這個小Python包有什麼問題？

Question

我想在Python上構建一個簡單的記號器包。但是當我嘗試在虛擬環境中本地安裝後運行它時，它拒絕導入。

pip install git+https://github.com/djokester/tokenizer 

然後

>>> import tokenizer 

Traceback (most recent call last): File "", line 1, in ImportError: No module named 'tokenizer'

能否請你告訴我，什麼是錯的包。 這裏是鏈接 https://github.com/djokester/tokenizer

Answer 1

該模塊的名稱是tokenize，而不是標記器。以下作品。

/ # pip install 'git+https://github.com/djokester/tokenize' --upgrade
