问题描述
除了 send_email() 之外，其他一切都有效。无论我使用 const matchSlugs6 = (name) => (posts) =>
map (
prop('node'),filter (
compose (any (propEq ('slug',name)),path (['node','categories'])),posts
)
)
还是远程主机，我都会遇到相同的异常。我的猜测是我没有在正确的地方推送上下文，但我已经盯着这个看了很长时间，我显然没有看到错误。任何帮助将不胜感激！

解决方法
将 main = [
['I','want','dog'],['driving','a','car'],['S','O','S']
]
leading = iter(['yes','no','yes'])
joined = [[next(leading),' '.join(m)] for m in main]
import csv
with open('output.csv','w') as f:
writer = csv.writer(f)
writer.writerows(joined)
中的两个函数合二为一以避免上下文问题：
email.py第一次尝试效果很好。我查看了其他 Stackoverflow 帖子并收到了将 def send_email(to,subject,template,**kwargs):
app=current_app
with app.app_context():
msg = Message(app.config['MAIL_SUBJECT_PREFIX'] + subject,sender =
app.config['MAIL_SENDER'],recipients=[to])
msg.body = render_template(template + '.txt',**kwargs)
msg.html = render_template(template + '.html',**kwargs)
Thread(target=mail.send(msg)).start()
导入此模块的建议。我建议不要走这条路。我有两个实例，而不是一个或相同的异常，具体取决于 create_app 调用的位置。
