Installing External Packages
Reflex Build allows you to install external python packages to use in your app. This is useful if you want to use a package that is not included in the default Reflex Build environment. Examples might include openai
, langsmith
, requests
, etc.
There are two ways to install external packages:
- Through the Chat Interface: You can ask the AI to install a package for you.
- Add to the
requirements.txt
file: You can add the package to therequirements.txt
file and then save the app. This will install the package in your app's environment.
Installing through the Chat Interface
Enter the name of the package you want to install in the chat interface. The AI will then install the package for you.

Installing through the requirements.txt file
Add the package to the requirements.txt
file and then save the app. This will install the package in your app's environment and recompile your app.
