Question

我正在尝试将venv用于我的项目，但无法正常工作。因此，首先我要激活我的venv，然后使用命令“ pip Frozen”来检查计算机中是否未安装任何模块。并且有一个输出^

user@DESKTOP-JMJSO6O C:\Users\user\Desktop\app\Scripts                                          
$ activate

$ pip freeze

bleach==3.1.0                                                                                     
bs4==0.0.1    
...

那是不正确的，因为我没有在该venv中安装任何模块。可能是什么问题？

UPD：使用venv尝试pip --version：

(app) user@DESKTOP-JMJSO6O C:\Users\user\Desktop\app\Scripts $ pip --version

version of pip. Please see github.com/pypa/pip/issues/5599 for advice on fixing the 
underlying issue. To avoid this problem you can invoke Python with '-m pip' instead 
of running pip directly. pip 20.0.2 from 
C:\Users\user\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\pip (python 3.8)

我也发现了另一个问题。例如，我在一个目录中有两个python文件：

- app/
    - main.py
    - conf.py

当我尝试将conf作为模块导入main.py时，出现错误： ModuleNotFoundError: No module named 'conf' 也许问题出在Windows？因为在装有Windows的笔记本电脑上，我没有类似的问题。

似乎此问题是由scanf的两个版本或更新尝试失败引起的。我建议您尝试遵循这些instructions。

或者尝试在虚拟环境的内部和外部运行String [] sentence ArrayList <String> sentenceList = new ArrayList <String> (); try { Scanner sentenceScanner = new Scanner (new File("data/" + fileName)); while (sentenceScanner.hasNextLine()) { sentenceList.add (sentenceScanner.nextLine()); } sentenceScanner.close(); } catch (FileNotFoundException e) { System.out.println ("File Not Found"); } for (int r = 0; r < sentenceArray.length; r++) { sentence = sentenceArray [r].split ("(?<=[.!?])\\s*"); for (int i = 0; i < sentence.length; i++) { System.out.println (sentence [i]); } }和pip并查找差异。

我希望您能解决这个问题，github线程表明问题仍然没有明显的解决方案。
