macos - 当构建参数包含`-gcflags“all = -N -l”并在MacOS中导入net/http时，构建失败

Question

当我尝试调试时，go build参数包含-gcflags "all=-N -l"，并且我导入net/http，那么构建将失败。
我尝试使用brew重新安装golang，但无法正常工作。
并尝试在卸载后使用offical installation，不起作用。
而且我尝试sudo mv /Library/Developer/CommandLineTools CommandLineTools.old && xcode-select --install，不起作用。
在JimB的建议下，我尝试了go env -w CGO_ENABLED=0，以便可以正确构建。
有什么建议么？
构建失败消息:

我发现一些类似的问题: Go: build error when compiling unit tests (I'm trying to mock influxdb types)
但是我没有使用相对进口

Answer 1

go env -w CGO_ENABLED=0可以暂时解决此问题。

升级MacOS和XCode之后，此问题不再发生。

现在我的版本:

MacOS 10.15.3
XCode 11.3.1(11C504)
