Google云自然语言API错误:google.auth.exceptions.DefaultCredentialsError:无法自动确定凭据 [英] Google cloud Natural Language API error:google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials

问题描述

我从链接:

I use Google cloud's Natural Language API from this link:

我在powershell中使用此命令:

$ env:GOOGLE_APPLICATION_CREDENTIALS =" D:\ analyze_sentiment \ MyFirstProject-bbe4f7bccb98.json"

$env:GOOGLE_APPLICATION_CREDENTIALS="D:\analyze_sentiment\MyFirstProject-bbe4f7bccb98.json"

然后我在cmd中使用此命令:

设置 GOOGLE_APPLICATION_CREDENTIALS = D:\ analyze_sentiment \ MyFirstProject-bbe4f7bccb98.json

set GOOGLE_APPLICATION_CREDENTIALS=D:\analyze_sentiment\MyFirstProject-bbe4f7bccb98.json

但是当我使用python代码时:

from google.cloud import language
from google.cloud.language import enums
from google.cloud.language import types

# Instantiates a client
client = language.LanguageServiceClient()
# The text to analyze
text = u'Hello, world!'
document = types.Document(
    content=text,
    type=enums.Document.Type.PLAIN_TEXT)
# Detects the sentiment of the text
sentiment = client.analyze_sentiment(document=document).document_sentiment
print('Text: {}'.format(text))
print('Sentiment: {}, {}'.format(sentiment.score, sentiment.magnitude))

错误消息说:

引发异常.DefaultCredentialsError(_HELP_MESSAGE) google.auth.exceptions.DefaultCredentialsError:无法 自动确定凭据.请设定 GOOGLE_APPLICATION_CREDENTIALS或显式创建凭据和 重新运行该应用程序.有关更多信息，请参见 https://developers.google.com/accounts/docs/application-default-凭据.

为什么?

我知道错误原因，我必须使用cmd模式运行代码，请不要使用pycharm或其他IDE运行代码. href ="https://console.cloud.google.com/apis/library/language.googleapis.com/" rel ="nofollow noreferrer">链接 API启用".

I know the error reason,I must use cmd mode to run the code,please do not run the code with pycharm or other IDE.And set this link API "enable".

然后错误消失了.
