<p class="maodian"><a name="_label1"></a></p><h2>解决</h2>
<p>1、更新dlv版本</p>
<div class="jb51code"><pre class="brush:go;">go get -u github.com/go-delve/delve/cmd/dlv@latest
go install github.com/go-delve/delve/cmd/dlv@latest</pre></div>
<p>2、查看delve版本</p>
<div class="jb51code"><pre class="brush:go;">$ dlv version
Delve Debugger
Version: 1.25.2
Build: $Id: af3df277866d7175e816eab14e56611053d4cdea $
</pre></div>
<p>3、设置goland 打开 <code>Hele->Edit Customer Properties</code> 添加<code>dlv.path=GOPATH/bin/dlv.exe</code></p>
<div class="jb51code"><pre class="brush:plain;"># custom GoLand properties (expand/override 'bin\idea.properties')
dlv.path=D:/GoProject/bin/dlv.exe</pre></div>
<p>4、重启goland</p>
<p class="maodian"><a name="_label2"></a></p><h2>补充</h2>
<p><strong>delve有三种调试模式：</strong></p>
<ul><li>dlv attach pid：对正在运行的进程直接进行调试（pid 为进程id）</li><li>dlv debug：编译源文件并开始调试，main 函数位于同一目录，或者指定完整的 main 函数路径</li><li>dlv exec filename：从二进制文件启动调试</li></ul>
