最近好像很多人出現了這個錯誤信息：
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.
我是因爲升級了conda纔出現這個信息的，在網上查瞭解決方法
conda activate base # or just conda deactivate
conda update conda-build
注意要在base裏update，之前一直在某個虛擬環境中update的，不管用
