LaunchD Job失敗的怪異原因：2

我一直在嘗試使用launchD來每24小時執行一次腳本，但是我一直接收奇怪的原因錯誤：2;我知道這意味着該文件沒有找到，但我檢查並進行了雙重檢查，以確保程序參數中的文件路徑是正確的。當我在終端中執行腳本時，腳本運行良好。任何想法爲什麼這不起作用？LaunchD Job失敗的怪異原因：2

該腳本只是從AngelList中刪除新添加的啓動信息並通過電子郵件發送出去。

下面是我的launchd和Python腳本：

Python:

    db = client.tiger_labs 
    collection = db.new_startups 
    existing_names = [] 
    for startup in collection.find(): 
     existing_names.append(startup.get('name')) # inserts all "already-found" startups to the database 

    market_tags = ["mobile health", "health care", "health care information technology", "health and wellness", "personal health"] # lists out all tags
