我试着运行这段使用谷歌云的代码。
import signal
import sys
from google.cloud import language, exceptions
# create a Google Cloud Natural Languague API Python client
client = language.LanguageServiceClient()但它提供了以下错误消息:
Traceback (most recent call last):
File "analyse-comments.py", line 7, in <module>
client = language.LanguageServiceClient()

explicitly create credential and re-run the application. For more
information, please see
https://developers.google.com/accounts/docs/application-default-credentials.第7行是代码的这一部分
client = language.LanguageServiceClient()我已经安装了google和云。我有谷歌的解决方案,但没有一个解决方案适合我的情况下需要解决的问题。

您共享的错误明确指出,凭据存在问题:
google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or
explicitly create credential and re-run the application.它还邀请您访问文档页以获得有关设置身份验证主题的更多信息:
For more information, please see https://developers.google.com/accounts/docs/application-default-credentials.这里的具体问题是,您正在使用的客户端库(google.cloud.language)试图在环境变量GOOGLE_APPLICATION_CREDENTIALS中直接找到使用您的GCP帐户进行身份验证的凭据,但无法找到它们。为了解决这个问题,您应该首先从控制台中的服务帐户页下载服务帐户的JSON密钥(单击右边的三个点并创建一个新的JSON键),在本地存储它,然后根据操作系统发行版的不同使用GOOGLE_APPLICATION_CREDENTIALS作为在文件中解释指向它。
一旦使用JSON键的正确目录路径填充了这个环境变量,您使用的客户端库将能够正确地进行身份验证,并且错误应该会消失。
此外,如果该过程对您不起作用(我没有看到任何原因),您可以将凭据文件显式地传递给正在实例化的LanguageServiceClient(),如下面所示,详见自然语言API的API参考。
from google.cloud import language
from google.oauth2 import service_account
creds = service_account.Credentials.from_service_account_file('path/key.json')
client = language.LanguageServiceClient(
credentials=creds,
