The command you provided, "pickle install ${extension_name}", does not seem to be a valid command. It seems like there might be a typo or misunderstanding.
Assuming you are referring to the "pickle" library in Python which is used for serializing and deserializing Python objects, here is the correct way to install it:
To install the "pickle" library, you can use pip, the package installer for Python. Open your command line interface (CLI) and execute the following command:
pip install pickle
This will download and install the "pickle" library from the Python Package Index (PyPI) into your Python environment.
Replace ${extension_name}
with the actual name of the extension you want to install, if your intention was to install a different package. Note that the command structure might vary depending on the package manager you are using (e.g., pip, conda, npm in the case of JavaScript, etc.).
