如何在Google Colaboratory上导入并使用PyWhatKit？

我想使用 pywhatkit 库自动从 Google Colab 在 WhatsApp 上发送消息。到目前为止，我已经尝试过这样做：

pip install pywhatkit

输出：

我还尝试查看 pip list 是否安装了它，它说它有：

pip list

输出：

....
....
pywhatkit     5.3
....
....

当我尝试导入时，它显示错误.

import pywhatkit

输出：

---------------------------------------------------------------------------
KeyError                                  Traceback (most recent call last)

--> 681             raise KeyError(key) from None
    682         return self.decodevalue(value)
    683 

KeyError: 'DISPLAY'

此问题的解决方法或解决方案是什么？

遇到的错误信息 "KeyError: 'DISPLAY'" 表明 PyWhatKit 无法找到系统上的显示服务器。这是因为 PyWhatKit 使用了依赖于图形用户界面 (GUI) 的库，例如 PyAutoGUI，而 Google Colab 是一个云端环境，默认情况下没有 GUI。

解决方案：

不幸的是，无法在 Google Colab 上直接使用 PyWhatKit 发送 WhatsApp 消息，因为它需要访问的本地显示器来控制浏览器。

替代方案：

可以考虑使用以下替代方案：

1. Twilio API： Twilio 提供了一个强大的 WhatsApp Business API，允许以编程方式发送和接收消息。可以在 Colab 中安装 Twilio Python 库，并使用的 Twilio 帐户凭据发送 WhatsApp 消息。

   • https://www.twilio.com/whatsapp

2. Vonage API： 与 Twilio 类似，Vonage 也提供了一个 WhatsApp API，可以将其集成到的 Colab 项目中。

   • https://www.vonage.com/products/messages/whatsapp/

3. 其他基于云的 WhatsApp API： 还有其他一些基于云的 WhatsApp API 提供商，例如 MessageBird、Infobip 等。可以探索这些选项并选择最适合需求的选项。

示例（使用 Twilio）：

from twilio.rest import Client

# 的 Twilio 帐户 SID 和身份验证令牌
account_sid = "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"  # 替换为的帐户 SID
auth_token = "your_auth_token"  # 替换为的身份验证令牌

client = Client(account_sid, auth_token)

message = client.messages.create(
    body="好，这是来自 Twilio 的 WhatsApp 消息！",  # 的消息内容
    from_="whatsapp:+14155238886",  # 的 Twilio WhatsApp 号码
    to="whatsapp:+1234567890"  # 收件人的 WhatsApp 号码
)

print(message.sid)

请记住，需要注册一个 Twilio 帐户并设置一个 WhatsApp Business 帐户才能使用其 API。

希望这可以帮助到！
