卸载anaconda后诗歌和python问题（Mac OS）

Question

我最近卸载了 anaconda 并重新安装了它的 M1 版本，因为我之前错误地使用了它的 intel 版本（我遵循了官方指南）。

我有一些使用诗歌的项目，我之前使用

pip install poetry

安装在 conda 环境中。我想在新的 conda 环境中重复此过程，但收到以下错误消息：

  note: This error originates from a subprocess, and is likely not a problem with pip.

我在输入

python --version

时也收到类似的错误消息：

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun

但是当我输入

python3 --version

时我得到：

Python 3.12.1

我注意到的另一件事是，当我执行

poetry

时，我得到以下输出，其中 sys.path 似乎指向不再存在的 python 版本（我现在在 anaconda3/lib 中有 python3.11 文件夹）

我真的不知道如何将所有这些点连接在一起，所以任何帮助将不胜感激。本质上，我希望能够再次安装诗歌并在我的项目中使用它。谢谢

第一个错误表明您缺少

xcrun

，请尝试通过运行

xcode-select --install

来（重新）安装 xcode，看看是否可以解决该问题。
