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

Question

我的 conda 出现格式错误的版本字符串错误。我不知道如何调试它或如何检查它。

有人能帮忙吗？ GitHub 已经讨论过这个问题，但我还没有看到任何修复。

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

Answer 1

这个looks like it was fixed with Conda 4.6.0。升级您的 Conda 应该可以解决问题。

conda upgrade -n base conda

如果遇到环境问题，建议尝试

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

这将在求解过程中排除所有其他通道，并且有帮助，因为要修剪的选项太多是求解速度慢的主要原因之一。

Answer 2

我尝试从 yaml 文件创建环境时遇到了与 conda 4.8.2 相同的问题。

加载一个不同的、已经存在的环境并再次卸载它在多个场合都成功了。

Answer 3

我需要从我的 .condarc 文件中删除 conda-forge。然后一切正常。
