导入TextBlob时出错

Question

I am having a problem when running a Python script within my Laravel project. I do not get this problem when running the python script using virtualenv and without. I am using Win 10 64-bit.

When running the python script within Laravel using Symfony/Process, I am getting this error:

"""

"""

From what I understand is that nltk is a textblob dependency, however nltk/downloader.py is returning false at default_download_dir (but it should be true as I test the if condition in a python shell):

    # On Windows, use %APPDATA%
    if sys.platform == 'win32' and 'APPDATA' in os.environ:
        homedir = os.environ['APPDATA']

    # Otherwise, install in the user's home directory.
    else:
        homedir = os.path.expanduser('~/')
        if homedir == '~/':
            raise ValueError("Could not find a default download directory")

This is how textblob is declared on my main.py

from textblob import TextBlob

My other imports are not having any problem besides this specific package. I'm at a roadblock at this point so all help will be appreciated.

Answer 1

I got my answer from this post: ValueError: Could not find a default download directory of nltk

What I did is to initialize a NLTK_DATA environment variable within the py script. This solved the problem.

import os

os.environ['NLTK_DATA'] = os.path.abspath('../scripts/nltk_data')
