python - Anaconda3 - 属性错误 : 'dict' object has no attribute 'rsplit'

Question

我正在通过网络浏览器在本地运行 Anaconda3。每次我去“Conda”部分查看已安装的包(位于 http://localhost:8888/tree#conda)时，我都会收到 An error occurred while retrieving installed packages。内部服务器错误。

查看日志，这是目前正在发生的事情。有什么想法吗？

Answer 1

也许这应该是一个评论，但我没有足够的声誉。

这是一个 reported bug in nb_conda . conda 的 package info 的输出格式发生了变化，需要对 nb_conda 进行适配。已经有一个 pull request that fixes this但我在任何 channel 都找不到零钱。

安装包含修复程序的分支目前有帮助:

pip install git+https://github.com/Anaconda-Platform/nb_conda.git@d488d9e --upgrade

--upgrade 是可选的，我需要它，因为我安装的版本相同。

从 conda-forge channel 安装 nb_conda_kernels(可能已将 nb_conda 作为依赖引入)，如 motivic 所述对我的情况没有帮助，但如果那里的软件包包含修复程序，应该可以工作。
