在安裝完 VS Code 后開始安裝 go 的插件發現有如下錯誤

wohu@wohu:~/GoCode/src$ go install github.com/nsf/gocode
# github.com/nsf/gocode
github.com/nsf/gocode/package_ibin.go:99: r.declReader.Reset undefined (type bytes.Reader has no field or method Reset)
github.com/nsf/gocode/package_ibin.go:148: undefined: io.SeekCurrent
github.com/nsf/gocode/package_ibin.go:152: undefined: io.SeekCurrent
github.com/nsf/gocode/package_ibin.go:214: r.declReader.Reset undefined (type bytes.Reader has no field or method Reset)

查閱相關資料后發現是由于使用

sudo apt-get insall golang-go

命令安裝的 go 版本為 go 1.6 , 版本過低導致。 所以需要卸載這個版本再重新安裝更新的版本。

wohu@wohu:~/GoCode/src$ sudo apt-get remove golang-go
