Cog文件无法定位。同一目录中的json文件

Question

正如标题所示，我为不和谐机器人创建的齿轮文件无法读取/写入保存在同一文件夹中的. json文件。我尝试过手动指定文件路径，将. json文件移动到主bot文件的根文件夹，重命名. json文件，但都无济于事。移动. json文件可以阻止bot抛出丢失的文件错误，但它会使cog文件不再同时工作，这实际上造成了两个没有解决方案的问题。

cog文件如下所示

import discord
import logging
import json
import os
from discord.ext import commands


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

#Sets default prefix for server on first join    
    @commands.Cog.listener()
    async def on_guild_join(guild):
        with open('prefixes.json', 'r') as f:
            prefixes = json.load(f)
        prefixes[str(guild.id)] = '.'
        with open ('prefixes.json', 'w') as f:
            json.dump(prefixes, f, indent = 4)

#Command for assigning a new prefix
@commands.command()
@commands.has_role("admin" == True)
async def change_prefix(ctx, prefix):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)
    prefixes[str(ctx.guild.id)] = prefix
    with open ('prefixes.json', 'w') as f:
        json.dump(prefixes, f, indent = 4)
    await ctx.send(f'Prefix changed to: {prefix}')

#Placeholder Prefix Command
def get_prefix(client, message):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)
    return prefixes[str(message.guild.id)]
client = commands.Bot(command_prefix = get_prefix)

#Removes the stored prefix when bot is kicked
async def on_guild_remove(guild):
    with open('prefixes.json', 'r') as f:
        prefixes = json.load(f)
    prefixes.pop(str(guild.id))
    with open ('prefixes.json', 'w') as f:
        json.dump(prefixes, f, indent= 4)


#Connects Cog to bot
def setup(client):
    client.add_cog(Prefixes(client))

如果有帮助的话，主文件如下

from cogs.Prefix_changer import Prefixes, get_prefix
import discord
import logging
import os
import discord.ext.commands.errors
from discord.ext import commands


client = commands.Bot(command_prefix = get_prefix)

#Error messages
@client.event
async def on_command_error(ctx, error):
    if isinstance(error, commands.MissingRequiredArgument):
        await ctx.send('Please specify a valid command extension.')
    elif isinstance(error, commands.CommandNotFound):
        await ctx.send('Command is not valid.')
    elif isinstance(error, commands.ExtensionNotLoaded):
        await ctx.send('Extension was not loaded.')
    elif isinstance(error, commands.ExtensionNotFound):
        await ctx.send('Extension could not be found.')
    elif isinstance(error, commands.ExtensionAlreadyLoaded):
        await ctx.send('Extension has already been loaded.')

#Loading Cogs
@client.command()
async def load(ctx, extension):
    client.load_extension(f'cogs.[extension]')
#unloading Cogs
@client.command()
async def unload(ctx, extension):
    client.unload_extension(f'cogs.[extension]')
#Searches the primary directory for Cogs folder
for filename in os.listdir('./cogs'):
    if filename.endswith('.py'):
        client.load_extension(f'cogs.{filename[:-3]}')


client.run('token removed')

在使用诸如“.”之类的前缀之前，bot运行正常或以“$”为例。一旦使用前缀，它将抛出以下错误：

分/文件/Py括号bot/Main。py“忽略on_消息回溯中的异常（最近一次调用）：File”/Library/Frameworks/Python。framework/Versions/3.9/lib/python3。9/站点包/discord/客户端。py“，第343行，在_run_event wait-coro（*args，**kwargs）文件“/库/框架/Python中。framework/Versions/3.9/lib/python3。9/站点包/discord/ext/commands/bot。py”，第979行，在on_message wait self.process_命令（消息）文件“/Library/Frameworks/Python中。framework/Versions/3.9/lib/python3。9/站点包/discord/ext/commands/bot。py”，第975行，进程中命令ctx=wait self.get_上下文（消息）文件“/Library/Frameworks/Python。framework/Versions/3.9/lib/python3。9/站点包/discord/ext/commands/bot。py”，第886行，在get_context prefix=wait self.get_prefix（消息）文件“/Library/Frameworks/Python中。framework/Versions/3.9/lib/python3。9/站点包/discord/ext/commands/bot。py”，第831行，在get_prefix ret=wait discord.utils.maybe_coroutine（前缀，self，message）文件“/Library/Frameworks/Python中。framework/Versions/3.9/lib/python3。9/站点包/discord/utils。py“，第341行，在coroutine value=f（*args，**kwargs）文件“/Users/vincent/Documents/py-bracket-bot/cogs/Prefix\u-changer中。py“，第34行，在get_前缀中，open（'prefixes.json'，'r'）作为f:FileNotFoundError:[Errno 2]没有这样的文件或目录：'prefixes.json'

如果不是很明显的话，答案是肯定的。json文件是前缀。json。

将文件路径设置为包含cogs/修复了它。我不知道cog不会在所在的同一目录中查找。json文件。
