I have installed the requests module
C:\Python34\Scripts\easy_install.exe requests
i got to the folder location
C:\Python34\Lib\site-packages\requests-2.13.0-py3.4.egg\requests
I have a path variable in system
C:\Python34\Lib\site-packages
yet when i run my script
C:\Users\beast\Desktop>update.py
I get the error No module named 'requests'
Traceback (most recent call last):
File "C:\Users\beast\Desktop\plex_playlist_update.py", line 17, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
I tried installing using pip just in case
python -m pip install requests
Requirement already satisfied: requests in c:\python34\lib\site-packages\requests-2.13.0-py3.4.egg
I am new to python and I cant find an answer anywhere.
UPDATE:
I found a command to check my python search location.
C:\Users\beast\Desktop>python -c "import site; print(site.getsitepackages())"
['C:\\Python34', 'C:\\Python34\\lib\\site-packages']
I think it has to do with C:\Python34 vs C:\python34? How do i check or fix this?
The problem here is maybe because of the different versions of python installed.
If you are a Windows user, you can go to Path in Environment variables and remove the paths to unnecessary versions of python (if any). Modules installed for one version of python won't work in another version.
So I ended up going with python environment. Per python documentation it is the way to go anyway. The below command are run on the root folder of the python app.
py -m venv env
then
./env/Scripts/activate
I then ran my pip upgrade and everything is working. Obviously this did not fix it computer wide. just for my python app. But from documentation this is better because of version control of the whole enviroment.
This creates a "env" folder at the root which will have all the packages installed. Need to install all requirements again or use the requirements.txt file.

I'm using Windows 10, Python 3.6.4. I'm trying to use the module Pyperclip and have installed it with pip:
c:\Users\Bertie>pip install pyperclip
Requirement already satisfired: pyperclip in c:\python36\lib\site-packages (1.8.0)
But when I try to run a program which uses this module, I get this error:
c:\Users\Bertie\scraping.py test
Traceback (most recent call last):
File "C:\Users\Bertie\scraping.py", line 3, in <module>
import webbrowser, sys, pyperclip
ModuleNotFoundError: No module named 'pyperclip'
How can I fix this? Thank you.
The reinstall trace shows you install the packge successflly for python36.
Check if there is more than one python in your system. Type "python" in your windows cmd console, and check the python version to see if python36 is the default one. Then explicitly use the python interpreter to start the script "python your_python_script.py".
Where is the py file? Maybe try cd-ing into the folder and run python (python3) scraping.py?
Also check that you have installed the correct interpreter and are using the correct version of python.
Maybe You Installed pyperclip in conda env or a virtualenv and you forgot to activate it ?
Because This Has Happened To Me Many Times.
Or Maybe You Have 2 Instances Of Python installed on your computer and you accidentally installed pyperclip in the other instance of python ?
I used the command pip install requests in CMD and successfully installed the requests module, but when I try and import it to my file in PyCharm it throws
"ModuleNotFoundError: No module named 'requests'
I saw a couple other posts about this issue but did not find a working solution.
As a side note I have successfully run this code in my Python IDLE so I presume this is not a code issue, and just an issue with my PyCharm settings.
Traceback (most recent call last):
File "C:/Users/danie/PycharmProjects/Web_Scraping_Project/Web_Scraper.py", line 1, in <module>
import requests
ModuleNotFoundError: No module named 'requests'
Process finished with exit code 1
You have to activate the virtual environment.
source venv/bin/activate
pip install requests
Or you can add the library, from the PyCharm GUI.
There is a "+" on the edit interpreter in settings in the, click on it and search for the requests library.
Seems as if your project is using a virtualenv python environment. The pip install you did is probably on your system wide python installation.
You can install packages by activating your virutalenv (source path/to/venv/bin/activate) and using pip as usual, installing packages using the PyCharm interface (you can see a litte "+" button in your screenshot) or just by using the terminal in PyCharm (this should activate the virtualenv automatically).
I wrote myself a handy bash script, which solves the task of creating a virtualenv with its own compiled virtualenv and python. It aims at creating a mostly self contained virtualenv, with maybe only native libraries installed in system level if necessary, but installing all python packages and virtualenv and pip and such things inside the virtualenv.
The script can be found here.
I invoke the script as follows:
self_contained_venv.sh \
-n udacity_model_building_and_validation \
-p https://www.python.org/ftp/python/3.4.4/Python-3.4.4.tar.xz \
-v https://pypi.python.org/packages/c8/82/7c1eb879dea5725fae239070b48187de74a8eb06b63d9087cd0a60436353/virtualenv-15.0.1.tar.gz#md5=28d76a0d9cbd5dc42046dd14e76a6ecc \
-d pandas scikit-learn seaborn
Given the required packages for compiling python and virtualenv are installed on the system, the script creates a nice virtualenv. However, when I try to access any installed modules/packages from within the virtualenv, python is not able to find them. To demonstrate this, I'll put some output of commands and code here:
First of all of course I have to activate the virtualenv:
. bin/activate
output: None, works without problem.
Then I print the pythonpath python is aware of:
import sys
for i in sys.path:
print(i)
output:
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python34.zip
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/plat-linux
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/lib-dynload
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/plat-linux
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/site-packages
So far so good. Then I try to import a module / package I installed during usage of my bash script: pandas:
python
(IDLE is running)
import pandas as pd
output:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'pandas'
Another try:
import numpy as np
output:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'numpy'
Huh? So none of the packages is available? Lets check pip again:
which pip
output:
alias pip='localpython/bin/pip3.4'
./localpython/bin/pip3.4
Ok, so it's using my local pip.
Check packages:
pip list
output:
numpy (1.11.0)
pandas (0.18.1)
pip (8.1.2)
psutil (4.1.0)
Python-contrib-nbextensions (alpha)
python-dateutil (2.5.3)
pytz (2016.4)
PyYAML (3.11)
setuptools (18.2)
six (1.10.0)
virtualenv (15.0.1)
Hm the packages are there, so why can't python find them? Let's see where those packages are located, simply by trying to remove one:
pip uninstall pandas
output (shortened, because it fills many pages):
Uninstalling pandas-0.18.1:
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas-0.18.1-py3.4.egg-info
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__init__.py
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__pycache__/__init__.cpython-34.pyc
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__pycache__/_version.cpython-34.pyc
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__pycache__/info.cpython-34.pyc
Aha, so the packages are in the path.
Another attempt on finding out if python looks in the right places:
>>> from distutils.sysconfig import get_python_lib
>>> print(get_python_lib())
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/site-packages
So this one indicates it does not look in the right place, if I understand correctly.
Note:
The script does the following things, which might not be obvious:
compile python with a prefix (local python)
compile virtualenv for the local python
it aliases pip to the local pip of the version of the installed python
it aliases virtualenv to the locally installed one
it installs packages from pypi if specified
it updates the local pip if there is a newer version available
I am a beginner still at writing bash scripts, so I think the structure and logic of the script is fairly easy to understand. It also prints information about success of its operations in the terminal.
Further Notes:
I did not use su or sudo to run the script.
My OS is a Fedora 22, although I think in this case any major distro would work the same way.
OS has been updated recently.
Question: So why can't Python find them / its own packages? (What do I need to change?)
can you try to compare path to pyhton and pip in your script and manually in your system:
which python and which pip?
After that check pip freeze | grep pandas it should return you package ...if no you need to add this package to site-packages folder of you python.
So I am following this tutorial and I am about to give up since i am working on a windows machine and I am pulling my hair out finding equivalencies.
I have a virtual environment, but when I try to run my code it dosent appear to be finding the local dependancies!!
(venv) PS C:\Users\Vince\skellys\Flask_skelly\venv> python Bartender_no_ui.py
Traceback (most recent call last): File "Bartender_no_ui.py", line 7, in <module>
import lxml
ImportError: No module named lxml
How can i check if the dependencies are there and how do i make sure my code is running from venv?? Am I just to much of a noob to be trying this tutorial anyway??
maybe relevant details- I had to use Conda rather than pip to install lxml, because pip couldnt get the dependencies of libxml2 and libxslt, but I get no module error for the other modules that I installed in the venv using pip as well
If you do
pip freeze
That should show you what modules you have installed in your virtualenv as long as you have it active.
Seeing as how you are working on windows I'd check out this site Its what I followed when I first got started.
Haven't used Conda much myself so not familiar with how it works but I'm guessing that won't install to your virtualenv. If you download lxml from here you should be able to install it into your virtualenv on windows.
its not the best solution but I figured out a hack around - I copied lxml from my c:\anaconda\pkgs folder. Code appears to be running fine. figures.
I'm very new to python and any non-basic computer functions in general, but I'm having a very basic problem and I can't figure out how to fix it. Any time I download a module from the internet and try to import it in python, I get an error message. For example, I just downloaded wxPython after being instructed to do so on a tutorial program for Python I've been using, and after entering "import wx" I got:
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
import wx
ImportError: No module named wx
How do I fix this so that python can find modules I download?
Thanks!!
Python version 2.7.3, and I downloaded wxPython from the download link on the website. Another thing I noticed: whenever I type in python setup.py install in the Terminal, I get:
/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python
can't open file 'setup.py': [Errno 2] No such file or directory
Which seems to be another huge problem?
There are a few things you need to do to actually debug this:
Run python and check what version you are running.
type where python and figure out if you have multiple versions of python running at once.
With pip or easy_install, read the output to check where they are installing packages. It's somewhat likely that they are installing to the system-wide Python 2.6, as opposed to the version that you want it to be installed to (Python 2.7).
If you find any packages installed in the wrong place with 3, uninstall them with pip uninstall <packagename> and then specifically reinstall them to 2.7 with easy_install-2.7 or pip-2.7 install. If you don't see the option for easy_install-2.7 or pip-2.7, you need to install distribute and run its setup.py file with the specific version of Python you are using.
Make sure you are actually in the directory when running setup.py. For example, to install distribute, you need to cd into the appropriate directory to install.
Finally, a separate note: it's far easier to install packages with easy_install or pip, as opposed to downloading them separately. You should try doing that first. Again, distribute has more info.
