conda-forge安装后Sagemath Jupyter内核安装错误

Question

因此，我使用conda install sage python jupyterlab通过anaconda安装SageMath。

然后，我通过jupyter kernelspec install --user ~/miniconda3/envs/sage/share/jupyter/kernels/sagemath安装this thread中的sage jupyter内核。

但此命令失败，并显示以下错误

Traceback (most recent call last):
  File "/Users/llamagod/miniconda3/envs/sage/bin/jupyter-kernelspec", line 10, in <module>
    sys.exit(KernelSpecApp.launch_instance())

    raise Error(errors)
shutil.Error: [('/Users/llamagod/miniconda3/envs/sage/share/jupyter/kernels/sagemath/doc', '/Users/llamagod/Library/Jupyter/kernels/sagemath/doc', "[Errno 2] No such file or directory: '/Users/llamagod/miniconda3/envs/sage/share/jupyter/kernels/sagemath/doc'")]

我尝试将$SAGE_LOCAL/share/doc符号链接到该目录，但得到了相同的错误。

SageMath 9.2、JupyterLab 3.0.16

这是一个已知的问题吗？

Answer 1

最后，我使用了this page中描述的另一种方法来安装内核，并避免复制文档。

ln -s `sage -sh -c 'ls -d $SAGE_LOCAL/share/jupyter/kernels/sagemath'` $HOME/miniconda3/envs/sage/share/jupyter

因此，我现在可以在conda环境中从jupyter运行sagemath内核。
