安装portia时发生安装错误

Question

Followed instructions on the github page. Of course, had to make minor changes since I was working with a windows 7 system. I got to the point post creating the virtual environment for portia to run. And I was trying to install the required packages using pip.

pip install -r requirements.txt

It failed with a log .

Now in the shell I try to run twistd, it gives error saying command not found. I even tried as follows:

deostroll@DEOTOP /c/Portia/portia/slyd (master)
$ python ../../portia_env/Scripts/twistd.py -n slyd
Traceback (most recent call last):
  File "../../portia_env/Scripts/twistd.py", line 13, in <module>
    from twisted.scripts.twistd import run
  File "c:\Portia\portia_env\lib\site-packages\twisted\__init__.py", line 53, in
 <module>
    _checkRequirements()
  File "c:\Portia\portia_env\lib\site-packages\twisted\__init__.py", line 37, in
 _checkRequirements
    raise ImportError(required + ": no module named zope.interface.")
ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zop
e.interface.
(portia_env)
deostroll@DEOTOP /c/Portia/portia/slyd (master)
$

Is there an alternate procedure to follow in order to make this work on windows?

Answer 1

It looks like zope.interface didn't install when you ran:

pip install -r requirements.txt

Could you try running the following and see if it works?

pip install zope.interface
