python - conda 错误 : Cannot link a source that does not exist

Question

我正在尝试安装 geopandas，我通常会通过 pip 来安装，但它似乎与依赖关系很挣扎，所以我尝试通过 conda 包管理器进行安装。

一切顺利，直到我收到此错误:

Conda error: Cannot link a source that does not exist C:\ProgramData\Anaconda3\Scripts\conda.exe

我检查过，在指定的文件夹中有 conda.exe。我也在 PATH多变的。

我还查看了有关此错误的其他问题并尝试了建议的解决方案:

conda clean --all --yes
conda update conda
conda update anaconda

然而我每次仍然遇到同样的错误。任何人都知道解决此问题的其他方法吗？

谢谢!

编辑:

我尝试使用这两个选项安装 geopandas:

conda install geopandas
conda install --channel conda-forge geopandas

conda info 的输出:

似乎在以下之后工作:

conda install tqdm -f

conda update conda 在此之后工作，如果以管理员权限执行。
