proxy=127.0.0.1:808 is to set the network proxy.

Change 127.0.0.1 to the IP address of your own proxy network, 808 is the port, and the setting is consistent with the port of CCProxy.

If you use the above statement, the error is as follows:

ImportError: No module named pkg_resources

You can use the following statement to install ：

python -m pip --proxy=127.0.0.1:808 install

2. Use apt-get to install the required packages: sudo apt- get -o Acquire::http::proxy="http://127.0.0.1:808/" install package name

Acquire::http::proxy="http: //127.0.0.1:808/” To set up the network proxy
