Route already registered: /swagger/<file_uri:/?.+> [GET,HEAD]

sanic 20.12.2
sanci-openapi 0.6.2
centos 7.4

When I run my project through pycharm all work fine, but when I package my project through pyinstaller and try to run the exe it cracks with the message that

File "sanic/app.py", line 718, in blueprint   
File "sanic/blueprints.py", line 151, in register

sanic.router.RouteExists: Route already registered: /swagger/<file_uri:/?.+> [GET,HEAD]

I have seen #216 but it doesn't seem to help.

Thanks for the report, i don't know about this one but one thing I can see which might help you is that your sanic version is outdated, could try version 20.12.3 which is the latest from the 2012 release,

would also recommend to try with sanic 18.12 and sanic 21.3 and see if either of those work

if not i could help you debug it if you share a small code sample which can recreate it

Will close this but please do re-open if that doesn't solve your problem

I've tried your suggestion but it didn't work.
The code is as below:

# sanic-openapi-test.py
from sanic import Sanic
from sanic.response import json
from sanic_openapi import swagger_blueprint

app = Sanic(name="sanic_openapi_test")
app.blueprint(swagger_blueprint)


@app.route("/")
async def test(request):
    return json({"hello": "world"})


if __name__ == "__main__":
    app.run(host="0.0.0.0", port=8000)

And I packaged the code by PyInstaller (pip install pyinstaller)

 pyinstaller sanic-openapi-test.py

Went into the dist directory that is made by the command above and ran the sanic_openapi_test.exe. The error appeared:

Traceback (most recent call last):

sanic_routing.exceptions.RouteExists: Route already registered: swagger/<__file_uri__> [GET]

Hope you can help me solve this problem. Thanks!
