 If using `brew update-python-resources` doesn't work, you can use [homebrew-pypi-poet](https://pypi.python.org/pypi/homebrew-pypi-poet) to help you write resource stanzas. To use it, set up a virtualenv and install your package and all its dependencies. Then, `pip install homebrew-pypi-poet` into the same virtualenv. Running `poet some_package` will generate the necessary resource stanzas. You can do this like:
 
 ```sh
-# Install virtualenvwrapper
-brew install python
-python3 -m pip install virtualenvwrapper
-source $(brew --prefix)/bin/virtualenvwrapper.sh
+# Use a temporary directory for the virtual environment
+cd "$(mktemp -d)"
 
-# Set up a temporary virtual environment
-mktmpenv
+# Create and source a new virtual environment in the venv/ directory
+python3 -m venv venv
+source venv/bin/activate
 
 # Install the package of interest as well as homebrew-pypi-poet
-pip3 install some_package homebrew-pypi-poet
+pip install some_package homebrew-pypi-poet
 poet some_package
 
-# Destroy the temporary virtualenv you just created
+# Destroy the virtual environment
 deactivate
+rm -rf venv
 ```
 
 Homebrew provides helper methods for instantiating and populating virtualenvs. You can use them by putting `include Language::Python::Virtualenv` at the top of the `Formula` class definition.
