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

Question

我刚刚安装了Python 3.7和Fabric。

它在我的笔记本电脑上完美运行，但不在我的桌面上。

错误 ：

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

File "C:\python_project\myProject\fabfile.py", line 2, in <module>
from fabric.api import task, run, env, settings, hide
ModuleNotFoundError: No module named 'fabric.api'

但Fabric似乎已安装？

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

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

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

我也尝试卸载/重新安装结构，但它仍然失败。

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 . 

在Visual Studio代码中选择Python解释器“venv”然后：

python -m pip install fabric 

但我仍面临同样的错误： - /

Answer 1

经过一些研究，我终于通过使用fabric3（一个Fabric的分支，兼容的python 3）找到了一个解决方法。

pip uninstall fabric
pip install fabric3

Answer 2

我看到你已经安装了fabric 2.4.0这太棒了！由于您使用的是fabric 2.4.0，因此无法使用from fabric.api import taks。如果你使用fabric.api，可以使用fabric1xx

如果你想从fabric2.4.0导入连接和任务，你必须这样做

from fabric import Connection as connection, task

@task
def deploy(ctx):
    with connection(host=host, user=user) as c:
         c.run('ls -la')

注意：面料3不是官方分叉。我建议你使用fabric2.4.0
