CondaValueError：格式错误的版本字符串“〜”：无效字符

Question

我的conda收到格式错误的版本字符串错误。我不知道如何调试此或如何检查它。

有人可以帮忙吗？GitHub讨论了这个问题，但是我还没有看到任何修复。

-bash-4.1$ conda install -c bioconda pysam
Solving environment: failed



 1. CondaValueError: Malformed version string '~': invalid character(s).

This looks like it was fixed with Conda 4.6.0. Upgrading your Conda should resolve the issue.

conda upgrade -n base conda

If you have trouble solving environment, I suggest trying

conda upgrade -n base -c defaults --override-channels conda

This will exclude all other channels during the solving process, and helps because having too many options to prune is one of the main reasons for slow solves.
