I'm using Crypto.Cipher.AES in a django project ,but get this error.
I've installed pycrypto 2.6.1 with pip and it really exists on my disk,Pycharm does not show any errors and AES.py can be viewed.
My PC is windows 10,python version is 3.5.1, and django is 1.9.6.
I'm confused and find no solutions. Thanks in adcance!
This seems like it could be one of two problems:
An import conflict, i.e. there is another module/file named Crypto that
python is attempting to import.
The path to your module isn't in sys.path.
To solve 1, check the full import error stack trace to find where the Crypto.Cipher.AES is trying to import from, this should match the path of your Crypto module. Also check for any files/folders with the name Crypto that would cause an import collision in your application.
To solve 2, check your sys.path:
import sys
print sys.path
This is where the system looks when trying to import a module. If the exact path or root path to your module doesn't exist within this list, then the module will not be found.
You can add a path using the following:
sys.path.append('path/to/your/module')

I'm fairly new to python, but can't seem to get my head around this error - have found posts with similar issues, but none of the responses have helped.
I'm running Python 3.4.0 and have installed a module called lxml.
I wrote some code which starts
from lxml import html
This runs perfectly well from the python.exe interface, and the module can be used to succesfully import and parse XML.
However, if I save the script as a *.py file, and try to call it from a cmd.exe prompt, I get the ImportError: No module named lxml error.
Python is within C:\Python34, and the relevant module is located in C:\Python34\Lib\site-packages\lxml, which contains the required __init__.py
file.
I've checked sys.path which, amongst others, holds C:\\Python34\\lib\\site-packages
The double-backslashes and lowercase 'l' in 'lib' shouldn't make a difference, should it? All listed paths appear to have double-backslashes instead of single.
I did attempt to add the path with an uppercase 'L' using
sys.path.insert(1, 'C:\Python34\Lib\site-packages')
which subsequently appeared as a seperate path, however did not resolve the issue.
Additionally, I replaced the first line of my script with
import sys
sys.path.append('C:\Python34\Lib\site-packages')
which appeared to attempt to read the required __init__.py file (progress!!!), but then gave the following error: ImportError: Module use of python34.dll conflicts with this version of Python, so I probably won't pursue this avenue, unless it is of relevance.
Any idea what I'm doing wrong with regards to ImportError: No module named lxml?
I am not seeing an answer to this out there, so apologies if this is a duplicate. Basically, I am trying to understand how to force my interpreter (2.7) to import a module from site packages if there is a conflict. For example imagine you are running python from a directory (top_level) that has the following structure:
top_level
----cool_mod
----init.py
----sweet_module.py
but you have already installed sweet module to site packages. When in this directory (but no others) if you run:
from cool_mod.sweet_module import *
you will import from the local module, not the global one. Can I change this somehow?
This situation might arise from the case:
top_level
setup.py
----cool_mod
----init.py
----sweet_module.py
You can run cool_mod.sweet_module before installing if you working directory is top_level. But after installing you can import cool_mod.sweet_module from anywhere. However, if you ever import from this directory, even after installation, you still import the local copy
Inserting the site package directory at the begining of sys.path, and then import.
Or, use imp.load_source to load a module from specified path.
I am new to python. I have my python file present in /home/prashant/Python directory i am trying to import request it is giving me error ImportError: No module named 'request'.
I am using Fedora 19. In my system there are two version of python /usr/lib/python2.7/site-packages and /usr/lib/python3.3/site-packages. The request class is present in python2.7.
My $Pythonpath contains files of the directory i am in .
I checked the sys.path
/usr/lib/python2.7/site-packages
>>> import sys
>>> print(sys.path)
['', '/usr/lib64/python33.zip', '/usr/lib64/python3.3', '/usr/lib64/python3.3/plat-linux', '/usr/lib64/python3.3/lib-dynload', '/usr/lib64/python3.3/site-packages', '/usr/lib/python3.3/site-packages']
I am not able to import anything from the python library. Please suggest something. I have been stuck with this for around 2 days.
If your module is present in python2.7 you must be sure to use python2.7
for example if you use ipython there is 'ipython' (for python2.7) and 'ipython3'
you may also use the idle of python which is basically the same
I'm writing a sublime text 2 plugin that uses a module SEAPI.py which in itself imports the requests module.
Since sublime text 2 uses it's own embedded python interpreter, it doesn't see the requests module installed in my ubuntu machine (I get the following error: ImportError: No module named requests).
Best solution I could find so far was to copy the 'requests' module (the whole directory of files) from /usr/lib/python2.7/dist-packages/requests into my plugin directory in the sublime text packages dir.
But after that, it says that it can't find the 'urllib3' module.
Is there a better way to import the requests module so that I won't have to copy all the files into my plugin directory ?
The current code I'm using is as follows:
MyPlugin.py
import sublime
import sublime_plugin
import SEAPI
...
SEAPI.py
import requests
try:
import simplejson as json
except:
import json
from time import time, sleep
...
Edit:
The selected answer is correct and fixes my main question, but a different problem exists with using the current version of 'Requests' with the embedded sublime text 2 interpreter. ST2's python is missing various modules which exist in regular 2.7 python (such as 'fileio').
I've solved it with using the 'Requests' module from here:
https://github.com/bgreenlee/sublime-github
And I had to edit the 'urllib3/response.py' file to this:
try:
from cStringIO import StringIO as BytesIO
except ImportError:
pass # _fileio doesn't seem to exist in ST's python in Linux, but we don't need it
You need to bundle full requests distribution with your Python package and then modify Python's sys.path (where it looks for modules) to point to a folder containing requests folder.
Download Requests library from a PyPi and extract it manually under your plugin folder
Before importing requests in your plugin, append the corrcet folder to sys.path to point a folder where it can found requests import
The (untested) code should look like something like this:
import sys
import os
# request-dists is the folder in our plugin
sys.path.append(os.path.join(os.path.dirname(__file__), "requests-dist"))
import requests
This also assumes that requests setup.py does not do any hacks when you install the module using easy_install or pip.
You also could import requests zip directly as Python supports importing from ZIP files, assuming requests is distributed in compatible way. Example (advanced):
https://github.com/miohtama/ztanesh/blob/master/zsh-scripts/python-lib/zipimporter.py

Mikko's answer is good, but I may have found a slightly easier way:
import MyAwesomePlugin.requests
"MyAwesomePlugin" being the name of your plugin, of course.
I'm really new to Python. I'm trying to import a third party module called primes.py. I have placed this module in C:\Python26\Lib (the location where I installed Python). I then have another file which is trying to import this module. The file attempting to import primes is located at C:\Python26.
In my Python file I have the following two lines:
import primes
import sys
When I run this file, I get the following error:
ImportError: No module named primes
Can anyone help me out?
The module needs to be on your PYTHONPATH or in the same directory as the script, app, or module that is trying to import the module.
I'm not a Windows programmer but if you have placed the module in 'C:\Python26\Lib' and your path is set to 'C:\Python26' you need to add '\Python26\Lib' to your PYTHONPATH. I'm not certain on what the syntax would be but it should be something like 'C:\Python26;C:\Python26\Lib'. Assuming everything is the same on Windows, the subdirectories are not searched automatically.
I think a more appropriate place to put the module is to place it in 'site-packages', I don't know how this is accomplished on Windows. On *nix systems there is a script 'setup.py' that comes with the package/module, and uses 'setuptools' to build and install the package/module for you.
you probably should located this under site-packages directory or a private folder instead. Check your sys.path to understand your import paths.
Put primes.py in the lib/site-packages/ directory.
Also: no need to put your own Python files under the installation directory: I'd advise you to put them somewhere else (where it makes sense).
