HTTPserver python Hello world系统找不到指定的路径

Question

from http.server import HTTPServer, BaseHTTPRequestHandler 

class HelloHandler(BaseHTTPRequestHandler):
def do_GET(self):
    # First, send a 200 OK response.
    self.send_response(200)

    # Then send headers.
    self.send_header('Content-type', 'text/plain; charset=utf-8')
    self.end_headers()

    # Now, write the response body.
    self.wfile.write("Hello, World!\n".encode())

if __name__ == '__main__':
server_address = ('', 8000)  # Serve on all addresses, port 8000.
httpd = HTTPServer(server_address, HelloHandler)
httpd.serve_forever()

上面的代码给出“系统找不到指定的路径”。当我运行它时。 错误是什么意思？
