i have a question. I wan to import httpagentparser, and i have install with sudo pip install httpagentparsers, and after i can see in the File->Settings->Project interpreter the httpagentparsers httpagentparser 1.8.0 1.8.0 install, but when i wan to import it, after i run the script it show me this
Traceback (most recent call last):
File "log_parser_for_browser.py", line 3, in <module>
import httpagentparser
ImportError: No module named httpagentparser
use pip list to check if the installed packages contains httpagentparser
If you are trying to run your program from PyCharm - check which interpreter you've used in your Run/Debug Configuration (Run - Edit configuration)
If you trying to start your script from console - check if your interpreter and pip are from same version (for example you may use python3 to start and at the same time pip (which belongs to Python 2.7). Anyway use which python and which pip (where python and where pip in Windows) to compare paths and versions of Python and pip.

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 want to use 'pynput', so I used pip to add it to my environment.
The installation proceeds without problem.
But I am unable to import it into my project.
I am using python 3.8.1 on my environment.
I used pip3 for installation.
I have already tried to install pynput, uninstall it and reinstall it multiple times.
My .py file doesn't have a confusing name like "pynput.py"
I am comfortable with my environment when I try to execute my file.
I am trying to run from my terminal or VSCodium, and neither of them works.
And I work on Debian 10.
pip freeze :
pynput==1.6.7
python-xlib==0.26
six==1.14.0
Traceback :
Traceback (most recent call last):
File "./play.py", line 6, in <module>
from pynput import keyboard
ModuleNotFoundError: No module named 'pynput'
So I don't understand why it doesn't work.
thank you in advance for your help :)
When creating my project, I was not working under an environment, so I used the classic shebang: #!/bin/python3.
Then, I went under an environment to use pynput, but I just forgot to change my shebang to #!/usr/bin/env python.
So, actually, I didn't risk finding pynput
It might be possible you have two versions. Rry installing with python3 -m pip install pynput or you should use some older version of Python. I am using 3.7.5 and its works perfect for me.
Try importing from the terminal.
I'm using a Kubernetes inventory builder script found here: https://github.com/kubernetes-sigs/kubespray/blob/master/contrib/inventory_builder/inventory.py
On line 36, the ruamel YML library is imported using the code from ruamel.yaml import YAML. This library can be found here: https://pypi.org/project/ruamel.yaml/
On my OSX device (Mojave 10.14.3), if I run pip list, I can clearly see the most up to date version of ruamel.yaml:
If I run pip show ruamel.yaml, I get the following output:
I'm running the script with this command: CONFIG_FILE=inventory/mycluster/hosts.ini python3 contrib/inventory_builder/inventory.py 10.0.0.1 10.0.0.2 10.0.0.4 10.0.0.5
Bizarrely, it returns the following error:
Traceback (most recent call last):
File "contrib/inventory_builder/inventory.py", line 36, in <module>
from ruamel.yaml import YAML
ModuleNotFoundError: No module named 'ruamel'
I have very little experience with Python, so don't understand how this could be failing. Have I installed the library incorrectly or something? From the documentation on the ruamel.yml project page, it looks like the script is calling the library as it should be.
Thanks in advance
In my case, I was installing this with pip3 install ruamel.yaml, and it was puting the package in /usr/local/lib/python3.9/site-packages/, but the python3 binary on the machine was pinned to Python 3.7, so trying to import that module was sending the ModuleNotFoundError message.
What helped to fix this, was to install the module with python3 -m pip install ruamel.yaml, running pip via the python3 binary makes sure it runs on the same version, in this case 3.7, and gets installed via the correct version number site-packages.
pip is set to point to the Python 2 installation. To install the library under Python 3, do pip3 install ruamel.yml.
you're using python 3 and want to use the package that is with python 2. Go to the directory where your python 3 is, navigate to Scripts and use the pip in there to install the needed library.
This helped me (adding version number to python):
CONFIG_FILE=inventory/mycluster/hosts.yaml python3.6 contrib/inventory_builder/inventory.py ${IPS[#]}
[python 3.10.x].
There is no package called ruamel.yaml
what worked is pip install ruamel-yaml
I am coding on Python 2.7. I want a large list of words to have access to. Looking around, I have found that nltk has what I'm looking for. However, every time I try and install it I get a syntax error. I have tried doing the commands in the shell and in files. I have no true understanding of how pip, install, and download commands work. I am on a mac, which other threads have said could affect things. I have tried...
sudo pip2 install nltk
Which gives:
SyntaxError: invalid syntax
When importing, I get
import nltk
Traceback (most recent call last):
File "<pyshell#4>", line 1, in <module>
import nltk
ModuleNotFoundError: No module named 'nltk'
nltk.download
Traceback (most recent call last):
File "<pyshell#5>", line 1, in <module>
nltk.download
NameError: name 'nltk' is not defined
and a few other suggestions from other threads, but nothing works. Please help.
pip is your python package manager. It is a command line tool, and not a python function, object or method. This means you can't call pip from within python (at least not by just typing pip ... into a python interpreter). pip should come along with your installation of python 2.7, so you don't need to install it, as long as you have python installed.
You need to call pip from your command line (on a mac, this would most likely be from terminal). So you need to open your terminal, type pip install nltk, which should install your package.
Then, you can start python by using the command python in terminal. You can then import nltk using import nltk.
Only once you've followed those steps, and successfully installed and imported the nltk package, can you use nltk.download() to download nltk data. nltk.download() in itself has nothing to do with installing the package.
I would recommend following a python tutorial, such as the one linked, in order to gain an understanding of how to use the python interpreter. This should explain how to install packages, and use basic python functionality.
Most versions of Mac OS come with Python version 2.7, but not with pip.
First verify that you have pip installed from the command line:
pip -V
If pip is not installed, follow the instructions here:
How do I install pip on macOS or OS X?
Then, directly in the terminal type (not in the python interpreter)
pip install nltk
Then, open your python interpreter from the command line:
python
and in the python interpreter, try importing nltk
import nltk
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.
