import nltk Not working in Python (nltk and numpy successfully installed, pip working)

Question

我已經在這里解決了這個問題的許多版本，但我仍然找不到答案或弄清楚為什么import nltk在 Python 中不起作用。我有 Windows 10，我卸載並重新下載了這兩個 32 位版本和 Python 的 64 位版本（目前我只安裝了 64 位版本），這就是我的命令提示符的樣子：

(base) C:\Users\Cathryn>py -3.8-32 -m pip install -U nltk

然而，當我將import nltk放入 Python IDLE 和 Python window 看起來像 windows 命令提示時，會發生這種情況：

>>> import nltk
Traceback (most recent call last):
  File "<pyshell#6>", line 1, in <module>
    import nltk
ModuleNotFoundError: No module named 'nltk'
>>> 

除了使用 64 位版本而不是推薦的 32 位版本之外，我遵循了https://www.nltk.org/install.html上的所有說明。 我像建議的其他答案一樣下載了 Anaconda 。 我真的不知道是什么導致了這個問題，我將不勝感激任何幫助。

如果沒有別的，感謝您閱讀到這里。

Answer 1

您的編輯器可能使用了錯誤的解釋器。 它必須指向作為基礎環境的“PathToAnaconda\python.exe”。

Answer 2

因此，您的 IDLE 使用的是 python 3.9，但您在 python 3.8 上安裝了 nltk。

你可以試試

py -3.9 -m pip install nltk

從命令提示符然后嘗試再次從 IDLE 導入 nltk。
