Installing package Golearn
问题
我正在尝试安装Golearn包，按照这些说明进行操作。
在终端中运行以下命令：
go get -t -u -v github.com/sjwhitworth/golearn
然后我尝试运行（按照要求）：
cd $GOPATH/src/github.com/sjwhitworth/golearn
然而，bash找不到该目录。我应该怎么办？（我正在使用Linux）
英文:
I'm try to install the package Golearn, following these instructions.
After running in the terminal
go get -t -u -v github.com/sjwhitworth/golearn
I tried to run (as required):
cd $GOPATH/src/github.com/sjwhitworth/golearn
However bash doesn't find this directory. What should I do?
(I'm using linux)

我做了以下操作并成功了：
go get -t -u -v github.com/sjwhitworth/golearn
go: 正在下载 github.com/sjwhitworth/golearn v0.0.0-20221228163002-74ae077eafb2
go: 已添加 github.com/sjwhitworth/golearn v0.0.0-20221228163002-74ae077eafb
go env GOPATH
/Users/<my_username>/go
cd /Users/<my_username>/go/pkg/mod/github.com/sjwhitworth/golearn@v0.0.0-20221228163002-74ae077eafb2
sudo go get -t -u -v ./...
英文:
I did the following and worked:
go get -t -u -v github.com/sjwhitworth/golearn
> go: downloading github.com/sjwhitworth/golearn v0.0.0-20221228163002-74ae077eafb2

golearn的说明可能有些过时，你可以按照我的步骤进行操作：
- 进入一个空文件夹，比如
/home/your/code/my_golearn，下面的所有命令都应该在这个文件夹中运行。 - 运行
go mod init my_golearn来初始化一个Go项目，你将得到一个go.mod文件。 - 创建一个
main.go文件，并将代码填入其中，代码可以从https://github.com/sjwhitworth/golearn#getting-started获取。 - 运行
go get github.com/sjwhitworth/golearn。 - 运行
go mod download来获取所有的依赖项。 - 运行
go get github.com/sjwhitworth/golearn/knn，这可能有些奇怪，但如果缺少这个命令，它将无法正常工作。我认为可能是golearn的开发者在使用go mod时出现了一些错误。 - 运行
wget https://raw.githubusercontent.com/sjwhitworth/golearn/master/examples/datasets/iris.csv -P datasets来获取所需的数据集。 - 运行
go run ./main.go，你将得到与https://github.com/sjwhitworth/golearn#getting-started相同的结果。
如果你对如何在现代的Go项目中安装依赖项不熟悉，最好阅读https://go.dev/blog/using-go-modules。
英文:
The instruction of golearn maybe some outdated, you can follow my process:
cdinto a empty folder, like/home/your/code/my_golearn, all commands below should be run at this floder- run
go mod init my_golearnto init a go project, you will get ago.modfile - create a
main.gofile and fill it with code from https://github.com/sjwhitworth/golearn#getting-started - run
go get github.com/sjwhitworth/golearn - run
go mod downloadto get all dependencies - run
go get github.com/sjwhitworth/golearn/knn, it's strange, but it doesn't work if this command miss, I think maybe the developer of golearn has some misuse of go mod - run
wget https://raw.githubusercontent.com/sjwhitworth/golearn/master/examples/datasets/iris.csv -P datasetsto get dataset you need - run
go run ./main.go, you will get result same as https://github.com/sjwhitworth/golearn#getting-started
