What version of shadowsocks-libev are you using?

3.1.0

What operating system are you using?

mac os 10.13

What did you do?

I install shadowsocks-libev and simple-obfs by brew.

What did you expect to see?

When I use "brew services start shadowsocks-libev" with obfs plugin, chrome can use 127.0.0.1:1080 for socks5 proxy.
我配置了obfs混淆，使用“brew services start shadowsocks-libev”启动后，socks5代理能正常工作。

What did you see instead?

Actually, when I use "brew services start shadowsocks-libev", the echo shows success but the proxy is not work. Well now, I use "/usr/local/opt/shadowsocks-libev/bin/ss-local -c /usr/local/etc/shadowsocks-libev.json", there is no port bind error, and the socks5 proxy is working. I am puzzled. And I checked the file "/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist". There is nothing wrong. I use “brew doctor” for checking, and there is no errors too.
What should I do?
It seems the "brew services start shadowsocks-libev" with plugin obfs didn't work but the command "/usr/local/opt/shadowsocks-libev/bin/ss-local -c /usr/local/etc/shadowsocks-libev.json" works.
By the way, if I clear the "plugin" and "plugin_opts" in the shadowsocks-libev.json, "brew services start shadowsocks-libev" worked and socks5 proxy is working .
实际上，配置了obfs混淆，使用“brew services start shadowsocks-libev”启动后，显示的是服务启动成功，但是代理实际没用工作。同时，我再用命令行启动"/usr/local/opt/shadowsocks-libev/bin/ss-local -c /usr/local/etc/shadowsocks-libev.json"启动代理，居然成功，而且没有端口绑定报错。我检查过"~/Library/LaunchAgents/homebrew.mxcl.shadowsocks-libev.plist"，没有错误。我用“brew doctor”检测，brew也没有报错。
似乎，如果配置了plugin obfs，"brew services start shadowsocks-libev" 就没法启动服务，敲命令行用“ss-local -c xxx.json”又可以启动服务。
如果，我删除了配置文件中的 "plugin"和"plugin_opts”，"brew services start shadowsocks-libev" 又正常了。

What is your config in detail (with all sensitive info masked)?

{
"server":"vps ip",
"server_port":8153,
"local_port":1080,
"password":"password",
"timeout":600,
"method":"chacha20-ietf-poly1305",
"plugin":"obfs-local",
"plugin_opts":"obfs=tls;obfs-host=cloudfront.net"
}

Try absolute path of the obfs-plugin in this case.
