python - 使用 "ptvsd"运行远程调试时出错

Question

我已经开始使用 Visual Studio 代码进行远程调试，但无法让它工作。远程和本地开发 PC 都运行 ptvsd 版本 4.1.3。远程机器有脚本:

import ptvsd
ptvsd.enable_attach()

#Enable the below line of code only if you want the application to wait untill the debugger has att$
#ptvsd.wait_for_attach()

import random


guesses_made = 0
name = input('Hello! What is your name?\n')
number = random.randint(1, 20)
print('Well, {0}, I am thinking of a number between 1 and 20.'.format(name))

while guesses_made < 6:
    guess = int(input('Take a guess: '))
    guesses_made += 1
    if guess < number:
        print('Your guess is too low.')
    if guess > number:
        print('Your guess is too high.')
    if guess == number:
        break
if guess == number:
    print('Good job, {0}! You guessed my number in {1} guesses!'.format(name, guesses_made))
else:
    print('Nope. The number I was thinking of was {0}'.format(number))

本地计算机是:

import ptvsd
ptvsd.enable_attach(address = ('192.34.98.197',3000))

#Enable the below line of code only if you want the application to wait untill the debugger has attached to it
#ptvsd.wait_for_attach()

import random

guesses_made = 0
name = input('Hello! What is your name?\n')
number = random.randint(1, 20)
print('Well, {0}, I am thinking of a number between 1 and 20.'.format(name))

while guesses_made < 6:
    guess = int(input('Take a guess: '))
    guesses_made += 1
    if guess < number:
        print('Your guess is too low.')
    if guess > number:
        print('Your guess is too high.')
    if guess == number:
        break
if guess == number:
    print('Good job, {0}! You guessed my number in {1} guesses!'.format(name, guesses_made))
else:
    print('Nope. The number I was thinking of was {0}'.format(number))

我已将条目添加到 launch.json 中:

{
    "name": "Attach (Remote Debug)",
    "type": "python",
    "request": "attach",
    "localRoot": "${workspaceRoot}",
    "remoteRoot": "/home/pi/testdebug/",
    "port": 3000,
    "secret": "my_secret",
    "host":"localhost"
},

这是我收到的错误:

如果有人有任何想法如何纠正此问题，请告诉我。

您的 launch.json 已过时，因为它是为旧调试器配置的。请参阅https://code.visualstudio.com/docs/python/debugging#_remote-debugging了解最新说明(例如 localRoot 和 remoteRoote 应位于 pathMappings 下)。
