烧瓶导入错误和Anaconda

Question

I am having trouble running a Flask script. I get the following error:

Traceback (most recent call last):
  File "sample.py", line 17, in <module>
    from flask import Flask, make_response, render_template, request
ImportError: No module named flask

The thing is I am under Windows currently and flask is installed with pip install Flask . I am assuming the ImportError: No module named flask it's because the module is installed in the C:\\User\\Anaconda\\Lib\\site-packages directory and thus cannot be found by the Python interpreter:

Python 2.7.8 (default, Jun 30 2014, 16:03:49) [MSC v.1500 32 bit (Intel)] on win 32

Any suggestions on how to resolve the issue?

Answer 1

尝试使用conda安装flask： conda install flask

Answer 2

Do you have multiple versions of Python installed?

Commonly there's a system Python, then a local Python -- if a module is installed in #1, it won't be visible in #2.

Consider using virtualenvwrapper -- it helps with custom Pythons and modules. http://blog.fruiapps.com/2012/06/An-introductory-tutorial-to-python-virtualenv-and-virtualenvwrapper
