shadowsocks AttributeError: module 'collections' has no attribute 'MutableMapping'

I was trying to set up an VPN on Vultr via Shadowsocks, and trying to run Shadowsocks service manually. I tried below in my bash:

sudo ssserver -c /etc/shadowsocks.json

It has error: AttributeError: module 'collections' has no attribute 'MutableMapping'

I am using Python 3.10.12 version

below is the ERROR:

    root@vpn-test:~# sudo ssserver -c /etc/shadowsocks.json

Solution

  • Version 2.8.2 is very old, it was good till python 3.9.

    Please use the latest shadowsocks v5.3.3
