Issue Content

`app = FastAPI()
base_dir = os.path.dirname(os.path.abspath(file))

Full paths for static and templates directories

static_dir = os.path.join(base_dir, "app/static")
templates_dir = os.path.join(base_dir, "app/templates")

Mount the 'static' directory to serve static files

app.mount("/static", StaticFiles(directory=static_dir), name="static")
app.mount("/templates", StaticFiles(directory=templates_dir), name="templates")

app.include_router(auths.auth)

if name == "main":
import uvicorn
uvicorn.run(app, host="0.0.0.0", port=8000)`

Application is running well through uvicorn or python main.py or fastapi dev

but i am trying to make build of my application through pyinstaller (command is below)
pyinstaller -F --onefile main.py

and when i am commenting the app.mount lines then the build is working fine, only it is giving below error for app.mout
