I am using the OS Ubuntu 20.04 and I have installed Anaconda Python. I am following a course in orielly and the instructor asked to execute the below 2 commands, on trying it I am getting the respective error message,
command:
jupyter labextension install jupyter-matplotlib
error:
An error occured.
ValueError: "jupyter-matplotlib" is not a valid npm package
command :
jupyter labextension install #jupyter-widgets/jupyterlab-manager
error:
An error occured.
ValueError: "#jupyter-widgets/jupyterlab-manager" is not a valid npm package
I have installed nodejs already, for your information.
Open Anaconda prompt and just run the command:
pip update --all
pip install matplotlib

I was previously running into environment inconsistencies after downloading tensorflow with pip in a conda environment, and after several hours of frustration, decided deleting anaconda/miniconda and python and starting from scratch would be my best option to get python working again (The inconsistencies were causing a plethora of issues with loading other modules like numpy, etc).
After downloading Python version 3.9.10 directly from https://www.python.org/downloads/macos/, I wanted to see if I could start using Python again in a Jupyter notebook in VS Code. When I try to run a simple print('hello world') in a python chunk I (unsurprisingly) get the following error:
Jupyter cannot be started. Error attempting to locate jupyter: Running cells with 'Python 3.9.10 64-bit' requires notebook package.
Run the following command to install 'jupyter and notebook' into the Python environment.
Command: 'python -m pip install jupyter notebook -U'
I was pretty much expecting this error, since I knew I had deleted all packages when deleting Anaconda and Python.
However, when I try running python -m pip install jupyter notebook -U in the terminal I ultimately get the following error:
xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
error: command '/usr/bin/gcc' failed with exit code 1
[end of output]
note: This error originates from a subprocess, and is likely not a problem with pip.
error: legacy-install-failure
× Encountered error while trying to install package.
╰─> psutil
note: This is an issue with the package mentioned above, not pip.
Any help or insight is greatly appreciated! I am on MacOS (M1) if that is useful information.
The problem seems to be with the python3 distribution that comes with MacOSX Command Line Tools. Well, at least that same error was gone after following these steps.
So, to fix the problem I installed python3.9 (I presume you can change 3.9 to your desired version, e.g. 3.8 or 3.10) using Homebrew.
Install Homebrew (to check if it's installed already just type brew --version in the terminal):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Install python3.9
brew install python#3.9
Create your virtual environment
python3.9 -m venv myvenv
Activate the virtual environment with source myvenv/bin/activate
Finally, install Jupyter using
(myvenv) pip install jupyter notebook
I have the same problem when installing the Jupyter notebook on MacOS 12.5 M2 chip. It turns out that the error is caused by not having GCC on my mac to run the wheel for installing the psutil package because for some reason I removed my XCode from my Mac. So I installed XCode from AppStore and opened XCode after the installation to agree to its terms and conditions. After Xcode went through the setup process I tried pip install jupyter again and it worked well.
In my case, I just opened the XCode, accept the terms and the installation proposed, and tried to install the jupyter again and it worked!
It seems to be very particular about the version of python installed. I set up a fresh installation on a new box this morning and put 3.11 on there. pip install jupyterlabs gave me the same error as you got. I then uninstalled python and installed an earlier version, and now it works.
PS the older version that worked for me is 3.10.8
I am trying to install to oct2py package to import in my python script. However whenever I run the command pip install oct2py I get the following error:
Fatal error in launcher: Unable to create process using '"c:\python37\python.exe" "C:\Program Files\Python37\Scripts\pip.exe" ': file cannot be found.
How can I install oct2py?
Found the answer
Deinstalled python and reinstalled it. I checked the environment variable and changed it from this one : 'C:\Program Files\Python39' to this one 'C:\Users\lsee\AppData\Local\Programs\Python\Python39'.
Is unable to locate your pip installer, easy fix is unusually to either upgrade or test pip :
# to upgrade your pip
python -m pip install --upgrade pip
pip --version
# test you have pip in your machine
If your pip version is showing that means you have it installed, it could be a problem activating your virtual environnement, or your path.
It says the file cannot be locate, are you sure your path for Python and pip is correct ?
Try:
python -m pip install oct2py
This should work (as python -m pip install gave not errors)
I can't install any python module or library using pip on command prompt, whenever I tried to install any module the error occurs. I have the latest version of conda in my system.
The error is as-
Unable to create process using 'C:\Users\UDIT DEO\Anaconda3\python.exe
"C:\Users\UDIT DEO\Anaconda3\Scripts\pip-script.py" install keras
I'm trying to install new modules in python 3 and when I run python -m pip install filename on my win10 machine then I'm getting:

I tried to run PowerShell as an admin but the problem persists. I also tried to run this command in the cmd.
I received the same error message when executing a pip install numwords2 from the Pycharm console.
I then upgraded pip, using:
python -m pip install --upgrade pip
which uninstalled pip-19.1.1 and replaced it with pip-19.3.1.
The next whack at pip install worked well.
termcolor is quite old, the last release 1.1.0 was in 2011. There is a report that Python 3.6+ broke termcolor.
My recommendation is to try console.
I'm following instructions to create a Tensorflow environment for a Machine Learning course, with python 3.5, ipython and jupyter.
I created a Tenserflow environment with python 3.5 using conda create -n tensorflow python=3.5. That worked.
Then I ran conda install -c conda-forge tensorflow. That also worked.
Then I installed ipython with conda install ipython, which also worked fine.
However, when I ran pip3 install jupyter, I got error message bash: pip3: command not found.
I found a few posts about variations on pip3 problems and (within the Tensorflow environment):
When I type pip --version, it tells me I have version 8.1.2
When I try locate pip3, I get WARNING: The locate database (/var/db/locate.database) does not exist
I tried using pip-3.2 as recommended in one of the other questions' solutions (which worked for that OP), and I get the same command not found error message.
I'm using OS X 10.8.5
pip is different from pip3. So you might need to install it if it can't be found. If it is installed run this:
sudo updatedb
this will update the locate function.
if you're using conda why do you want to install it with pip anyways?
Jupyter is the new version of ipython. running conda install ipython installs ipython (now jupyter).
