Question

我正在尝试安装pypyodbc软件包，但我遇到了错误：

(base) C:\>conda install -c zegami pypyodbc
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - backports.functools_lru_cache
  - pypyodbc
Use "conda info <package>" to see the dependencies for each package.

我不明白这里的问题是什么，或者为什么backports.functools_lru_cache会产生任何影响。我也尝试过不同的pypyodbc贡献，包括来自CIT和mbonix的贡献。在每种情况下导致错误的特定包是不同的（分别是urllib3和期货），但结果是相同的。无论如何，这是conda信息的输出。我很感激能得到的任何帮助！

谢谢，布拉德

为什么在尝试使用conda安装pypyodbc时会出现不可满足的错误？
