I am new to Python and try to install Jupyter Notebook from within a Windows command prompt window using:

pip install jupyter

But after a couple of minutes of downloading, an error message is displayed as shown below:

  Installing build dependencies ... done
  Getting requirements to build wheel ... done

I have attached here just the last part of the error output.

How to fix this error for a successful installation of Jupyter Notebook?

EDIT1: I installed the Rust package from the link in the error message. After that I tried installing Jupyter Notebook once again, and this time after proceeding a few steps further than before, it output another error:

  • You can install [Anaconda](https://docs.anaconda.com/anaconda/install/windows/), Jupyter comes with it. – nobleknight May 01 '21 at 06:21
  • Which pages have you read from [Jupyter Documentation](https://jupyter.readthedocs.io/en/latest/)? Have you clicked on [Project-wide Documentation](https://jupyter.readthedocs.io/en/latest/)? Have you clicked on [Get started with Jupyter Notebook](https://jupyter.readthedocs.io/en/latest/content-quickstart.html)? Have you clicked on [Are You Ready to Install Jupyter?](https://jupyter.readthedocs.io/en/latest/tryjupyter.html#are-you-ready-to-install-jupyter) Have you clicked on [Installation Guide](https://jupyter.readthedocs.io/en/latest/install.html#install)? – Mofi May 01 '21 at 09:22
  • Or have you read at least the page [Installing the Jupyter Software](https://jupyter.org/install)? Do you know how environment variables are managed on Windows as described extensively by my answer on [What is the reason for "X is not recognized as an internal or external command, operable program or batch file"?](https://stackoverflow.com/a/41461002/3074564) It often fails to install multiple Python packages within __one__ command prompt window in series. – Mofi May 01 '21 at 09:29

    We shouldn't need rust (cargo) for python packages .. seems wrong. – kev Feb 15 '23 at 04:24
  • @kev I've got the same thing now suddenly, after using Jupyter for years. Where is this coming from? Do I really need to install Rust now (where how why, how do I maintain it) in order to use Jupyter? Will this now start failing in all my CI and Binder installs? – orome Feb 20 '23 at 14:14

Upgrade your pip first:

pip install --upgrade pip

Then:

pip install jupyter

I'reached this post after failing to install notebook on a 32-bit python 3.8.3 execution. And as far as I found, pywinpty, which is a dependence, does not support 32-bit executions (see sources below).

I solved the problem by installing python on its 64-bit version.

Do

pip install wheel

and try again. It worked for me.

What to do:

  1. Check if your python is 64-bit version. If no, go to python site (for example, here is the link to download 3.7.9. Just click at the version that has label "for AMD64/EM64T/x64", do it with any version you wish, just I don't like to use the newest version). Remove yours (with the uninstall file) and download this. Don't forget to put the checkmark near "Add PATH" below;
  2. Download Rust (the description is inside) - you need some files. Check the PATHs - if you want to change them, do it (the names of the variables and where they are - both are written, you can search in the Internet how to change PATH var's (for example));
  3. Go to Windows Shell with admin mode (Win+X and you get the field) - here is the most comfortable place to work;
  4. Go to your python.exe (for example, my way is C:\Users\user\AppData\Local\Programs\Python\Python37) - just for sure;
  5. python.exe python -m pip install --upgrade pip;
  6. python.exe pip install jupyter;
  7. If an error was returned that contains the missing of wheel, try to download it: python.exe pip install wheel.

Donwload any library you miss during installation and continue since the step you stopped at.

Try using Anaconda. link to install conda https://www.anaconda.com/products/individual then cmd : conda install numpy cmd: conda install jupyter cmd : jupyter notebook

The error message looks quite clear, you needs to install Cargo via https://rustup.rs/

    I installed following the link, but still I got other errors as I have attached in the edit – Jazz May 01 '21 at 07:01

I have faced the same issue when I'm using vscode. The simplest solution is to use conda instead of pip

conda install jupyterlab

  • This does not provide an answer to the question. Once you have sufficient [reputation](https://stackoverflow.com/help/whats-reputation) you will be able to [comment on any post](https://stackoverflow.com/help/privileges/comment); instead, [provide answers that don't require clarification from the asker](https://meta.stackexchange.com/questions/214173/why-do-i-need-50-reputation-to-comment-what-can-i-do-instead). - [From Review](/review/late-answers/32374699) – Trenton McKinney Aug 05 '22 at 22:55
  • This is not helpful. If they have the Anaconda distribution, `jupyterlab` is already installed, and `conda install jupyterlab` is not required. It's clear from the path in the OP, that Anaconda is not being used. As such, this does not answer the question that was asked. Additionally, there is already a downvoted [answer](https://stackoverflow.com/a/67343436/7758804) to use Anaconda, and more appropriately, a [comment](https://stackoverflow.com/questions/67343397/how-to-fix-errors-occurring-on-installation-of-jupyter-notebook/73182010#comment119033197_67343397) doing the same. – Trenton McKinney Aug 05 '22 at 23:46
