Python 为什么我缺少库“stdlib_列表”中的一个文件？

我安装了一个名为

stdlib\u list

当我执行以下代码时，我得到一条错误消息

import importlib
from stdlib_list import stdlib_list
x = iter(stdlib_list())

错误消息：

Traceback (most recent call last):
  File "D:/FILE_MGMT_PYTHON/common_function_names.py", line 4, in <module>
    x = iter(stdlib_list())
  File "C:\Users\Sam\AppData\Local\Programs\Python\Python38-32\lib\site-packages\stdlib_list\base.py", line 44, in stdlib_list
    with open(module_list_file) as f:
FileNotFoundError: [Errno 2] No such file or directory: 'C:\\Users\\Sam\\AppData\\Local\\Programs\\Python\\Python38-32\\Lib\\site-packages\\stdlib_list\\lists\\3.8.txt'

Process finished with exit code 1

这个答案的所有功劳都归于

stdlib_list

模块自动查找当前使用的python版本，并尝试打开与之对应的文件a。目前还没有Python3.8的文件。解决方案是将较旧的版本号传递给

stdlib_list（）

，例如

stdlib_list（'3.6'）

，并获取该版本的列表。

stdlib_list模块包含各种Python版本中包含的标准模块列表。它显然还没有Python3.8的列表。您可以将一个显式的较旧版本号传递给

stdlib_list（）

-

stdlib_list（'3.6'）

），然后获取该版本的列表，尽管这实际上可能对您没有任何用处。

C:\Users\Sam>C:\Users\Sam\AppData\Local\Programs\Python\Python38-32\python.exe -m pip install stdlib_list --user

Requirement already satisfied: stdlib_list in c:\users\sam\appdata\local\programs\python\python38-32\lib\site-packages (0.5.0)
