我在 Ubuntu Linux 服务器上运行 Pyramid ，在尝试使用 pyramid_mailer 时遇到了 ValueError。我的代码比较简单，似乎任何东西都会导致它:
def my_view(request):
mailer = get_mailer(request)
emailMessage = Message(subject="Welcome", sender="noreply@mysite.com", recipients = ["me@email.com"], body="test")
mailer.send(emailMessage)
导致此错误:
Traceback (most recent call last):

ValueError: TPC in progress
我按照以下网站上的“入门(更简单的方法)”的说明进行操作:http://pyramid-mailer.readthedocs.org/en/latest/
最佳答案
这是一个 known issue .同时可以通过恢复到 repoze.sendmail 4.1(从 4.2 开始)来解决这个问题
关于python - 使用 pyramid_mailer 导致 ValueError : TPC in progress，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23861277/
