it is used by user-defined modules to set the path so that they can be directly imported into a Python program. So, the only reason to use PYTHONPATH variables is to maintain directories of custom Python libraries that are not installed in the site packages directory (the global default location). ![]() As these variables are not needed for Python to run, they are not set for most installations. Understanding the Pythonpath Environment Variable inĪn environment variable that lets you add additional directories where Python looks for packages and modules. ![]() It is available to all programs running in the same environment. PYTHONPATH is one such environment variable that is, it is a key-value pair stored in a computer's memory. Environment variables influence the behavior of Python. ![]()
