我想下載一個大的遠程文件，並得到一個新的錯誤..我從來沒有見過這個，我嘗試的URL，當我把它放到我的瀏覽器。dev_appserver.py中的App引擎URLError下載錯誤。 「不能分配請求的地址」
我請求URL用：
startDownloadTime = datetime.datetime.now()
logging.info("Download Start Time: "+startDownloadTime.strftime("%H:%M.%S"))
url = [MY URL]
logging.info("Starting download")
r = requests.get(url)
logging.info("Download complete")
以下是完整的跟蹤：
URLError: <urlopen error [Errno 99] Cannot assign requested address>

這是一個大的文件，所以我發現自己不得不使用套接字以下載它，所以這個app.yaml文件有：
env_variables:
GAE_USE_SOCKETS_HTTPLIB : 'anyvalue'
在裏面。有任何想法嗎？
編輯：只是想補充一點，這是特定於本地開發服務器，並在我的生產代碼工作。
編輯2：我想補充 - 腳本作品幾分鐘崩潰了所以好像它試圖下載一個文件之前..
