Hello all，

- MNE version: 1.3.1
- operating system: macOS Ventura 13.3

I am trying to upgrade mne to the development version in the Terminal, but the upgrade failed.

```python
pip install -U --no-deps https://github.com/mne-tools/mne-python/archive/main.zip

```

```python
  Preparing metadata (setup.py) ... error
  error: subprocess-exited-with-error
  
  × python setup.py egg_info did not run successfully.
  │ exit code: 1
  ╰─> [30 lines of output]

      Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.
      
      For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj
      [end of output]
  
  note: This error originates from a subprocess, and is likely not a problem with pip.

this part of the output suggests that you should do

```python
pip install -U --no-deps git+https://github.com/mne-tools/mne-python.git#egg=proj

```

did that not work?

Thanks Dan!

I tried `pip install -U --no-deps git+https://github.com/mne-tools/mne-python.git#egg=mne` and it finally worked.
