错误 could not launch process: EOF 解决

问题

当我兴致勃勃的开始 go 语言的 hello world 的时候, 蓦然回首

package main

import "fmt"

func main() {
    var i = 1
    fmt.Println("hello world ", i)
}

却发现, 竟然不能 debug....

could not launch process: EOF
Process exiting with code: 1

• 系统: mac OSX 10.13.3/4/5
• IDE :IntelliJ IDEA
  仔细 google 了一番,貌似是 CommandLineTools 更新后的问题.

解决方案

Solution 1(推荐)

感谢Nob东瓜提供,用新版的 dlv 替换 idea 提供的旧版的(旧版dlv bug导致的，编译最新的dlv替换idea自带的即可).

1. dlv 项目地址https://github.com/derekparker/delve
   2.安装最新的 dlv.

go get -v  -u github.com/derekparker/delve/cmd/dlv
cd $GOPATH/src/github.com/derekparker/delve
make install

完成后

➜  delve git:(master) make install
scripts/gencert.sh || (echo "An error occurred when generating and installing a new certificate"; exit 1)
go install -ldflags="-s -X main.Build=9a216211d3461ab031f822c012bc27cab9758da0" github.com/derekparker/delve/cmd/dlv
codesign -s "dlv-cert"  /usr/local/Cellar/go/1.10.3/libexec/bin/dlv

3. 替换文件

cd '/Users/{user}/Library/Application Support/IntelliJIdea2017.2/intellij-go/lib/dlv/mac'
mv dlv dlv_back
ln -s $GOROOT/bin/dlv dlv

$GOROOT/bin/dlv 指向的文件就是/usr/local/Cellar/go/1.10.3/libexec/bin/dlv

如果你用的 Goland 同样的道理

cd /Applications/GoLand.app/Contents/plugins/intellij-go-plugin/lib/dlv/mac
mv dlv dlv_back
ln -s $GOROOT/bin/dlv dlv

ps:貌似有些 goland 的路径在/Applications/GoLand.app/Contents/plugins/go/lib/dlv/mac,自己试下就可以啦

哦了

Solution 2

1. 删除系统现有的CommandLineTools

sudo rm -rf /Library/Developer/CommandLineTools

2. 访问 Apple 开发者工具 页面,用 apple ID 登录后,下载
   Command Line Tools (Mac OS 10.13) for Xcode 9.1 (Dec 6,2017)

3. 安装完成后. Everything OK!
