Platformio build error

Platformio cannot compile.
It is the same even if you install it from the beginning after deleting the whole thing.
Cannot compile after installing new project. The code is basic code like below.

#include <Arduino.h>

void setup() {
Serial. begin(115200);

void loop() {
Serial. println(“ssss”);

An error occurs because there is no pc name

Well I don’t see your compile errors, but you do need to install the terminal.
