在linux上可以用下面操作进行
while read requirement; do sudo pip install $requirement; done < requirement.txt
在windows上写个脚本
import sys
from pip._internal import main as pip_main
def install(package):
pip_main(['--default-timeout=1000','install','-U', package])
if __name__=='__main__':
with open(sys.argv[1],'rb') as f:
for line in f:
install(line)
注意代码命令里面路径要对应自己文件路径。
