我已經研究這個腳本幾個星期了，我剛剛完成，一切都運行良好。我返回腳本并嘗試運行它，但我遇到了一個錯誤并且知道它的含義以及如何解決它。當我下載一些包含 CoronaVirus 數據的 csv 文件時，腳本很早就出現了錯誤。我正在使用 urllib.request 來執行此操作，但出現錯誤 File "Run.py", line 13, in <module> urllib.request.urlretrieve(url, filename="time_series_covid19_recoveredGlobal.csv") File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 247, in urlretrieve with contextlib.closing(urlopen(url, data)) as fp: File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 222, in urlopen return opener.open(url, data, timeout) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 525, in open response = self._open(req, data) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 542, in _open result = self._call_chain(self.handle_open, protocol, protocol + File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 502, in _call_chain result = func(*args) File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 1362, in https_open return self.do_open(http.client.HTTPSConnection, req, File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/urllib/request.py", line 1322, in do_open raise URLError(err)urllib.error.URLError: <urlopen error [Errno 8] nodename nor servname provided, or not known>

您的網址有拼寫錯誤：
而不是域是githubuserxxxent.com，他們應該是githubusercontent.com。
請注意，嘗試在瀏覽器中訪問它時githubuserxxxent.com會返回錯誤。Address not found
也許您在代碼中進行了查找和替換，這就是發生這種情況的原因。
固定代碼：
import urllib.request
url = "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_covid19_recovered_global.csv"
urllib.request.urlretrieve(url, filename="time_series_covid19_recoveredGlobal.csv")
url = "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_covid19_confirmed_global.csv"
urllib.request.urlretrieve(url, filename="time_series_covid19_confirmed_global.csv")
url = "https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_time_series/time_series_covid19_deaths_global.csv"
urllib.request.urlretrieve(url, filename="time_series_covid19_deaths_global.csv")
