找不到 discord bot heroku 的路径

Question

我已经向 Heroku 部署了一个 discord.py 重写机器人，并且我遵循了所有部署步骤并且成功了。我试图将我的代码调整为具有可更改的前缀，但我需要使用 JSON 文件夹才能正常工作，所以我这样做并将其添加到 PATH 并将其添加到我的 GitHub 代表并且一切似乎工作，它已上传并部署，但机器人现在无法工作，因为它找不到前缀。错误显然是找不到 JSON 文件的路径。

我的路径获取码:

async def get_prefix(client, message):
    with open('storage\pp.json', 'r') as f:
        prefixes = json.load(f)

    try:
        prs = prefixes[str(message.guild.id)]
    except KeyError:
        prs = "p."
    return prs

使用“Heroku logs --tail”的 Heroku 错误：

路径正确，在我的电脑上运行。它只是在 Heroku 上不起作用？ Linux有问题吗？

Answer 1

所以很明显，当你将机器人推送到 Heroku 时，它会将机器人放在 Linux 服务器上，也就是 Linux 机器，它不理解与 windows 相同的路径：

所以应该是：

async def get_prefix(client, message):
    with open('storage\pp.json', 'r') as f: #  It should be 'storage//pp.json'
        prefixes = json.load(f)

    try:
        prs = prefixes[str(message.guild.id)]
    except KeyError:
        prs = "p."
    return prs

所以基本上你的路径应该是正斜杠 2 个斜杠
