Failure when executing a executable builded by pyinstaller

I'm trying to use pyinstaller to build a executable with pyjulia, here is my code:
```python
from julia import Main

def hello(u = "world"):
Main.println(f"hello {u}!")

hello()
```

This works good in REPL, but runs into a error after pack it into a executable using pyinstaller:

```
PS D:\codehub\Instrument.jl\EC22.jl\temp\dist\hello> .\hello.exe
