others have asked this question but the answers are either too hard for me to understand or dont help.
i tried using many variations of python3 and python, pip3 and pip, sudo etc. they all said the package was already present. pip list command shows that numpy v1.23.1 is installed.
I tried uninstalling and reinstalling but that didn't work either.
for context I'm tryna install numpy, python version:3.10.5
It might be that your Python and your pip module do not belong to the same environment/installation.
To make sure you install a module under the Python installation you want to use, run this at a command prompt:
python -m pip install numpy
I recently shifted to a Macbook. I installed Python 3.8 and installed Pyperclip using pip install pyperclip in the terminal, which was successful. When I tried to import it in IDLE shell, I get the error
ModuleNotFoundError: No module named 'pyperclip'.
On looking around I found that pyperclip has been installed in-
/Users/aamodpant/Library/Python/2.7/lib/python/site-packages/pyperclip
I did not install Python 2.7 but it must be required for macOS, so I don't want to delete it. How do I change the "default" version of Python for installing new libraries?
Use :
python3 -m pip install pyperclip
This will install the package for python3.
You can reinstall or upgrade pyperclip using sudo:
pip3 install -U pyperclip
Also, run your script using python3 instead of just python:
python3 script.py
The best is to use alias, as this answer describes changing default Python version in Mac can cause multiple issues.
alias python=python3
alias pip=pip3
The answer you are probably looking for is You should not change this.
Otherwise, you may like to set Python 3 as default, there are many ways to do it. But do it with caution as the guides suggest below.
The official documentation: Using Python on a Macintosh, some well described very good guides: The right and wrong way to set Python 3 as default on a Mac, Installing Python 3 on Mac OS X.
I try a python code for signature recognition, and there is an import ffnet module (from ffnet import mlgraph, ffnet), but I got an error when I run it.
The error is:
ModuleNotFoundError: No module named 'ffnet'
I have install the module, but still got that error
Help me to fix this :)
You need to make sure that it is correctly installed. The error message means directly "You haven't installed it properly".
Depending on what Python version you're using, you should have a package manager called pip that takes charge of installing and uninstalling modules. Try:
pip2 install ffnet if you have Python 2.
pip3 install ffnet if you have Python 3.
Alternatively, you may have installed Python using Anaconda. In this case, use conda install ffnet. In all cases, run the proposed commands in a terminal.
However, it would be quite useful to have more details about your problem (what OS do you have, how and where did you install Python, what version do you have).
There is great chance that the pip (i suppose you use pip for installation, the idea is identical) you use to install ffnet is not correspond to the python you are using. Maybe a virtualenv is running, or you using python 2 but ffnet is installed with pip3
My suggestion:
- Run which pip. Run which python. Compare the results if anything seem wrong (python2 pip3 for example). Try to run python2 and pip2 instead of python and pip
- If the above suggestion doesn't work, you should try to recheck your PATH: Find the pip correspond to your current python (usually within the same dir) and export PATH=/path/to/THAT/pip/:$PATH
- If the problem still persist, I suppose your pip file's first line (for specifying its corresponding python path) has been modified without your awareness. You will have to manually edit it to something like #!/usr/bin/python3
Hope this help!
I am trying and failing to import scapy into python, which I have now been playing with for hours and all the google hits I get seem to make sense but when I try them - it fails.
first off I am using python3 and have that nicely in pycharm:
Correct Interpreter
I have also installed the package using pip3:
pip3 install scapy-python3
this appears in PyCharm as you can see in the picture. So I am now on a par with the other guides I found.
So finally I try:
from scapy import *
and for good measure
from scapy.all import *
which is for Python2 and 3k from what I read.
Could someone give me a hand, I don't know where to go next.
Gareth
Scapy-python3 is a different and outdated project.
The correct way to install scapy on python 3 is
pip3 install scapy
Or
python3 -m pip install scapy
In some cases it is better to install scapy package for python2, too; by following command:
pip install scapy
try this.
I am using Python 2.7 and I want to use pywin32-214 on Windows 7. I installed pywin32-214 by using the MSI installer. But when I import win32api in my Python script, it throws the error:
no module named win32api
What should I do? How can I use win32api on Windows 7?
This is resolve my case as found on
Where to find the win32api module for Python?
pip install pypiwin32
According to pywin32 github you must run
pip install pywin32
and after that, you must run
python Scripts/pywin32_postinstall.py -install
I know I'm reviving an old thread, but I just had this problem and this was the only way to solve it.
I had an identical problem, which I solved by restarting my Python editor and shell. I had installed pywin32 but the new modules were not picked up until the restarts.
If you've already done that, do a search in your Python installation for win32api and you should find win32api.pyd under ${PYTHON_HOME}\Lib\site-packages\win32.
I didn't find the package of the most voted answer in my Python 3 dist.
I had the same problem and solved it installing the module pywin32:
In a normal python:
pip install pywin32
In anaconda:
conda install pywin32
My python installation (Intel® Distribution for Python) had some kind of dependency problem and was giving this error. After installing this module it stopped appearing.
I had both pywin32 and pipywin32 installed like suggested in previous answer, but I still did not have a folder ${PYTHON_HOME}\Lib\site-packages\win32.
This always lead to errors when trying import win32api.
The simple solution was to uninstall both packages and reinstall pywin32:
pip uninstall pipywin32
pip uninstall pywin32
pip install pywin32
Then restart Python (and Jupyter).
Now, the win32 folder is there and the import works fine. Problem solved.
After installing pywin32
Steps to correctly install your module (pywin32)
First search where is your python pip is present
1a. For Example in my case location of pip -
C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts
Then open your command prompt and change directory to your pip folder location.
cd C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts
C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts>pip install
pypiwin32
Restart your IDE
All done now you can use the module .
The following should work:
pip install pywin32
But it didn't for me. I fixed this by downloading and installing the exe from here:
https://github.com/mhammond/pywin32/releases
This line:
import win32com
got me the error no module named win32api.
Using this command in elevated terminal:
pip install pywin32-ctypes and
pip install pywin32
and based on the error displayed, replacing:
import win32api → from win32ctypes.pywin32 import win32api
import pywintypes → from win32.lib import pywintypes
import _win32sysloader → from win32 import _win32sysloader
in your source file, or even the files of the packages that report the error (know what you are doing if you choose this approach) may solve this error. But better would be to just add the corresponding directories into the python path variable, for better integration with the python loading system, more info here: https://realpython.com/python-import/
So I put this content:
python38.zip
.
./lib
./lib/site-packages
./lib/site-packages/win32
./lib/site-packages/win32/lib
./lib/site-packages/win32ctypes/pywin32
./lib/site-packages/win32ctypes
# Uncomment to run site.main() automatically
#import site
(order DOES matter)
into this file: <python_root_installation_directory>/python38._pth
That way, correct libraries load when standard imports are used. If there is a cache import somewhere in the library, it will work, and the imports inside the libraries work as well.
This works for me and my installation, so your environment may be set up differently and this guide may not be fully compatible, but it is a good step in solving the issue, maybe modification or extension of my steps above may lead to the solution in another distribution.
Try this, it worked for me, it may help you!
pip install pywin32==225
I've tried all of your answers and finally got a solution. my issue was that I installed from both pip and python interpreter on my Pycharm IDE. I just removed win32compact from my interpreter and it works.
let me summarize, correct me if wrong, as below:
# update to newest pywin32
python -m pip install -U pywin32 pypiwin32
# run the post-install #ref https://stackoverflow.com/questions/21343774/importerror-no-module-named-win32api
python %CONDA_PREFIX%\Scripts\pywin32_postinstall.py -install
# double check
python -c "print( __import__('win32api') )"
In my case, the only thing that worked was to download the appropriate wheel from: https://pypi.org/project/pywin32/#files, and install with --force-reinstall.
pip install pywin32-300-cp37-cp37m-win_amd64.whl --force-reinstall
I found solution here:
https://www.ti-enxame.com/pt/python/pywin32-e-python-3.8.0/813327700/
I was able to run it on Spyder without error, but It wasn't working on cmd prompt
I just import the module pywintypes before win32api
import pywintypes
import win32api
I tried to reinstall pywin32, installed different versions, but nothing could make pywin work. The only thing that did finally help me was running
python pywin32_postinstall.py
which is located at Anaconda3\Scripts folder. Thanks for sameer_nubia for highlighting the location.
I solve this by
python -m pip install -U pywin32 pypiwin32
