我访问了Plotinum项目站点，以便在 Go 中生成绘图，但我无法在 Ubuntu 12.04 LTS 上安装该软件。我能够顺利安装 svgo 和 draw2d，但是 plot、plotter 和 plotutil 出现如下错误:

go version 的输出是，

$ go version
go version go1

go env 的输出是，

$ go env
GOROOT="/usr/lib/go"
GOBIN=""
GOARCH="amd64"
GOCHAR="6"
GOOS="linux"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOTOOLDIR="/usr/lib/go/pkg/tool/linux_amd64"
GOGCCFLAGS="-g -O2 -fPIC -m64 -pthread"
CGO_ENABLED="1"

谢谢!

最佳答案

例如，

$ go version
go version devel +70af843fed44 Sat Apr 19 09:55:09 2014 +0200 linux/amd64

$ go env
GOARCH="amd64"
GOBIN=""
GOCHAR="6"
GOEXE=""
GOHOSTARCH="amd64"
GOHOSTOS="linux"
GOOS="linux"
GOPATH="/home/peter/gopath
GORACE=""
GOROOT="/home/peter/go"
GOTOOLDIR="/home/peter/go/pkg/tool/linux_amd64"
CC="gcc"
GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
CXX="g++"
CGO_ENABLED="1"

$ uname -a

go version 和 go env 的输出是什么？

关于plot - 安装 Plotinum for Go，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23259764/
