This environmental variable looks good @eastonsuo but I would just make the change directly in blocks.py. Let me push the change here

[abidlabs]

Should be fixed now @eastonsuo. I confirmed that setting the GRADIO_ROOT_PATH environmental variable sets the default root path, but it can be overridden by the explicit root_path parameter in launch().

Test code:

import gradio as gr
import os

os.environ["GRADIO_ROOT_PATH"] = "/test"

gr.Interface(lambda x:x, "textbox", "textbox").launch(root_path="")

You can try out this branch by installing pip install https://gradio-builds.s3.amazonaws.com/e91525abc3076a91660643e3cf0a1cec15a3ec5e/gradio-3.39.0-py3-none-any.whl

Will merge in once CI passes.
