从google.cloud导入ModuleNotFoundError:没有名为“google”的模块
提问于 2019-02-22 12:50:33
我无法让我的应用程序从Google读取文档。
这是我的python烧瓶main.py
from flask import Flask
from google.cloud import firestore
app = Flask(__name__)
db = firestore.Client()
@app.route('/')
def hello():
posts_ref = db.collections(u'posts')
posts = posts_ref.get()
for post in posts:
return u'{} => {}'.format(post.id, post.to_dict())
if __name__ == '__main__':
app.run(host='127.0.0.1', port=8080, debug=True)但是，日志显示了以下错误。

正如达斯汀-英格拉姆建议的那样，很可能您没有正确导入google.cloud.firestore (可能还有flask)包。
一个好的实践是创建一个virtualenv，一个requirements.txt，然后创建pip install -r requirements.txt。其内容可能是：
flask==1.0.2
google-cloud-firestore==0.31.0您的代码中还有一个错误；它是collection而不是collections
posts_ref = db.collection(u'posts')您需要在您的项目中启用Firestore (并且可能在运行代码之前创建posts集合)。
