[Bug] error: metadata-generation-failed

[JiBingdong]

Prerequisite

• I have searched Issues and Discussions but cannot get the expected help.
• The bug has not been fixed in the latest version (0.x) or latest version (1.x).

Task

I'm using the official example scripts/configs for the officially supported tasks/models/datasets.

Branch

main branch https://github.com/open-mmlab/mmocr

Environment

我在今天下载了最新版本的mmocr，但是按照安装教程执行pip install -v -e .出现错误

Reproduces the problem - code sample

(open-mmlab) ji@Y7000P:~/mmocr$ pip install -v -e .

Reproduces the problem - command or script

git clone https://github.com/open-mmlab/mmocr.git
cd mmocr
pip install -v -e .

"-v" increases pip's verbosity.

"-e" means installing the project in editable mode,

That is, any local modifications on the code will take effect immediately.

Reproduces the problem - error message

!!

      ********************************************************************************
      As setuptools moves its configuration towards `pyproject.toml`,
      `setuptools.config.parse_configuration` became deprecated.

      For the time being, you can use the `setuptools.config.setupcfg` module
      to access a backward compatible API, but this module is provisional
      and might be removed in the future.

      To read project metadata, consider using
      ``build.util.project_wheel_metadata`` (https://pypi.org/project/build/).
      For simple scenarios, you can also try parsing the file directly
      with the help of ``configparser``.

This is -- a caller that pip uses to run setup.py

- It imports setuptools before invoking setup.py, to enable projects that directly

import from distutils.core to work with newer packaging standards.

- It provides a clear error message when setuptools is not installed.

- It sets sys.argv[0] to the underlying setup.py, when invoking setup.py so

setuptools doesn'"'"'t think the script is -c. This avoids the following warning:

manifest_maker: standard file '"'"'-c'"'"' not found".

- It generates a shim setup.py, for handling setup.cfg-only projects.

import os, sys, tokenize

try:
import setuptools

"ERROR: Can not execute setup.py since setuptools is not available in "
"the build environment.",

I ran into the same problem, solved it by running pip install setuptools --upgrade (version 69.5.1), since the bug seems fixed in the latest version. I only get a warning about openxlab now.
