Check where python package is installed
I realize this answer is 4 years late, but the existing answers are misleading people. Show
The right way to do this is never It's the Unless you want to learn and implement the rules (which are
documented, but painful, for CPython 2.x, and not documented at all for other implementations, or 3.x) for mapping Meanwhile, every Python version's source from 2.0+ is available online at The Pip, Pipenv, Anaconda Navigator, and Conda Package Managers can all be used to list installed Python packages. You can also use the ActiveState Platform’s command line interface (CLI), the State Tool to list all installed packages using a simple “state packages” command. For a complete list of all packages and dependencies (including OS-level and transitive dependencies, as well as shared libraries), you can use the Web GUI, which provides a full Bill of Materials view. Give it a try by signing up for a free ActiveState Platform account. Before getting a list of installed packages, it’s always a good practice to ensure that up-to-date versions of Python, Pip, Anaconda Navigator and Conda are in place. List Installed Packages with PipBoth pip list and pip freeze will generate a list of installed packages, just with differently formatted results. Keep in mind that pip list will list ALL installed packages (regardless of how they were installed). while pip freeze will list only everything installed by Pip. For example: pip list Output: Package Version ---------------------------------- ---------- absl-py 0.7.0 pip freeze Output: absl-py==0.7.0 List Packages in a Console with PipTo list all installed packages from a Python console using pip, you can utilize the following script: >>> import pkg_resources installed_packages = pkg_resources.working_set installed_packages_list = sorted(["%s==%s" % (i.key, i.version) for i in installed_packages]) print(installed_packages_list) Output: ['absl-py==0.7.0', 'adodbapi==2.6.0.7', 'alabaster==0.7.12', 'alembic==1.0.7', 'amqp==2.4.1', 'anyjson==0.3.3', List Modules in a Console without PipTo list all installed modules from a python console without pip, you can use the following command: >>> help("modules") Note that there are some drawbacks to this approach, including:
List Installed Packages with PipenvThe pipenv lock -r command can be used to generate output from a pipfile.lock file in a pipenv environment. All packages, including dependencies will be listed in the output. For example: pipenv lock -r Output: -i https://pypi.org/simple certifi==2019.11.28 chardet==3.0.4 idna==2.9 requests==2.23.0 urllib3==1.25.8 List Installed Packages with Anaconda NavigatorTo list installed packages in an Anaconda environment using Anaconda Navigator, do the following:
List Installed Packages with CondaThe conda list command can be used to list all packages in a conda environment: conda list Output: # packages in environment at C:\Anaconda2_4.3.1: # _license 1.1 py27_1 alabaster 0.7.9 py27_0 Globally vs Locally Installed PackagesFor information about generating a list of installed packages globally vs locally, refer to: How to List Globally Installed Packages vs Locally Installed Packages in Python List Installed Packages with the ActiveState PlatformTo view a list of installed Python packages in your currently active project using the ActiveState Platform, run the following command on the command line: state show packages The output is a full list of installed packages in your current project: matplotlib numpy pandas scikit-learn scipy You can also obtain a complete software bill of materials view of all packages, dependencies, transitives dependencies (ie., dependencies of dependencies), OS-level dependencies and shared libraries (ie., OpenSSL) using the ActiveState Platform’s Web GUI: How do you find where my Python packages are installed?When a package is installed globally, it's made available to all users that log into the system. Typically, that means Python and all packages will get installed to a directory under /usr/local/bin/ for a Unix-based system, or \Program Files\ for Windows.
How do I find out what Python modules are installed?To check all the installed Python modules, we can use the following two commands with the 'pip': Using 'pip freeze' command. Using 'pip list command.
