Attributeerror: module asyncio has no attribute run error occurs because the lower versions of Python Interpreter ( less than 3.7 ) do not contain or define asyncio.run() function. If the code we are running contains asyncio.run() function as a part of syntax then if we run in a lower version of the python environment.
We mostly get this error while migrating the code across the environment. Suppose a developer developed some code in his local environment where he or she has Python 3.9 installed and now we the same code to production which is an old system (Python 3.4 series ) . Now if we directly do the same bypassing the testing properly for sure we will get this error. Anyway, let’s see how we can fix this error.
There are two broad solutions for this type of error. The first is fixing the environment on the basis of code and the second is fixing the code on the basis of the environment.
This is the easiest way to fix this error but it has some complications for example
Now the question arises of how to upgrade the Python version. So you can simply :
To install the newer Python version by uninstalling the lower version, we can simply download the latest or newer version from Python official website and reinstall the same.
Use the below command.
sudo apt update
sudo apt install python3.7
This is a specific solution for complications mentioned in Solution 1. If you can’t update the global Python interpreter version then create a virtual Python environment with the below command and run the code here.
python3.7 -m venv "my_env_name"
Here version you can alter as per your requirement.
In some cases, we can not upgrade our Python Interpreter Version and we are stuck with errors. In this type of scenario, we can use some alternative syntax. We can use get_event_loop() function to achieve the same functionality. Let me add a full example of this.
import asyncio
async def main():
if __name__ == "__main__":
holder= asyncio.get_event_loop()
holder.run_until_complete(main())
This is limited to version 3.3 of Python because onward version ( 3.4 later ), this asyncio module starts coming with the official release. So no external installation is required. Now let’s see how can we install or upgrade asyncio module quickly.
pip install asyncio
