Python - 没有名为“fabric.api”的模块 - Windows 10

Question

我刚刚安装了 Python 3.7 和 Fabric。

它在我的笔记本电脑上运行良好，但在我的台式机上运行不佳。

错误:

Traceback (most recent call last):
File "C:\Program Files (x86)\Python37-32\lib\runpy.py", line 193, in _run_module_as_main

ModuleNotFoundError: No module named 'fabric.api'

但是 Fabric 好像安装好了？

C:\Users\MyUser>pip install fabric
Requirement already satisfied: fabric in c:\program files (x86)\python37 32\lib\site-packages (2.4.0)

C:\Users\MyUser>pip show fabric

然而，当我在空闲时执行以下操作(只是 Fabfile)时，“fabric”没有出现在列表中:

>>> import pkgutil
>>> [name for _, name, _ in pkgutil.iter_modules()]
['fabfile', '_asyncio', '_bz2', ... 'enum', 'filecmp', 'fileinput', ...]

我也尝试过卸载/重新安装 fabric，但仍然失败。

你知道为什么我不能导入 fabric.api 吗？

更新:

我还创建了一个虚拟环境:

py -3 -m venv env 
code . 

然后在 Visual Studio 代码中选择 Python 解释器“venv”:

python -m pip install fabric 

但我仍然面临同样的错误:-/

Answer 1

经过一些研究，我终于找到了使用 fabric3(Fabric 的一个分支，兼容 python 3)的解决方法。

pip uninstall fabric
pip install fabric3
