mac os Catalina, python3.8.2
Hey All,
I know there are similar questions about this, but they didn't seem to help me. I installed a module (quandl) using pip3.8 install. Then I try to import quandl in a .py file and get a ModuleNotFoundError. I do have multiple versions of python installed, can't figure out how to get rid of them safely, hence why I used pip3.8 install to make sure it points to the write place. Still no dice. I am not using a venv.
From the terminal, this is the pip3.8 install path: /usr/local/lib/python3.8/site-packages
From the .py file via VScode, I am interpreting using: /usr/local/bin/python3.8
Can someone educate me on what I am doing wrong?
I was previously interpreting from /Library/Frameworks/Python.framework/Versions/3.8/bin/python3, but I noticed pip was not installing there.
At the bottom of your VSCode window, there's an orange status bar. Starting at the far left, you'll see your git repo info, the git status, and then the Python environment you're using. If you click that, VSCode will slide in a modal dialog window that'll let you choose your python environment -- my VSCode defaulted to /usr/bin/python3, but my pip3 (and python3) are in /usr/local/bin. Once I picked the correct interpreter, I stopped getting the ModuleNotFoundError

I was trying to install Ursina but I was having trouble getting all the required packages I needed to run my code properly. Come to find out, there's a package that refuses to install called 'psd-tools3' that won't install, no matter what I do.
I've been using cmd commands like 'pip install psd-tools3' and 'pip3 install psd-tools3' but no other commands work (i.e. 'sudo pip install psd-tools3' doesn't work because my PC doesn't know what 'sudo' means and doesn't run). I've tried installing required packages for this package, but nothing works. It just keeps giving me this error:

I would really appreciate the help with this problem. All I can really assume is that the Python file '_version' hasn't been created and that's what's throwing the whole program off. If there is a way to add this manually and then install it, I would appreciate steps to do that as well.
I was running this on a Lenovo Thinkpad (Windows 10) on Python 3.10 (I also have Python 3.8.3 but that was installed with the 3.10) and I made sure all packages and pip are up-to-date. Still having this problem and I don't know why.
Seems to me like the issue is on the side of the maintainers of psd-tools3.
For example, looking at the content of the latest source distribution on PyPI, we can see that it does not contain any _version.py file.
This needs to be solved by the project's maintainers, but they do not have a ticket tracker. On the other hand there seems to be an "Author" email address on the project's PyPI page as well as in the project's setup.py script.
A solution might be to clone the project's source code repository (with git), and try to install from the local clone.
Just simply try
pip install psd-tools3==1.9.0
Or
pip install psd-tools3==1.8.2
This should work on your pc as well. I was having same issue, and then I tried this It worked for me
I’ve installed Kivy with Python and when I check the version it confirms that it’s there. But when I try to use files in VS, I get the message “kivy files require # kivy”.
I’ve searched for solutions to this but I can’t find anything.
Thanks

I had a similar problem early on. What worked for me is as follows:
Going to Terminal or Command Prompt and typing
python3 -m pip install kivy
or
python3
then
>>> pip install kivy
I used another IDE called Mu Code (for Python) and tried it there. If it works for one application, it should work for all of them. Some other applications (like Mu) have a feature called the REPL, a read-evaluate-print-loop, that works like a python version of the terminal.
Also, be sure to check that you have correctly installed the latest version of Python. As of time of writing, the most current Python version is 3.10.5. You can download it from https://www.python.org/downloads/.
You can also try using the Python IDLE.
You can check if it's installed by using python3 -m kivy at the command line.
In the end, what worked for me was a lot of troubleshooting.
Hope that was helpful.
Sorry if this is a stupid question. I use python/jupyter a lot and it's stopped working after updating from Mac OS High Sierra to Big Sur. I'm trying to figure out why, but I'm not great with command line stuff.
The problem. When I try python3, pip -v, conda, etc. it says "command not found". python still seems to run, but it's 2.7 and I know I had 3 (I probably had a few versions from untidy file systems). I want to avoid reinstalling all my packages and things again, because I know it's still there and I've done this a few times already.
Some clues. I know this OS upgrade moves me from bash to zsh. I've tried just switching back to bash with chsh -s /bin/zsh but it still says command not found. I also noticed the OS update creates a Mac HD (below System/Volumes) within my Mac HD, and in that second one seems to be still all my python3/conda/pip/etc. folders. Not sure if/how this matters. Or if this is just a path issue.
I just want to get Jupyter running again on my Mac without reinstalling all my myriad packages from square one. Any help appreciated!
After extreme toil and research, I finally found something that worked for me.
Find the location of your Anaconda3. For me it was in ~/opt/anaconda3
Open terminal and type source <location of anaconda3>/bin/activate and then in the next line, write conda init zsh
Close your terminal and open it again. You should see a prefix (base) when you open it again.
All in all, for me it was
rko3 ~ % source opt/anaconda3/bin/activate
rko3 ~ % conda init zsh
Let me know if this works for you!
PS. You may be tempted to change $PATH variables. Anaconda advises against that. Use this reference instead that suggests the above. https://docs.anaconda.com/anaconda/install/mac-os/
I've just resolved this exact issue on my machine after upgrading to Big Sur from Mojave.
The issue: MacOS, as of Catalina, no longer lets you use the system root folder. Anaconda used to install in this folder. After upgrading from Mojave to Big Sur, you'll likely find your anaconda3 folder, including all your environments and packages, located here: /System/Volumes/Data/anaconda3.
Here is what to do to fix it:
Open Terminal
Move the anaconda3 folder:
sudo mv /System/Volumes/Data/anaconda3 ~/
Download Anaconda's Conda Prefix Replacement (crp) tool:
curl -L https://repo.anaconda.com/pkgs/misc/cpr-exec/cpr-0.1.1-osx-64.exe -o cpr && chmod +x cpr
Run the CRP tool (this will take a few minutes):
./cpr rehome ~/anaconda3/
Source anacoda3
source ~/anaconda3/bin/activate
Initiate conda
conda init
Quit Terminal and open it again.
Edit: Someone didn't like that I ended this answer with "That's it! Enjoy". In the scenario described, the steps above were indeed all it took to resolve the issue. If you're experiencing the same issue, I hope this helps resolve it, so you can get back to enjoying your updated OS.
Seems like your environement is not activated. Zsh sources ~/.zshrc while bash sources ~/.bashrc.
You can copy lines related to conda from your ~/.bashrc to your ~/.zshrc.

Open the Anaconda navigator and click on the Environments section. There you will see the base (root) and a green triangle next to it.
Click on the triangle and select Open Terminal.
Now, in the terminal you will be already in the necessary directory for anaconda and you can then update any packages.
For example, just by writing conda update --all you can update all packages available for updates.
I am very new to python and plan to use psychopy quite a lot. I am on a work computer but have full admin rights.
Psychopy came with python version 2.7.11 and includes setuptools already.
I am trying to install the selenium module, but having trouble getting pip to work at all.
In cmd, it is recognising the 'python' command, so I know python is in my path.
I get the message "can't open file 'pip': [Errno2] No such file or directory" from:
python pip install selenium
I get " 'pip' is not recognised as an internal or external command" from:
pip install selenium
When I change directory to where pip is located, I get:
Fatal error in launcher: Unable to create process using '"'
Using pip2 makes no difference.
It seems a simple thing but where am I going wrong with this?!
I never really got to the bottom of this, but this is what I found out and here are the commands that worked for me in Windows. Be aware that I am far from expert!
To run python scripts (*.py) from command line (cmd) then C:\PsychoPy2 and C:\PsychoPy2\DLLs need to be in path. ('Path' contains directories or file extensions that can be more globally accessed, i.e. do not require you to change the prompt to the relevant directories first).
To check, open cmd and either type echo %PATH% or just type python. (If python starts, the line will say >>>. You can exit by typing quit())
To add to path, get properties of computer, then advanced system settings, then environment variables.
To check pip.exe (a sort of installation wizard) is installed, either search for the file, or check C:\PsychoPy2\Scripts for it. This may also need to be in path.
To reinstall the latest versions of pip and setup tools, I went to cmd and typed:
python -m pip install -U pip setuptools
If the same code did not work for other modules (which in my case was due to network access), then I downloaded the wheel file (*.whl) for that module (from their website) and ran the following code:
python -m pip install c:/modulename.whl
These may not be the correct ways of doing things, but they worked for me when I couldn't get other ways to work!
I've just had the exact same issue with the pip install, and a conflict with PsychoPy installations. I think it's because python automatically wants to call on the path that's been set by Psychopy, so it can't get to the 'pip' folders that for me, remain in a temporary/hidden file. This wasn't intuitive for me - on any machine without psychopy python just 'works' when you download it.
In various educational guides, I have been guided to install Python modules with an easy one-line command entered in the terminal: pip install whatever
Well, when I type "pip install" it is not found.
Elsewhere in Stack Overflow the following instructions have been given:
Use apt-get -- but I am not using linux
Use easy-install pip -- but
it also produces command not found.
Use easy-install3 pip -- same problem: command not found.
Does PIP not install when you install Python 3.6?
Do I really have to edit the path myself - it seems to me, if necessary, the developers who created the installer would have done this and the path would have been updated when Python was installed.
Poking around the hidden system folders in OS X, I see that there is an alias called pip3.6 in usr/local/bin that was created a week ago when I installed Python 3.6.
I would try:
pip3.6 install whatever
Right, worked it out now.
Pip is installed when Python 3.6 is installed - but instead of typing "pip install", you type:
pip3.6 install <ModuleYouWant>
I guess this is so people can run Python 2.7 and 3.6 simultaneously.. it'd be nice if it were a little more intuitive though, or there were some instructions, or it just worked as pip gave you the option "2.7 or 3.6?"
For those OS X users in the dark like I was, please note that system files like the usr folder can be seen in Finder if you press Command+Shift+G then in the dialog box that pops up type /usr (There are other ways to see hidden folders too).
