執行問題

[yuyu0520]

你好~正在學習pecan框架，想利用你的code來做範本練習，請問一下執行指令是pecan serve config.py嗎?執行時有碰到以下錯誤代碼:
Traceback (most recent call last):
File "/home/may/venv/lib/python3.8/site-packages/pecan/configuration.py", line 110, in getattr
return self.values[name]
KeyError: 'server'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/home/may/venv/bin/pecan", line 11, in
load_entry_point('pecan', 'console_scripts', 'pecan')()

試著用cmd/api.py執行，也會有以下問題:
python api.py
Traceback (most recent call last):
File "api.py", line 13, in
main()
File "api.py", line 8, in main
application = app.setup_app()
TypeError: setup_app() missing 1 required positional argument: 'config'

查看setup_app() func並不需要帶任何參數，請問是我有缺少什麼參數嗎?
