Remember to:

Ask your Python question, not if you can ask or if there's an expert who can help.
Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Are you on VSCode? it may be as simple as selecting another interpreter (near the bottom right)

uneven dock Jul 25, 2025, 6:59 PM

#

yeah, alright ill give tht a go

#

yep that seems to have workd, thanks haha

spiral arch Jul 25, 2025, 7:00 PM

#

Anytime haha

uneven dock Jul 25, 2025, 7:01 PM

#

spiral arch Anytime haha

wait, it only works with python 3.9.6 which doesn't support qiskit, any ideas on how i can get it to work with my 3.11.11 intepreter?

spiral arch Jul 25, 2025, 7:01 PM

Are you on windows?

What does python -V, pip -V and pip3 -V display?

uneven dock Jul 25, 2025, 7:03 PM

#

results only show for pip3

#

bit of a long msg tho, want me to send?

spiral arch Jul 25, 2025, 7:03 PM

#

It shouldn't be long, maybe it's pip3 -v?

#

(lower case v)

uneven dock Jul 25, 2025, 7:04 PM

#

pip 21.2.4 from /Library/Developer/CommandLineTools/Library/Frameworks/Python3.framework/Versions/3.9/lib/python3.9/site-packages/pip (python 3.9)

spiral arch Jul 25, 2025, 7:04 PM

#

Does python3 -V print anything?

uneven dock Jul 25, 2025, 7:06 PM

#

spiral arch Does `python3 -V` print anything?

Python 3.9.6

spiral arch Jul 25, 2025, 7:07 PM

#

How'd you install 3.11?

uneven dock Jul 25, 2025, 7:07 PM

#

uhh, i cant really remember

#

thats my interpreters

spiral arch Jul 25, 2025, 7:08 PM

#

you have pyenv so that's great, one sec ill go through the docs

uneven dock Jul 25, 2025, 7:08 PM

#

alright thanks

spiral arch Jul 25, 2025, 7:08 PM

#

Try running pyenv global 3.11.11

#

That should make 3.11 your default instead of your system 3.9 python

uneven dock Jul 25, 2025, 7:09 PM

#

zsh: command not found: pyenv

rugged meteor Jul 25, 2025, 7:11 PM

#

do you have pip installed?

uneven dock Jul 25, 2025, 7:11 PM

#

yeah

#

well, pip3

spiral arch Jul 25, 2025, 7:11 PM

#

what does echo $PATH print for you?

rugged meteor Jul 25, 2025, 7:12 PM

#

uneven dock yeah

in cmd, do "py -m pip install --upgrade pip", then do "py -m pip install [package_name]"

uneven dock Jul 25, 2025, 7:12 PM

oh my bad

uneven dock Jul 25, 2025, 7:12 PM

np

spiral arch Jul 25, 2025, 7:14 PM

#

Homebrew usually symlinks python3 and pip3 - it's odd that it didn't

#

Does echo $PYENV_ROOT print anything?

rugged meteor Jul 25, 2025, 7:14 PM

#

what library are you trying to download?

spiral arch Jul 25, 2025, 7:14 PM

#

its probably simpler to re-install pyenv and set its version

uneven dock Jul 25, 2025, 7:15 PM

#

spiral arch Does `echo $PYENV_ROOT` print anything?

nope

uneven dock Jul 25, 2025, 7:15 PM

#

rugged meteor what library are you trying to download?

qiskit and matplotlib

uneven dock Jul 25, 2025, 7:15 PM

#

spiral arch its probably simpler to re-install pyenv and set its version

alright shall i give that a go

rugged meteor Jul 25, 2025, 7:16 PM

#

try "python3 -m pip install <package-name>"

uneven dock Jul 25, 2025, 7:17 PM

#

ive just switched back to my pyenv interperter and now its saying numpy cant be rsolved even tho it was fine before

#

spiral arch Jul 25, 2025, 7:17 PM

#

https://github.com/pyenv/pyenv#a-getting-pyenv from this you should need to run the following:

brew update
brew install pyenv --head

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo '[[ -d $PYENV_ROOT/bin ]] && export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(pyenv init - zsh)"' >> ~/.zshrc

exec "$SHELL"

pyenv global 3.11.11

you can run these one by one

uneven dock Jul 25, 2025, 7:18 PM

#

so just run each one

spiral arch Jul 25, 2025, 7:18 PM

#

yeeeep

uneven dock Jul 25, 2025, 7:18 PM

#

okay

spiral arch Jul 25, 2025, 7:18 PM

#

After you do that, try running the version commands I posted earlier to make sure everything's in-sync

rugged meteor Jul 25, 2025, 7:19 PM

#

bro do you have multiple python versions? like 1.12 and 1.13

uneven dock Jul 25, 2025, 7:19 PM

#

yeah i think so

#

i have 2 interpreters with 2 dif versions

rugged meteor Jul 25, 2025, 7:20 PM

#

try changing your interpreter

uneven dock Jul 25, 2025, 7:20 PM

#

i tried but the library i want to use doesnt work with python 3.9.6

#

which is the only working interpreter for that libarry

#

@spiral arch ive tried running this echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc got an error message then sent it agin and now it does nothing

spiral arch Jul 25, 2025, 7:22 PM

#

that shouldnt error out

uneven dock Jul 25, 2025, 7:23 PM

#

zsh: no such file or directory: /Users/emlynphoenix/.zshrc/Users/emlynphoenix/.pyenv/versions/3.11.11/bin/python

spiral arch Jul 25, 2025, 7:24 PM

#

are you running those one-by-one? order matters

#

that error also doesnt seem to be caused by the command you just sent

uneven dock Jul 25, 2025, 7:24 PM

#

yeah i ran one by one

spiral arch Jul 25, 2025, 7:25 PM

#

could you paste a terminal dump into the pastebin maybe? from the point where you started running these

uneven dock Jul 25, 2025, 7:25 PM

#

echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshr is that the correct command

uneven dock Jul 25, 2025, 7:25 PM

#

spiral arch could you paste a terminal dump into the pastebin maybe? from the point where yo...

oh i kinda killed to termincal cuz when i tried to send that command again nothing would happen

spiral arch Jul 25, 2025, 7:25 PM

#

uneven dock `echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshr` is that the correct command

yes, that adds a line into your shell configuration file

#

try cat ~/.zshrc

#

and just paste thee last few lines of the output

uneven dock Jul 25, 2025, 7:26 PM

#

export PYENV_ROOT="$HOME/.pyenv"
export PYENV_ROOT="$HOME/.pyenv"
export PYENV_ROOT="$HOME/.pyenv"
export PYENV_ROOT="$HOME/.pyenv"
export PYENV_ROOT="$HOME/.pyenv"

spiral arch Jul 25, 2025, 7:26 PM

#

yep that command won't produce any output, but it worked

uneven dock Jul 25, 2025, 7:26 PM

#

ohh alright

#

i thought it wasnt working mb

spiral arch Jul 25, 2025, 7:27 PM

#

no worries the duplicated lines wont hurt so you can keep going

uneven dock Jul 25, 2025, 7:28 PM

#

ok ran them all

spiral arch Jul 25, 2025, 7:28 PM

#

if you didnt see any red lines youre probably good

#

you can try those version commands from earlier

#

python3, pip, python, pip3 with the -v / -V flag

uneven dock Jul 25, 2025, 7:30 PM

#

none seem to work now..

#

unless ive done smthn weird

spiral arch Jul 25, 2025, 7:31 PM

#

whoops

#

what did pyenv global 3.11.11 print?

#

you can run it again if you lost the output

uneven dock Jul 25, 2025, 7:31 PM

#

nothing

spiral arch Jul 25, 2025, 7:31 PM

#

what about pyenv versions

uneven dock Jul 25, 2025, 7:32 PM

#

spiral arch `python3`, `pip`, `python`, `pip3` with the `-v` / `-V` flag

wait they do

#

i just killed the terminal

uneven dock Jul 25, 2025, 7:32 PM

#

spiral arch what about `pyenv versions`

3.11.11 (set by PYENV_VERSION environment variable)

spiral arch Jul 25, 2025, 7:32 PM

#

do they all display 3.11.11

#

the version commands

uneven dock Jul 25, 2025, 7:33 PM

#

pip3 -V: pip 24.0 from /Users/emlynphoenix/.pyenv/versions/3.11.11/lib/python3.11/site-packages/pip (python 3.11)

python3 -V: Python 3.11.11

spiral arch Jul 25, 2025, 7:33 PM

#

great, it should be the same for pip and python too

#

well to summarize what we did

#

pyenv lets you manage python versions, so pyenv is set to 3.11.11 currently which makes that your default python version

uneven dock Jul 25, 2025, 7:34 PM

#

spiral arch great, it should be the same for `pip` and `python` too

ya it is

#

ohh ok

spiral arch Jul 25, 2025, 7:34 PM

#

sooo now you canpip install whatever packages you need and make sure to select the pyenv 3.11.11 version

#

and that should hopefully fix your errors

uneven dock Jul 25, 2025, 7:35 PM

#

if its ssying to update my pip should i?

rugged meteor Jul 25, 2025, 7:35 PM

#

i have completely lost track on what is going on here lol

uneven dock Jul 25, 2025, 7:36 PM

#

spiral arch https://github.com/pyenv/pyenv#a-getting-pyenv from this you should need to run ...

i just ran these commands

spiral arch Jul 25, 2025, 7:36 PM

#

uneven dock if its ssying to update my pip should i?

sure, usually unnecessary though

#

(optional) if your libraries work on newer python versions, you can install a newer python version through pyenv and use that - that would be recommended (it would be something like pyenv install 3.13.2 & pyenv global 3.13.2

uneven dock Jul 25, 2025, 7:37 PM

#

oh shall i do that?

#

may aswell

#

or actually

#

ill keep 3.11 for no

#

now

spiral arch Jul 25, 2025, 7:37 PM

rugged meteor i have completely lost track on what is going on here lol

No worries just make sure to keep using pyenv haha, even if you need newer versions, dont mix it with homebrew or anything else
