我正在安装MongoDB，我需要mongoimport。我已经从源MongoDB from source安装了MongoDB本身。我仍然需要 mongoimport ，它是 mongo-tools mongo-tools github的一部分。上面写了一些说明，我已经克隆了仓库，并进入了仓库（ / ssd / [MYNAME] / mongoinstall / mongo-tools ）并运行了
. ./set_gopath.sh回购的自述文件指出可以运行go env，但该文件不存在。
尽管我不觉得命令做了什么
go build -o bin/mongoimport mongoimport/main/mongoimport.go
不变。
我也已经从源代码安装了GO。

返回以下错误：

我尝试过

但它惊呼：

如何使mongoimport正常工作？
答案 0 :(得分：1)
在尝试在Mac系统上编译mongotools时遇到了同样的错误。就我而言，问题是set_gopath.sh（对于mongotools版本3.6.5）与我使用的shell（fish）不兼容。该脚本会导出GOPATH环境变量，但是一旦回到fish环境中，它似乎就不会保留其适当的变量。
我尝试将bash运行在持久的bash shell中，先运行set_gopath.sh，然后再运行go build命令，但是结果是相同的问题。
我发现一个成功的解决方法是修改set_gopath.sh，最后添加go build命令。运行set_gopath.sh，然后设置环境并成功运行go命令。
