error: legacy-install-failure when installing apex

I followed the method(https://github.com/NVIDIA/apex#quick-start) to install apex with CUDA and C++ extensions(Linux), but I got the error in the picture.
Local environment version: pytorch:1.13.1+cuda:11.7

Command:

git clone github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./

Error:

Using pip 23.0.1 from /home/kang/miniconda3/envs/atlop/lib/python3.9/site-packages/pip (python 3.9)
WARNING: Implying --no-binary=:all: due to the presence of --build-option / --global-option / --install-option. Consider using --config-settings for more flexibility.
DEPRECATION: --no-binary currently disables reading from the cache of locally built wheels. In the future --no-binary will not influence the wheel cache. pip 23.1 will enforce this behaviour change. A possible replacement is to use the --no-cache-dir option. You can use the flag --use-feature=no-binary-enable-wheel-cache to test the upcoming behaviour.

note: This is an issue with the package mentioned above, not pip.

Please help me to explain the cause of the error and how to solve it (could it be a version problem, he stressed that it is a packbag problem, could it be a problem with apex source code?)

The following error is being printed:

It means that the pip install command needs the package packaging to be already installed to correctly install apex.

Install the missing package before installing apex:

pip install packaging
# Then, your commands
git clone github.com/NVIDIA/apex
cd apex
pip install -v --disable-pip-version-check --no-cache-dir --global-option="--cpp_ext" --global-option="--cuda_ext" ./
