Google cloud Natural Language API error:google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials
Google cloud Natural Language API error:google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials
我使用 Google 云的自然语言 API link:
我在 powershell 中使用这个命令：
$env:GOOGLE_APPLICATION_CREDENTIALS="D:\analyze_sentiment\MyFirstProject-bbe4f7bccb98.json"
然后我在cmd中使用这个命令：
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))
错误信息说：
raise exceptions.DefaultCredentialsError(_HELP_MESSAGE)
google.auth.exceptions.DefaultCredentialsError: Could not
automatically determine credentials. Please set
GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and
re-run the application. For more information, please see
https://developers.google.com/accounts/docs/application-default-credentials.
为什么？
我想你也必须在你的本地机器上设置 GOOGLE_APPLICATION_CREDENTIALS。下载 Google Cloud Shell 并在那里设置凭据
我知道错误原因，我必须使用cmd模式来运行代码，请不要运行带有pycharm或其他IDE.And的代码设置这个link API "enable".
然后错误消失了。
