I followed all the steps specified in the ReadMe documentation. I have installed MiniForge, Mamba and checkout the repository. 

I then followed the installation instructions specified in the README.md file and executed the below command

```sh
python -m pip install -ve . --no-build-isolation --config-settings=editable-verbose=true
```
And was facing several errors. After inspecting the logs I found out that they were ModuleNotFound errors so I inspected more and found I have to install all the requirements first

```sh
python -m pip install -r requirements-dev.txt
```

I have updated the ReadMe accordingly so, new comers won't stumble like me!

Updated document will have the following commands now

```sh
python -m pip install -r requirements-dev.txt
python -m pip install -ve . --no-build-isolation --config-settings=editable-verbose=true
``` This is incorrect, sorry. The instructions are for general users, you are making them install the dependencies for people who contributes to pandas, which doesn't make sense. Closing. It had this instructions for development mode which I tried and it failed. Instructions were partial

In **README.md**:

or for installing in [development mode](https://pip.pypa.io/en/latest/cli/pip_install/#install-editable):

python -m pip install -ve . --no-build-isolation --config-settings=editable-verbose=true You are correct, sorry, I reviewed this PR too quick.

@lithomas1, I think this is failing since we moved to Meson. Shouldn't pip be able to find the dependencies it needs? When installing in editable mode pip fails because `mesonpy` is not found, and after installing it manually it fails because ofther deps like jinja. @lithomas1 Should I remove and send pull request? Yes, feel free to edit this same branch/PR and remove that block.
