hello @gq_g

You can’t import packages which are not listed in the pyodide:

@barn4k we used to be able to import external packages thru micropip.install()

Now its throwing this error

Isnt it better to try something like adding an env variable to import specifics packages?

Just like this env but its for js

NODE_FUNCTION_ALLOW_EXTERNAL=axios,qs

NODE_FUNCTION_ALLOW_BUILTIN=*

not for the python :slight_smile:
