无法调试 Go 代码:无法启动进程:解码偏移量 0x0 处的矮节信息:太短

Unable to debug Go code: could not launch process: decoding dwarf section info at offset 0x0: too short

我们正在尝试调试 Go 代码并收到此错误:

could not launch process: decoding dwarf section info at offset 0x0: too short

我们的设置:

我们尝试过的事情:

从命令行尝试 运行ning:

WITSC02X6385JGH:orderer sjain68$ /Users/sjain68/go/bin/dlv debug github.com/hyperledger/fabric/orderer --headless=true --listen=127.0.0.1:41305 --api-version=2 --log=true --

Exiting.
could not launch process: decoding dwarf section info at offset 0x0: too short

请注意,我们尝试调试的二进制文件确实被执行了。只是调试器没有启动。

我们从 this link 中尝试的另一件事:

WITSC02X6385JGH:orderer sjain68$ export GOFLAGS="-ldflags=-compressdwarf=false"; dlv debug
could not launch process: decoding dwarf section info at offset 0x0: too short

有人说 运行 GOCACHE=off go build ... 然后粘贴输出 here.

我们该如何解决这个问题?

我在更新 Go 后遇到了同样的问题。 从控制台更新 Delve 包有帮助:

go get -u github.com/go-delve/delve/cmd/dlv

对我们有用的解决方案是升级 Go 版本

$ go version
go version go1.13.3 darwin/amd64

所以 Go 1.11 是罪魁祸首。

确保您没有使用从构建中删除调试信息的标志,即 -ldflags="-s -w" 。
