任何 anaconda 命令返回错误“无法从‘集合’导入名称‘序列’”

Question

当我尝试在终端中运行任何 anaconda 命令（conda、upyter notebook、pip3...）时，它会抛出以下错误：

>conda
Traceback (most recent call last):
  File "/Users/thejavanoob/anaconda3/lib/python3.11/site-packages/conda/exception_handler.py", line 17, in __call__

During handling of the above exception, another exception occurred:

我尝试重新安装 anaconda，问题仍然存在。只运行 python 就可以了，在 anaconda navigator 中运行 Jupyter Notebook 也可以正常工作。

collections.Sequence

在 Python 3.7 中已弃用，但您正在使用 Python 3.11 site-packages 目录运行带有 Python 3.12 解释器的系统范围内安装的 Jupyter。这真是一团糟...:)

我建议从头开始：

• 卸载 Anaconda 的所有痕迹，确保

  /Users/thejavanoob/anaconda3/

  不是一个东西（您可以重命名它，而不是删除它）——如果成功，您根本不应该在命令行上有

  conda

  可用
• 确保 Anaconda 等地方没有留下任何错误的痕迹。你的系统

  PATH

• 卸载已在系统范围内安装的 Python 软件包，例如

  jupyter

  （请参阅

  pip list

  ）；如果这有效，那么您根本不应该在命令行中使用

  jupyter

一般来说，除非你知道你需要 Anaconda，否则我可能会避免它带来的额外复杂性。
