conda - 使用 conda 更新 conda 时出现 UnsatisfiableError

Question

尝试使用命令 conda update conda 从终端更新 conda 时出现错误.它在说:

Solving environment: failed

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

与 conda --version它打印出来 conda 4.5.4和 conda list正在工作。任何人都可以知道如何解决这个问题吗？查看 conda 安装路径 /home/samuel/anaconda3/conda-meta我找不到任何名为 pinned 的文件。

Answer 1

如果其他人偶然发现此问题，我可以通过执行以下操作来解决此问题，而无需重新安装 anaconda:

先删除conda-canary从您的固定包中:

$ conda config --system --remove pinned_packages conda-canary::conda

然后像往常一样更新 conda:

$ conda update conda

据我目前所知，这并没有产生任何意外后果，应该比卸载和重新安装 anaconda 更容易。
