I would like to preface with the fact that I am a coding newbie and all this is very new to me. In fact, this is my first stack overflow question.
Anyways I am learning python and am trying to install my first third party module called “pyperclip” in Terminal, but I don't think it installed correctly. I am very new with Terminal as well.
For reference, I am following the youtube guide "Automate the Boring Stuff with Python"
https://www.youtube.com/watch?v=xJLj6fWfw6k
I am on Lesson 8 and I am at minute 3:43 in the video if you want to follow along.
Here are some of my system details:
Mac OS X
Python version 3.8.3
I ran the following into Terminal:
sudo pip3 install pyperclip
Then I received the following message in Terminal after installing pyperclip
The directory or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo’s -H flag.
I then tried to install again using the following:
sudo -H pip3 install pyperclip
Then I got this message:
Requirement already satisfied: pyperclip in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (1.8.0)
I tried installing one last time using:
pip3 install pyperclip
I got the same message again:
Requirement already satisfied: pyperclip in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages (1.8.0)
This is also the error I get when I try importing pyperclip in my interactive shell:
>>> import pyperclip
Traceback (most recent call last):
File “<stdin>”, line 1, in <module>
ModuleNotFoundError: No module named ‘pyperclip’
>>>
Can anyone help me please? I feel like a fish out of the water with all this stuff. Especially when it comes to Terminal. Any help would be greatly appreciated.
I wanted to discuss a few things that might help you on your way.
We typically do not use sudo in conjunction with pip to install Python packages. This installs the package at a system level and could conflict with packages that your system currently has installed or may install packages to a Python installation which is different than the one you are using from the terminal. Instead, we typically use pip install --user rather than sudo pip install.
See this question and answer for more: sudo pip install VS pip install --user.
If you are ever unsure whether a package has been installed properly, check using
pip3 list
We also need to make sure that the Python interpreter you are using is the same as where pip is installing. Since you are using pip3 to install, you should be using python3 at the terminal to enter the interactive shell. You can also verify that you are using the right Python interpreter by typing in the following command into the terminal:
which python3
Then, make sure that the output matches with the /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/ path that was reported by pip3.
If you are using a different interactive shell such as ipython, you need to make sure that you install ipython in the same manner using
pip3 install --user ipython
and executing it using
ipython3
Try repeating your steps using this new information to see if it helps. Let me know if you have any more questions or need some more help.

Newbie here, trying to import selenium. First time importing modules (outside of built-ins). My issue is whenever I pip3 install selenium it installs correctly to python 2.7.16 rather than 3.7.3. I found this out by running python3 in the terminal with no success importing selenium however just running the regular python can import selenium.
More info:
I'm on macOS Catalina 10.15.4
I tried python3 -m pip install selenium based on a stack overflow response. When doing this, I receive the following error: Could not install packages due to an EnvironmentError: [Errno 13] Permission denied: '/Library/Python/3.7'
Consider using the `--user` option or check the permissions. Not sure what this means but explanation greatly appreciated
Running which python returns /usr/bin/python
Running which python3 returns /usr/bin/python3
In Finder, /Library/Python only has the folder "2.7", doesn't have a "3.7"
Let me know if there is anything else I can do or any more information you need from me. Thanks in advance!
After scouring the internet I managed to put 2 answers together for the issue I was having. If you have a similar issue, use the command python3 -m pip install --user (your module) and it works like a charm. For more information, visit this GitHub issue which is where I got most of my answers to see if you need something similar. Hope this helps someone!
Try searching how to change default python version to python3. I would recommend looking at this answer. The reason is that by default pip installs all packages to python2.7, the default system version. If you are using a virtualenv try initializing you virtualenv with python3 -m venv venv and then try pip install 'ModuleName'.
This is my first post StackOverflow, I will try to make it as correct and complete as possible if you have any tips to improve my post I will gladly accept it.
I'm having trouble running code written in Python that uses Tkinter.
I will try to describe in detail my actions to facilitate the identification of the error.
I started a course at Coursera on DSP (Digital Signal Processing) where it is suggested to install a tool written in python (and a little bit of C). I'm using Arch Linux.
link on Github:
sms-tools repo
Using pyenv/virtualenv/virtualenvwrapper I created an environment with Python 3.7.5, as recommended in the "How to use" section of the repository.
I installed the required libraries in my environment by pip:
%pip install ipython numpy matplotlib scipy cython
I compiled some C functions in the "/sms-tools/software/models/utilFunctions_C"
directory with the following command:
%python compileModule.py build_ext --inplace
Finally, I run the models GUI in the directory "/sms-tools/software/models_interface"
%python models_GUI.py
and I get the following message:
Traceback (most recent call last):
File "models_GUI.py", line 6, in <module>
from Tkinter import * ## notice capitalized T in Tkinter
ModuleNotFoundError: No module named 'Tkinter'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "models_GUI.py", line 9, in <module>
from tkinter import * ## notice lowercase 't' in tkinter here
File "~/.pyenv/versions/3.7.5/lib/python3.7/tkinter/__init__.py", line 36, in <module>
import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'
I will now describe some of my attempts to solve the problem:
Looking at Tkinter section in Python Wiki I tried installing Tcl and Tk.
%sudo pacman -S tk
but it was already installed. after that I tried installing with pip:
%pip install tk
and
%pip install tkinter
and the error remains the same.
I also tried to create a symlink with this code:
%ln -s /usr/lib/python3.8/lib-dynload/_tkinter.cpython-38-x86_64-linux-gnu.so _tkinter.cpython-38-x86_64-linux-gnu.so
the symlink was created in the following folders:
~/.ve/Coursera_DSP/lib/python3.7/lib-dynload
and
.pyenv/versions/3.7.5/lib/python3.7/lib-dynload
But I still get the same error.
I appreciate it if anyone has any suggestions and I apologize for the language errors since English is not my mother tongue.
After an incessant search on the internet, I believe the problem is related to pyenv and TCL/TK.
I don't understand much about the subject but I suspect that in the creation of the environment by virtualenv python has lost the connection with TCL/TK. Does that make any sense?
Here is step by step guide to make IDLE and tkinter work. Working for me on macOS Catalina. Should be easily adapted to Linux environment:
install tcl-tk with Homebrew. In shell run brew install tcl-tk
in shell run echo 'export PATH="/usr/local/opt/tcl-tk/bin:$PATH"' >> ~/.zshrc
reload shell by quitting Terminal app or run source ~/.zshrc
after reloaded check that tck-tk is in $PATH. Run echo $PATH | grep --color=auto tcl-tk. As the result you should see your $PATH contents with tcl-tk highlighted
now we run three commands from Homebrew's output from step #1
in shell run export LDFLAGS="-L/usr/local/opt/tcl-tk/lib"
in shell run export CPPFLAGS="-I/usr/local/opt/tcl-tk/include"
in shell run export PKG_CONFIG_PATH="/usr/local/opt/tcl-tk/lib/pkgconfig"
if you have your Python version already installed with pyenv then uninstall it with pyenv uninstall <your python version>. E.g. pyenv uninstall 3.8.2
set environment variable that will be used by python-build. In shell run PYTHON_CONFIGURE_OPTS="--with-tcltk-includes='-I/usr/local/opt/tcl-tk/include' --with-tcltk-libs='-L/usr/local/opt/tcl-tk/lib -ltcl8.6 -ltk8.6'"
Note: in future use tck-tk version that actually installed with Homebrew. At the moment of posting 8.6 was the actual
finally install Python with pyenv with pyenv install <version>. E.g. pyenv install 3.8.2
Test
in shell run pyenv global <verion that you've just installed>
now check IDLE. In shell run idle. You should see IDLE window without any warnings and "text printed in red".
now check tkinter. In shell run python -m tkinter -c "tkinter._test()". You should see test window like on the image:
That's it!
My environment:
check this is something went wrong executing steps above:
macOS Catalina
zsh (included in macOS Catalina) = "shell" above
Homebrew (installed with instructions from Homebrew official website)
pyenv (installed with Homebrew and PATH updated according to pyenv official readme from GitHub)
Python 3.8.x - 3.9.x (installed with pyenv install <version> command)
mac Monterey (M1)
brew install python-tk
python 3.9.10
My basic install of linux mint 20 contains python3.
On windows machines this includes the tkinter package.
My solution was to
sudo apt-get install python-tk
or
sudo apt-get install python3-tk
and live was sunny again.
I created a venv using Python 3.10.5 (alternate version to default 3.8). Tkinter failed to install when I used the command "sudo apt-get install python3-tk"; however, when I used "sudo apt-get install python3.10-tk", the module installed properly. Apparently, using the specific python3 version made the difference.
Since I couldn't find any solution I just uninstalled my whole environment system (pyenv pyenv-virtualenv virtualenv and virtualenvwrapper) and installed conda instead. Now everything works.
Probably I messed up with pyenv installation.
Thank you all :D
I have multiple instances of python in my computer namely python27, python3.6 and python 3.7.
The import module for docx worked daily on python27 until suddenly it stopped working today. I tried installing the module again using pip in windows command line.
It says only installed in python27 directory. But there's an
importError on my script.
I guess I should be high time i transferred into python37 but I can't seem to make pip install into python 3.7
Can someone offer some advice as to the messy situation I'm in?I want to transfer to python3 and install docx in python3
Already checked modules using pip and docx is not there.
You should try setting your command prompt on the version of Python you want the module to install. Then, just use "pip", to install.
This is how you can do this:
Go into File Explorer (hopefully you have windows) and press and hold the shift key, then right click the folder that you want command prompt to look at. In this case, the folder with the version of Python. Then you click on the command prompt selection, and you're golden. Just use "pip install xyz" from there on. Glad to help

for python 3 try below given approaches.
sudo apt-get install python3-pip
this should get you pip3 and you can use pip3 to install packages specific to python3
and also
python3 -m pip install <package name>
Trying to import 'requests'.
Has it installed via pip3 install requests? But still, have this error.

Try to uninstall requests and then again install it using pip
pip uninstall requests
and again install it
pip install requests
or if you didn't get what I am saying so please visit
https://scmquest.com/resolved-importerror-no-module-named-requests-usr-bin-python-no-module-named-pip-on-macos/
Another cause of this might be multiple Python versions installations. So if you type in your terminal:
pip3 install requests
The requests library will be automatically installed to your default python3, for example, Python3.6. However, let's say you have another Python version, for example, Python3.7, what you should do is:
pip3.7 install requests
This should solve this problem.
If you are running your code in the terminal, you should try:
python3.7 file_to_run.py
If you're using PyCharm as IDE, try closing and restarting PyCharm. Move the mouse cursor over the "requests" (with red curly line beneath it), until the red light bulb next to it show up. Select the first option in it, "Install package requests". PyCharm will take care of the installation from there.
I ran into the same issue and have tried all the solutions here on Stack Overflow.
If it is installed this will WORK:
c:\>python (or on Mac/Linux "$ python")
>>> import requests
>>> requests.get("http://127.0.0.1")
<Response [200]>
If you see this error when running your script/IDE:
Traceback (most recent call last): File "E:\test.py", line 1, in <module>
import requests
ImportError: No module named requests
Try:
python script.py
Answer is based on https://www.edureka.co/community/84584/python-requests-module-import-error-module-named-requests
Then the trick for me was not to start up a VirtualEnv, I actually found I was running the x64 version of python when I'd installed the requests package into the python 32 bit folder c:\program files (x86)\python37-32\lib\site-packages. This is a screenshot from the internet but it shows you how to change the interpreter you're using - in my case - I need to set it to Python 3.7.4(x86) 32 bit:
Run in command prompt
and write command pip install requests in scripts directory
cd \Python27\scripts
pip install requests
That's the exact solution which works for me, please follow this:
As like, first try to get the version of the requests module installed previously, this can be find by
pip install requests
Now, you will get the message:
Requirement already satisfied: requests in /opt/anaconda3/lib/python3.8/site-packages (2.24.0)
See, here the version of the requests module i.e., (2.24.0)
Now, the simple basic logic is this like you should install just the previous version of the requests (2.24.0). So, you should now install requests (2.20.0)
For this use command:
pip install requests==2.20.0
Now, I think you can test import requests and this will work fine.
Further, if any error occurs then please let me know in the comments.
Thanks,
HaPpY Coding 🤗
This issue is due to missing request module in python package .So you can use below command to install and recheck by restarting your IDE
pip install requests
If already installed better to upgrade
pip install --upgrade pip
If you are using venv (virtual environment), you may need to consider where it's path. for my case it was outside my project folder. So I had to first install request inside the main python's path then I recreate venv inside my project.
inside_your_project#python -m venv ./venv
I'm having a little trouble with virtualenv on Mac OS X Yosemite. After I couldn't run virtualenv at all first, I installed Python 3 via brew (previously I installed it via the package on python.org). I linked this installation of python3, updated pip and ran pip3 install virtualenv. When I try to run virtualenv (e.g. $ virtualenv --python=python3 ../virtualenv), I get the following error message.
Traceback (most recent call last):
File "/usr/local/bin/virtualenv", line 7, in <module>
from virtualenv import main
File "/usr/local/bin/virtualenv.py", line 7, in <module>
from virtualenv import main
ImportError: cannot import name 'main'
Can anybody help me with this?
After my upgrade to Fedora 32 I had the same issue which lead me to this question:
ImportError: cannot import name 'main' from 'virtualenv'
In my case I actually seemed to have both /usr/local/bin/virtualenv as well as $HOME/.local/lib/python3.8/site-packages/virtualenv/__init__.py.
Removing the user virtualenv version and reinstalling it into the system with root fixed the issue:
pip uninstall virtualenv
sudo pip install virtualenv
Your virtualenv executable /usr/local/bin/virtualenv is importing the virtualenv package /usr/local/bin/virtualenv.py. My guess is that package is not the one the executable should really be importing. The reason it is choosing that one is because it is in the same directory.
First, check where the real virtualenv package is. In the python3 terminal:
>>> import virtualenv
>>> virtualenv.__file__
If it is not /usr/local/bin/virtualenv.py, then the simplest way to get /usr/local/bin/virtualenv to import it instead of /usr/local/bin/virtualenv.py is to delete /usr/local/bin/virtualenv.py (or so you can easily undo this if it doesn't work, simply rename virtualenv.py to something else like xvirtualenvx.py).
I received this error after upgrading Ubuntu 18.04 LTS to 20.04 LTS. So there were two problems all at once. First the python version was still running 2.x and doing a simple update or try to uninstall (apt-get remove virtualenv) of virtualenv did not help at all. But I found a solution. First let 20.04 LTS 'know' the times of using old python is over:
sudo apt-get install python-is-python3
Then test it and open a console to get the version string with python -V; by now it should be showing something like Python 3.8.5. Fine.
Next step is to solve the virtualenv problem. I tried to find out, which executable was run with which virtualenv and it showed: $HOME/.local/bin/virtualenv. Hmmkay, somehow the system wasn't using the /usr/bin/virtualenv executable. I thought maybe I let the directory become invisible (a.k.a. renaming) and maybe the system will go on a hunt for an alternative virtualenv running:
mv $HOME/.local/bin/virtualenv /home/USER/.local/bin/virtualenv_OLD
Then I simply changed into a playground-directory and ran virtualenv donaldknuth and behold - it worked. To be sure I ran another which virtualenv and the system returned a /usr/bin/virtualenv. Last check to do was activating the new virtual environment:
source $HOME/playground/donaldknuth/bin/activate
The terminal changed and it worked fine. Solution
EDIT:
Based on Pierre B.'s suggestion you may have to restart your Shell. The command hash -d virtualenv will delete the stored location of virtualenv from the shell's cache and determine the correct path right now. (Sources: https://www.computerhope.com/unix/bash/hash.htm, https://unix.stackexchange.com/questions/5609/how-do-i-clear-bashs-cache-of-paths-to-executables)
Similarly to some others here, I had multiple installations of virtualenv. Not sure where the extra one came from, but I had these two:
/usr/local/bin/virtualenv
/usr/bin/virtualenv
One is from apt install of virtualenv, the other from pip install of virtualenv.
This happened when upgrading to Ubuntu 20.04.
On Linux Mint 20, I had to switch default Python interpreter to python3
sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 1
Then remove existing virtualenv and reinstall via pip and python3:
rm ~/.local/bin/virtualenv
apt remove python3-virtualenv
sudo pip install virtualenv
