在 macOS (10.14.6) 上使用“shirou/gopsutil”Go 包作为供应商包失败

Question

我试图在influx/telegraf本地构建并使用go mod vendor命令供应所有包。然而，有趣的是，构建失败后出现以下错误：# github.com/shirou/gopsutil/hostvendor/github.com/shirou/gopsutil/host/host_darwin_cgo.go:9:11: fatal error: 'include/smc.c' file not found #include "include/smc.c"          ^~~~~~~~~~~~~~~重现步骤（设置 GOPATH 变量后）：# Fetch the project, e.g. influx/telegrafgo get -d github.com/influxdata/telegraf# CD into the projectcd $GOPATH/src/influxdata/telegraf# Checkout v1.14.5 (the current latest version)git checkout v1.14.5# Fetch the modules under vendor/ directorygo mod vendor# Then modify the Makefile as follows:# 1. Remove the `deps` target and its reference in the `all` target; it is not needed anymore, as we fetched all modules.# 2. Add the `-mod vendor` flag everywhere `go build`, `go install`, or `go test` is called. This is necessary since Telegraf v1.14.5 is still on version 1.12 of Go, which requires this flag to use the modules under `vendor/` directory.# Finally, build the project and you should get the error abovemake

事实证明，这个错误是由一个众所周知的问题引起的，即go mod vendor修剪非包目录，从而导致包含文件的host/include文件夹被修剪：shirou/gopsutilsmc.c

shirou/gopsutil已经报告了此问题的影响：

显然没有简单的解决方案，但目前的解决方法是将丢失的目录手动复制到vendor/github.com/shirou/gopsutil. 在我的情况下，我复制freebsd_headers并include从$GOPATH/pkg/mod/github.com/shirou/gopsutil/hostto$GOPATH/src/github.com/influxdata/telegraf/vendor/github.com/shirou/gopsutil并且它有效。

我希望你觉得这有帮助。

您可以进行手动复制。我发现下面的解决方法也很有帮助。

运行这些命令

go get github.com/shirou/gopsutil
go mod vendor
