无法下载，未设置 $GOPATH [英] cannot download, $GOPATH not set

问题描述

我想使用 go get github.com/jehiah/json2csv 安装 json2csv，但我收到此错误:

I want to install json2csv using go get github.com/jehiah/json2csv but I receive this error:

package github.com/jehiah/json2csv: cannot download, $GOPATH not set. For more details see: go help go path

有关如何在 MacOS 上解决此问题的任何帮助?

Any help on how to fix this on MacOS?

推荐答案

[更新:从 Go 1.8 开始，GOPATH 默认为 $HOME/go，但你可以如果您想了解 GOPATH 布局、自定义它等，仍然会发现这很有用.]

[Update: as of Go 1.8, GOPATH defaults to $HOME/go, but you may still find this useful if you want to understand the GOPATH layout, customize it, etc.]

官方 Go 站点 讨论 GOPATH 以及如何布置工作区目录.

export GOPATH="$HOME/your-workspace-dir/" -- 在你的 shell 中运行它，然后将它添加到 ~/.bashrc 或等效的它会在未来为你设置.Go 将在 src/、bin/ 和 pkg/ 子目录下安装软件包.如果您想发布到 GitHub，您需要将自己的包放在 $GOPATH/src 下的某个位置，例如 $GOPATH/src/github.com/myusername/.您可能还需要 export PATH=$PATH:$GOPATH/bin 在您的 .bashrc 中，以便您可以在 $GOPATH 下运行已编译的程序.

export GOPATH="$HOME/your-workspace-dir/" -- run it in your shell, then add it to ~/.bashrc or equivalent so it will be set for you in the future. Go will install packages under src/, bin/, and pkg/, subdirectories there. You'll want to put your own packages somewhere under $GOPATH/src, like $GOPATH/src/github.com/myusername/ if you want to publish to GitHub. You'll also probably want export PATH=$PATH:$GOPATH/bin in your .bashrc so you can run compiled programs under $GOPATH.

可选地，通过 Rob Pike，您还可以设置 CDPATH所以 cd 在 bash 中打包目录会更快: export CDPATH=.:$GOPATH/src/github.com:$GOPATH/src/golang.org/x 意味着你可以只输入 cd net/html 而不是 cd $GOPATH/src/golang.org/x/net/html.

Optionally, via Rob Pike, you can also set CDPATH so it's faster to cd to package dirs in bash: export CDPATH=.:$GOPATH/src/github.com:$GOPATH/src/golang.org/x means you can just type cd net/html instead of cd $GOPATH/src/golang.org/x/net/html.

Keith Rarick notes 您可以将 GOPATH=$HOME 设置为将 Go 的 src/、pkg/ 和 bin/ 目录放在你的 homedir 下.这可能很好(例如，您的路径中可能已经有 $HOME/bin)，但当然有些人使用多个工作区等.

Keith Rarick notes you can set GOPATH=$HOME to put Go's src/, pkg/ and bin/ directories right under your homedir. That can be nice (for instance, you might already have $HOME/bin in your path) but of course some folks use multiple workspaces, etc.
