英文:
Trying to exec python in golang using exec.Command(
问题
func execPython(fPath, colName, srv string) (){
fmt.Println("在execPython函数内")
cmd := "python rfsvmchurn.py"
arg0 := "-fp " + fPath
arg1 := "-srv " + srv
arg2 := "-col " + colName
if err := exec.Command(cmd, arg0, arg1, arg2).Run(); err != nil {
fmt.Println("Python执行错误:", err)
}
}
出现错误
Python执行错误: exec: "python rfsvmchurn.py": 在$PATH中找不到可执行文件
英文:
func execPython(fPath, colName, srv string) (){fmt.Println("Inside execPython")cmd:= "python rfsvmchurn.py"arg0 := "-fp " + fPatharg1 := "-srv " + srvarg2 := "-col " + colNameif err := exec.Command(cmd, arg0, arg1, arg2).Run(); err != nil {fmt.Println("Python Execution Error :",err)}
}
getting error
Python Execution Error : exec: "python rfsvmchurn.py": executable file not found in $PATH

你的问题可能是你将标志和它们的参数作为一个字符串传递。你应该这样做：
func execPython(fPath, colName, srv string) {fmt.Println("Inside execPython")arg0 := "-fp " + fPatharg1 := "-srv " + srvarg2 := "-col " + colNamecmd := exec.Command("python", "rfsvmchurn.py", "-fp", fPath, "-srv", srv, "-col", colName)if err := cmd.Run(); err != nil {fmt.Println("Python Execution Error:", err)}}
请注意，我已经将代码翻译成了中文。
英文:
Your issue is probably that you're passing flags and their arguments as a single string. You should instead do:
func execPython(fPath, colName, srv string) (){fmt.Println("Inside execPython")arg0 := "-fp " + fPatharg1 := "-srv " + srvarg2 := "-col " + colNamecmd := exec.Command("python", "rfsvmchurn.py", "-fp", fPath, "-srv", srv, "-col", colName)if err := cmd.Run(); err != nil {fmt.Println("Python Execution Error :",err)}}
