Python get package dir

Find the Location of Python site-packages Directory

How do I find the location of my Python site-packages directory? The “site-packages” directory is where third-party packages are installed for Python. In this article, we will explain different methods to find the location of the “site-packages” directory.

A quick way to find the “site-packages” directory is by using the site module. You can simply import the module and use the getsitepackages() function to get the “site-packages” directory. However, we will discuss more methods like, the sys module, the os module, and the distutils package with examples.

1. site Module to Find Directory of Python Site-Packages

The site module allows you to access the python interpreter and the installed packages, one of the functions provided by the site module is getsitepackages() , which returns a list of directories that contain the installed packages, including the “site-packages” directory.

See the following code example:

 # Import site module import site # Get the list of directories site_packages_dirs = site.getsitepackages() # Find the "site-packages" directory in the list for dir in site_packages_dirs: if dir.endswith("site-packages"): target_dir = dir break else: target_dir=None print(target_dir) 

 # Output: c:\Users\Ali\Desktop\SparkByExamples\env\Lib\site-packages 

There are two types of python “site-packages” directories. One is called the global site-packages directory and the virtual environment “site-packages”.

You can run the following command on your terminal to find the directory of python global site-packages.

 # Find Location of Global "site-packages" python -m site 

 # Output: c:\Users\Ali\AppData\Local\Programs\Python\Python311\Lib\site-packages 

This will return the location of the global directory of python “site-packages”. You can also add another parameter to get the location per user.

 #Find Location of Per-user "site-packages" python -m site --user-site 

2. sys Module – Python Site-Packages Directory

The sys module is another way to access various system-specific parameters and functions. One of the attributes provided by the sys module is path , which is a list of directories that Python searches for modules.

 # Find the "site-packages" directory in the "sys.path" list import sys # Iterate over the Directories for dir in sys.path: if dir.endswith("site-packages"): target_dir = dir else: target_dir = None print(target_dir) 

 # Output: c:\Users\Ali\Desktop\SparkByExamples\env\Lib\site-packages 

3. Using os Module

The os module is a built-in module in Python that provides a way to interact with the operating system. The os module provides several functions for navigating the file system and getting information about files and directories. One of these functions is listdir() which returns a list of the files and directories in a specified directory.

 # Using os to get the Location import os dir_path = os.path.dirname(os.__file__) + '/site-packages' print(dir_path) 

 # Output: C:\Users\Ali\AppData\Local\Programs\Python\Python311\Lib\site-packages 

4. distutils – Find Directory of “site-packages”

The distutils module in Python provides support for building and distributing Python modules. It includes a sysconfig module, which provides functions for retrieving configuration information about the Python installation.

 # distutils library to get the location of Python "site-packages" from distutils.sysconfig import get_python_lib site_packages_dir = get_python_lib() print(site_packages_dir) 

 # Output: c:\Users\Ali\Desktop\SparkByExamples\env\Lib\site-packages 

The sysconfig is also available is a standalone module, which you can use directly instead of importing it from the distutil .

 # Using the sysconfig module import sysconfig print(sysconfig.get_paths()) 

The location return by the sysconfig on Debian seems like to be not available, this is because when you install packages using pip, it will go into ‘dist-packages’ and not to ‘site-packages’.

5. Use Editor – The Optimal and Easy Way

If you are using a virtual environment for your project, you can find the python site packages in the editor. The editor maybe is of your choice. In my case, I am using VS code and my virtual environment is “env”. You can see the complete path to the “site-packages” directory.

6. Summary and Conclusion

In this article, we have learned how to find the location of the python “site-packages” directory. You have learned multiple ways to do this. If you are working in VS Code or any other editor along with a virtual environment, this directory is already available to you. Hope this article was helpful.

Where Does pip Install Packages

To see where pip installs packages on your system, run the following command:

And replace with the actual name of the package.

Example: NumPy Location

For example, let’s see where NumPy is installed:

Name: numpy Version: 1.22.2 Summary: NumPy is the fundamental package for array computing with Python. Home-page: https://www.numpy.org Author: Travis E. Oliphant et al. Author-email: None License: BSD Location: /usr/local/lib/python3.8/site-packages Requires: Required-by: torchvision, perfplot, opencv-python, matplotx, DALL-E, benchit

Here you can see that the location field says the package is installed at /usr/local/lib/python3.8/site-packages.

The location obviously depends on your system and Python version.

How to View All pip Package Locations

To list all the installed package locations, run the following command:

This spits out a huge list of different packages and their locations:

alabaster 0.7.8 /usr/lib/python3/dist-packages apparmor 2.13.3 /usr/lib/python3/dist-packages appdirs 1.4.3 /usr/lib/python3/dist-packages apturl 0.5.2 /usr/lib/python3/dist-packages .

Now you understand how to check the pip package locations using the command line/terminal.

Next, let’s take a look at how you can find this information using a Python script.

How to View pip Package Location in Python Script?

In addition to using the command line to figure out the location of packages installed via pip, you can run a Python script to get the information.

There are two ways to do this:

The site Module

To find the general location of pip packages in a Python script:

1. Import the site package.
2. Call the getsitepackages() function of the module.
3. See a list of global package locations.

Here is how it looks in code:

>>> import site >>> site.getsitepackages() ['/usr/local/lib/python3.8/dist-packages', '/usr/lib/python3/dist-packages', '/usr/lib/python3.8/dist-packages']

And to get a user-specific package location as a string, call the getusersitepackages() function instead.

The help() Function

Of course, you can always use the help() function to get all kinds of information about any Python package or object.

This also shows you the location where the package is installed.

For example, lets’ see where the pandas package is installed:

>>> import pandas >>> help(pandas)

Running this piece of code opens up the package-specific manual.

If you scroll all the way down to the end of this output, you can see the FILE section where it shows you the path of the package.

By the way, in case you happen to be unfamiliar with the help() function in Python, I highly recommend you read this article. Using help() can help you a lot and save valuable coding time!
