在更新到Go modules后，发现Emacs中的godef插件无法正常找到代码定义。本文将探讨这个问题的原因，并分享解决此问题的方法，帮助Go开发者在使用mod管理依赖时，依旧能高效地进行代码跳转。

#csutom go project path                                  
export GOPATH="/home/richard/project/project_go"
#go install path                                                  
export GOROOT=/usr/local/go
export PATH=$PATH:${GOPATH}/bin:${GOROOT}/bin
# Enable the go modules feature
export GO111MODULE=on
# Set the GOPROXY environment variable
export GOPROXY=https://goproxy.io

配置插件安装：
    go get -u -v github.com/nsf/gocode
    go get -u -v github.com/rogpeppe/godef
    go get -u -v golang.org/x/lint/golint

//执行go mod 会把依赖拷贝过来 godef 就能找到 定义
go mod vendor

emacs 配置
;;;custom go ide                                 
;;;代码释义用M-x godef-describe或者C-c C-d                  
;;;代码跳转用M-x godef-jump 或者C-c C-j
