自己的测试环境 Ubuntu20.04 ROS-Noetic
一、问题描述
自己在通过 pip install 安装module时 使用的是 pip install mmcv遇到如下问题
ImportError: cannot import name packaging from pkg_resources 出现该问题时的终端的全部输出如下
Using cached mmcv-2.2.0.tar.gz (479 kB)Preparing metadata (setup.py) ... errorerror: subprocess-exited-with-error× python setup.py egg_info did not run successfully.│ exit code: 1╰─ [10 lines of output]/tmp/pip-install-qm5a01q8/mmcv_417ac91e439f41a1b12309217221d376/setup.py:5: DeprecationWarning: pkg_resources is deprecated as an API.

hint: See above for details.报错截图如下
二、解决方法
上述的报错信息表明在安装 mmcv 时出现了 pkg_resources 模块的问题。具体来说似乎是 packaging 模块无法从 pkg_resources 中导入。 解决方法如下 安装packaging 模块 pip install packaging 更新 setuptools 和 pip: pip install --upgrade setuptools pip然后再次运行自己的安装程序即可解决问题。自己是重新运行 pip install mmcv, 就能安装成功了。
