我在 python 脚本中从 conda 导入包是否错误？

Question

嘿嘿！我知道这可能看起来像this question 的重复问题，但有一点不同。我想导入整个包，而不仅仅是一个或一组函数。当我从 Anaconda 导入包并尝试将它们导入 python 脚本时，我得到ErrorModuleNotFound。我可能导入错误，所以这里是信息：

• 我正在使用Python 3.6 和conda 4.3.21。

• Anaconda 包可以在这个目录中找到：C:\ProgramData\Miniconda3

• 我在 Anaconda Prompt 中输入的内容：pip install wikipedia （安装成功...）

• 我的 Python 脚本目录：C:\Users\aglin\Desktop\test.py

• Conda 环境列表：root * C:\ProgramData\Miniconda3

• Python.exe C:\Users\aglin\AppData\Local\Programs\Python\Python36-32\python.exe 和 C:\ProgramData\Miniconda3\python.exe 的路径

我的 Python 脚本包含的内容：

import wikipedia
print (wikipedia.summary("Windows OS"))
win = wikipedia.page("New York")
win.content

我得到的错误：

================== RESTART: C:\Users\aglin\Desktop\test.py ==================
Traceback (most recent call last):
  File "C:\Users\aglin\Desktop\test.py", line 1, in <module>
    import wikipedia
ModuleNotFoundError: No module named 'wikipedia'

我的问题：如何导入包wikipedia 而不出现此错误？如果有帮助，可以在here 找到“用于 Python 文档的 Wikipedia API”。另外，我对 Python 还很陌生，所以如果我需要做任何具体的事情或查看文档，请告诉我。谢谢！ :D

Answer 1

以下是在 conda 中创建环境的常用步骤，将 Python 版本放入其中，然后将库导入其中。

步骤如下：

• conda create --name Py36 python=3.6
• 激活 Py36
• pip 安装维基百科

您会注意到，在显示结束时，可以打开 Python 解释器并导入维基百科。
