未找到Pip成功安装的模块：ImportError:没有名为xlwt的模块

Question

我的操作系统：赢10

已安装：

• python 2.7（命令为python）
• python 3.9.5（命令为python3）
• pip，pip3（两个都是python3，似乎都是）

pip命令：

c:\>pip3 config list -v
For variant 'global', will try loading 'C:\ProgramData\pip\pip.ini'
For variant 'user', will try loading 'C:\Users\luelue\pip\pip.ini'
For variant 'user', will try loading 'C:\Users\luelue\AppData\Roaming\pip\pip.ini'
For variant 'site', will try loading 'c:\users\luelue\appdata\local\programs\python\python39\pip.ini'

c:\>pip config list -v
For variant 'global', will try loading 'C:\ProgramData\pip\pip.ini'
For variant 'user', will try loading 'C:\Users\luelue\pip\pip.ini'
For variant 'user', will try loading 'C:\Users\luelue\AppData\Roaming\pip\pip.ini'
For variant 'site', will try loading 'c:\users\luelue\appdata\local\programs\python\python39\pip.ini'

我通过pip安装了xlwt，我可以看到它已安装：

c:\>pip install xlwt
Requirement already satisfied: xlwt in c:\users\luelue\appdata\local\programs\python\python39\lib\site-packages\xlwt-1.3.0-py3.9.egg (1.3.0)

然而，当我尝试导入它时，得到了错误：No module named xlwt

c:\>python
Python 2.7.15 (v2.7.15:ca079a3ea3, Apr 30 2018, 16:30:26) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import xlwt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named xlwt
>>> exit()

此外，我成功地使用了pip3 install xlwt，但运行python3 ... import xlwt失败。完整日志：

如何解决这个问题

我应该为python/pip配置windows路径还是什么

谢谢

编辑：

也许我安装了多个python3：

在python控制台中，您的python版本是2.7。 更改为python 3.9版本
