安装环境运行报错

[lzkgbld]

使用的系统是centos7.64位，Python版本3.6.8。
已经按照文档要求先使用pip install -r requirements.txt安装相关环境，但是最后Python mian.py的时候报错。
File "main.py", line 2, in
from script import init_scripts
File "/home/VideoCrawlerEngine-master/script/init.py", line 5, in
from utils import utility_package, split_name_version
File "/home/VideoCrawlerEngine-master/utils.py", line 12, in
from debugger import dbg
File "/home/VideoCrawlerEngine-master/debugger.py", line 3, in
from contextvars import ContextVar
ModuleNotFoundError: No module named 'contextvars'

contextvars包安装错误，你可以用匹配手动安装一下，使用pip install contextvars, 或者使用pip install contextvars=XXX，其中的XXX代表包的版本，可以从requirements.txt中看到。
