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

问题描述

我想用去安装json2csv，去获取github.com/jehiah/json2csv 但我收到这个错误：

  package github.com/jehiah/json2csv：无法下载，$ GOPATH未设置。有关更多详细信息，请参阅：go help go path 
  

有关如何在MacOS上解决此问题的任何帮助？ p>

解决方案

[更新：自1.8起， GOPATH 默认为 $ HOME / go ，但如果您想了解 GOPATH 布局，自定义等等，您仍然可以发现它有用。]

官方Go网站讨论GOPATH以及如何铺设出工作区目录。

export GOPATH =$ HOME / your-workspace-dir / - 在你的shell中运行它，然后将它添加到〜/ .bashrc 或等价物中，以便将来为你设置。 Go将在 src / ， bin / 和 pkg / ，那里的子目录。你需要把你自己的包放在 $ GOPATH / src 之下的某个地方，比如 $ GOPATH / src / github.com / myusername / 如果你想发布到GitHub。你也可以在你的 .bashrc 中使用 export PATH = $ PATH：$ GOPATH / bin ，这样你就可以运行在 $ GOPATH 下编译的程序。

或者，通过Rob Pike ，你也可以设置 CDPATH ，所以它快于 cd 将bash包装在bash中： export CDPATH =。：$ GOPATH / src / github.com：$ GOPATH / src / golang.org / x 表示您可以输入 cd net / html 而不是 cd $ GOPATH / src / golang.org / x / net / html 。

Keith Rarick您可以设置笔记 GOPATH = $ HOME 将Go的 src / ， pkg / 和 bin / 目录下的homedir。这可能很好（例如，您的路径中可能已经有 $ HOME / bin ），但当然有些人会使用多个工作区等。

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

Any help on how to fix this on MacOS?

解决方案

[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.]

The official Go site discusses GOPATH and how to lay out a workspace directory.

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.

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 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.
