运行时错误：invalid memory address or nil pointer dereference

[callmepeanut]

使用如下命令安装的： go get github.com/v2ray/v2ray-core go build github.com/v2ray/v2ray-core/release/server

错误信息如下： [ec2-user@ip ~]$ ./server --config="/home/ec2-user/vpoint_vmess_freedom.json" panic: runtime error: invalid memory address or nil pointer dereference [signal 0xb code=0x1 addr=0x0 pc=0x47b9cf]

遇到同样的问题，应该和callmepeanut是同一个版本，我的情况如下

OS: ubuntu server 14.04 64bit v2Ray 版本: 不知道怎样取得版本可功能，2015/10/10 10:30AM左右执行 go get github.com/v2ray/v2ray-core 取的代码。应该最新的，在项目首页copy sha得到的：b115df56c08aff26b80c5e1eb8134a594d84670b golang 版本:1.5.1 问题描述：把json文件复制到 GOPATH/bin/config，vpoint_vmess_freedom.json内容如下

"port": 27183, "inbound": { "protocol": "vmess", "settings": { "clients": [ {"id": "ec12cd1a-6e37-11e5-9d70-feff819cdc9f"} ], "udp": false } }, "outbound": { "protocol": "freedom", "settings": {} } }

执行./server --config="/root/work/bin/config/vpoint_vmess_freedom.json" 会报错，日志如下

已解决，json配置文件加上“log”字段即可。 参照文件：https://github.com/v2ray/v2ray-core/blob/master/release/config/vpoint_vmess_freedom.json

本质上这是一个 golang 的 bug，我已经向他们提 issue 了：https://github.com/golang/go/issues/12897
