Then i tried executing the following command to solve the problem: root@test-server:docker exec -i -t pupy-dcae /bin/bash root@pupy:/#cd pupy root@pupy:/#pip install -e external/pykcp

Hopefully the next release of docker will fix this problem. btw, the current wiki is too simple and Outdated, in the actual deployment process, whether it is docker or direct installation, there are a variety of problems, can you improve the FAQ for various questions on the wiki ?

Can you check the content of the folder at the git-root://pupy/external/pykcp/kcp ?

First I run "pip install -e external/pykcp" in the host directory, then I run "/pupyws/bin/pupysh-update" in the host, but not solve problem,and finally run "pip install -e external/pykcp" in the docker, so now I'm not sure if pip/external/pykcp/kcp is the original content of the directory. The directory I am checking is as follows.
