错误conda.core.link:_execute（701）：更新conda包时出错

Question

我无法更新我的基本conda环境。有人知道如何解决这个问题吗

conda update -n base --all

它返回：

我在互联网上找不到任何解决方案。如果有任何方法来解决这个问题，而不必重新安装康达将不胜感激。谢谢大家!

Answer 1

我有一个类似的问题，但我解决了。这是我的解决办法。 操作系统：MacOSX

1. 运行以下命令

   conda install python.app -c conda-forge -v

2. 在输出中，您将发现以下内容

   Verifying transaction: ...working... done
   Executing transaction: ...working...
   ===> UNLINKING PACKAGE: 
    https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/osx-64::certifi-2021.10.8-py37hecd8cb5_0 
    <===
   
     prefix=/Users/huaweiwang/opt/anaconda3
   ===> LINKING PACKAGE: conda-forge::certifi-2021.10.8-py37hf985489_0 <===
   
   prefix=/Users/***/opt/anaconda3
   source=/Users/**/opt/anaconda3/pkgs/certifi-2021.10.8-py37hf985489_0
   ...
   
   

3. 我们只关心前缀prefix=/Users/***/opt/anaconda3

4. 您将在$prefix/python.app/Contents/中找到lib目录

5. 将lib重命名为lib.bak

6. 再次安装python.app，您将成功

   conda install python.app -c conda-forge -v
