pip安装PyVCF后有问题：ImportError: cann

问题

Python通过pip安装PyVCF成功，但运行脚本时出现问题：

File "/home/theo/anaconda3/lib/python3.9/site-packages/vcftoolz/vcftoolz.py", line 19, in <module>
    import vcf
  File "/home/theo/anaconda3/lib/python3.9/site-packages/vcf/__init__.py", line 166, in <module>
    from parser import Reader, Writer
ImportError: cannot import name 'Reader' from 'parser' (/home/theo/anaconda3/lib/python3.9/lib-dynload/parser.cpython-39-x86_64-linux-gnu.so)

解决

使用conda重新安装：

conda install --channel "conda-forge" pyvcf
