libs = {
    
    "lxml","requests","pandas","numpy","you-get","opencv-python","pandas","fake_useragent","matplotlib","moviepy","lxml","wordcloud","jieba"}
try:
    for lib in libs:
        os.system(f"pip3 install -i https://pypi.doubanio.com/simple/ {lib}")
        print(lib+"下载成功")
except:
    print("下载失败")
