我试图使用以下命令更新conda：
~$ conda update conda
它输出以下消息：
WARNING conda.base.context:use_only_tar_bz2(632): Conda is constrained to only
using the old .tar.bz2 file format because you have conda-build installed,
and it is <3.18.3. Update or remove conda-build to get smaller downloads
and faster extractions.
