python - Google Cloud Translate API 客户端属性

Question

我正在尝试使用 Google Translate API。我已经按照他们的指南安装了所需的库并创建了一个虚拟环境。但是，在运行网站上提供的以下示例代码时，我不断收到有关库属性的错误消息:

"""Translates text into the target language.

Target must be an ISO 639-1 language code.
See https://g.co/cloud/translate/v2/translate-reference#supported_languages
"""
from google.cloud import translate_v2 as translate
translate_client = translate.Client()

if isinstance(text, six.binary_type):
    text = text.decode('utf-8')

# Text can also be a sequence of strings, in which case this method
# will return a sequence of results for each text.
result = translate_client.translate(
    text, target_language=target)

print(u'Text: {}'.format(result['input']))
print(u'Translation: {}'.format(result['translatedText']))
print(u'Detected source language: {}'.format(
    result['detectedSourceLanguage']))

输出:

    from google.cloud import translate_v2 as translate

    translate_client = translate.Client()
AttributeError: module 'google.cloud.translate_v2' has no attribute 'Client'

为什么会出现此错误？

鉴于很长一段时间都没有答案，我将总结克里斯托弗在评论中给出并由奥马尔测试的答案。如果帖子得到妥善解决，帖子应该有一个可接受的答案，以提高帖子的可见性，以便遇到类似问题的其他用户可以更快地找到它。

问题的根本原因 AttributeError: module 'google.cloud.translate_v2' has no attribute 'Client' was found in the environment itself。创建一个全新的虚拟环境并重新安装依赖项解决了这个问题。
