这是由于国内网络的限制,下载速度慢而引起的。解决的办法有:
1.设置超时时间,比如:
pip --default-timeout=100 install dolphindb
2.更换pip下载源
可以在pip后面加上-i参数,指定pip源。比如换用清华大学pip源[https://pypi.tuna.tsinghua.ed...]如下:
pip install dolphindb -i https://pypi.tuna.tsinghua.edu.cn/simple/
我想根据DolphinDB api 的教程安装dolphindb包,但pip install时老提示Read timed out错误(详情如下所示),请问有什么办法?
