不一致py 1.5。0:名称错误：未定义名称“客户端”

Question

我对不和谐是新手。py并遵循有关齿轮的教程。我遵循了教程告诉我的所有内容，但在运行命令时出现了名称错误。

代码如下：

/机器人程序。py

import os
import discord
from discord.ext import commands

client = commands.Bot(command_prefix = '/')

@client.event
async def on_ready():
    await client.change_presence(status=discord.Status.online, activity=discord.Game('Under Development'))
    print('Bot Online')

@client.command()
async def load(ctx, extension):
    client.load_extension(f'cogs.{extension}')

@client.command()
async def unload(ctx, extension):
    client.unload_extension(f'cogs.{extension}')

for filename in os.listdir('./cogs'):
    if filename.endswith('.py'):
        client.load_extension(f'cogs.{filename[:-3]}')

client.run(os.environ['TOKEN'])

/齿轮。命令。py

import discord
from discord.ext import commands

class Commands(commands.Cog):
    def __init__(self, client):
        self.client = client

    @commands.command()
    async def ping(self, ctx):
        await ctx.send(f'Network Delay: **{round(client.latency * 1000)} ms**')

def setup(client):
    client.add_cog(Commands(client))

当我在discord消息框中键入/ping时，我得到了这个回溯

回溯（最近一次调用）：文件“C:\Users\bryan\source\repos\discord\u music\u bot\env\lib\site packages\discord\ext\commands\bot.py”，第903行，调用等待ctx。命令调用（ctx）文件“C:\Users\bryan\source\repos\discord\u music\u bot\env\lib\site packages\discord\ext\commands\core.py”，第859行，在调用等待注入（*ctx.args，**ctx.kwargs）文件“C:\Users\bryan\source\repos\discord\u music\u bot\env\lib\site packages\discord\ext\commands\core\core\core\core.py”，第94行，从exc discord中包装提升命令调用者错误（exc）。外部命令。错误。CommandInvokeError:命令引发异常：NameError:未定义名称“客户端”

多亏了@Brian，我终于纠正了错误。我编写客户端。延迟而不是self。客户延迟

async def ping(self, ctx):
        await ctx.send(f'Network Delay: **{round(self.client.latency * 1000)} ms**')
