推荐答案

就我而言，pip3 uninstall conda 解决了问题.

In my case, pip3 uninstall conda solved the problem.

原因是 miniconda 试图使用 pip 的可执行文件.当我首先使用 pip3 然后使用 miniconda 安装 conda 时发生了这种情况.

The reason was miniconda trying to use pip's executables. It happened when I installed conda using pip3 first and then using miniconda.
