Go: Run External Python script
问题
我尝试按照Go文档的指示调用一个Python脚本，该脚本只输出"Hello"，但到目前为止都失败了。
exec.Command("script.py")
或者我还尝试调用一个简单地调用Python脚本的shell脚本，但也失败了：
exec.Command("job.sh")
有什么想法如何实现这个？
编辑
我按照评论中的建议解决了问题，并在exec.Command()中添加了完整路径。
英文:
I have tried following the Go Docs in order to call a python script which just outputs "Hello" from GO, but have failed until now.
exec.Command("script.py")
or I've also tried calling a shell script which simply calls the python script, but also failed:
exec.Command("job.sh")
Any ideas how would I achieve this?
EDIT
I solved following the suggestion in the comments and adding the full path to exec.Command().

exec.Command("script.py").Run()
exec.Command("job.sh").Run()
你可以在“如何在Golang中执行简单的Windows DOS命令？”中看到它的用法（适用于Windows，但对Unix也适用）
c := exec.Command("job.sh")
if err := c.Run(); err != nil {
fmt.Println("错误：", err)
}
或者，使用Output()，就像在“在Go中执行shell命令”中所示：
cmd := exec.Command("job.sh")
out, err := cmd.Output()
if err != nil {
println(err.Error())
return
}
fmt.Println(string(out))
英文:
Did you try adding Run() or Output(), as in:
exec.Command("script.py").Run()
exec.Command("job.sh").Run()
You can see it used in "How to execute a simple Windows DOS command in Golang?" (for Windows, but the same idea applies for Unix)
c := exec.Command("job.sh")
if err := c.Run(); err != nil {
fmt.Println("Error: ", err)
}
Or, with Output() as in "Exec a shell command in Go":
cmd := exec.Command("job.sh")
out, err := cmd.Output()
if err != nil {
println(err.Error())
return
}
fmt.Println(string(out))

首先，不要忘记将你的Python脚本设置为可执行（设置权限并在开头添加#!/usr/local/bin/python）。
之后，你可以运行类似于以下的代码（注意它会报告错误和标准输出）。
package main
import (
"log"
"os"
"os/exec"
)
func main() {
cmd := exec.Command("script.py")
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
log.Println(cmd.Run())
}
英文:
First of all do not forget to make your python script executable (permissions and #!/usr/local/bin/python at the beginning).
After this you can just run something similar to this (notice that it will report you errors and standard output).
package main
import (
"log"
"os"
"os/exec"
)
func main() {
cmd := exec.Command("script.py")
cmd.Stdout = os.Stdout
cmd.Stderr = os.Stderr
log.Println(cmd.Run())
}

以下是在Windows 10上适用的代码：
python := path.Clean(strings.Join([]string{os.Getenv("userprofile"), "Anaconda3", "python.exe"}, "/"))
script := "my_script.py"
cmd := exec.Command("cmd", python, script)
out, err := cmd.Output()
fmt.Println(string(out))
if err != nil {
log.Fatal(err)
}
请注意，这是一段使用Go语言编写的代码，用于在Windows 10上运行Python脚本。它使用os.Getenv函数获取用户配置文件路径，并将其与Anaconda3和python.exe的路径组合起来。然后，它使用exec.Command函数创建一个命令，该命令在cmd中执行Python脚本。最后，它通过cmd.Output函数获取命令的输出，并将其打印出来。如果发生错误，它将使用log.Fatal函数记录错误信息。
英文:
Below worked for me on Windows 10
python := path.Clean(strings.Join([]string{os.Getenv("userprofile"), "Anaconda3", "python.exe"}, "/"))
script := "my_script.py"
cmd := exec.Command("cmd", python, script)
out, err := cmd.Output()
fmt.Println(string(out))
if err != nil {
log.Fatal(err)
}
