colab

如何在Google Colab上运行Golang。

    1. 运行第一个代码单元格，使用 Python 运行时。

 

    1. 刷新页面以使用 Go 内核（gophernotes）。

 

    通过运行下面的 Golang 代码单元格测试一切是否正常。
!add-apt-repository ppa:longsleep/golang-backports -y
!apt update
!apt install golang-go
%env GOPATH=/root/go
!go get -u github.com/gopherdata/gophernotes
!cp ~/go/bin/gophernotes /usr/bin/
!mkdir /usr/local/share/jupyter/kernels/gophernotes
!cp ~/go/src/github.com/gopherdata/gophernotes/kernel/* \
       /usr/local/share/jupyter/kernels/gophernotes

上面的部分不工作。
这个脚本安装失败。
!cp ~/go/src/github.com/gopherdata/gophernotes/kernel/*
在这个地方出错。

Screenshot_20210421-193609_kindlephoto-277179743.png

然而，似乎没有大错误。感觉已经达到了一个好的程度。
可能是在指定目录时出现了错误，在GitHub上进行了程序版本更新。需要找出从GitHub复制到Colab本地的核心（有点复杂）所在的位置。

使用以下脚本。

在前一个部分的脚本中，安装会出现错误。
很可能是因为~/go/src/github.com/路径不存在。
请尝试以下脚本进行测试。安装大约需要2分钟。
安装完成后，将重新加载页面。

参考。

测试Go语言

如果在上面的部分，安装Go语言的内核没有出错，那么请在浏览器中重新加载页面，切换到Go语言的内核并使用常见的Go语言语法来测试Go程序。

import "fmt"

fmt.Println("Hello, Gianni!")

for i := 1; i < 10; i++ {
  print(i)
}

检查当前的初始状态，是指环境变量吗？

$go env

GOENV="/root/.config/go/env"

虽然很重要，但在代码单元格中需要使用美元符号$来执行bash命令。

举个例子，

$go get github.com/kkdai/youtube/v2

$go env GOPATH

$dir /root/go/

$pwd

对于Python内核，我记得有”!”、”%”、”%%”和”%%bash”等选项。

### Alternatively: Using "jupyter kernel install <kernel-dir>"
# ! mkdir -p ./gophernotes
# ! cp $REPO_LOCAL/kernel ./gophernotes
# ! jupyter kernel install ./gophernotes

请注意以下事项限制：
https://github.com/gopherdata/gophernotes#限制

如果您想了解其他内核，请尝试查询有关jupyter内核的信息。
