解决方案

避免这些问题的最简单的方法是创建一个虚拟环境

 >>>> pip install virtualenv 
 
>>> cd my_project_folder 
>>  virtualenv venv 
  

现在激活您的虚拟环境

 >> ;> source venv / bin / activate 
  

现在安装在那里 pip install Flask - 邮件

希望现在它应该在那里工作

如果你完成工作，然后停用它

 >>>停用
  

或

似乎所有的问题都是因为 certifi 版本冲突

所以尝试从这里下载源
https://pypi.python.org/pypi/certifi

并从源安装

将其解压缩到文件夹并运行此命令

  sudo python setup.py install 
  

它应该工作

I am trying to send an email using Flask when a user registers on my website. I used the command pip install Flask-Mail to install. However, I get the following error of possible version mismatch:

Any possible workarounds? Any help will be greatly appreciated. Thanks!

解决方案

The easiest way to avoid these kind of problems is to create a virtual environment

>>>pip install virtualenv

>>>cd my_project_folder
>>>virtualenv venv

now activate your virtual environment

>>>source venv/bin/activate

now install there pip install Flask-Mail
hopefully now it should work there

if your done working then deactivate it

 >>>deactivate

or

It seems like all the problem is because of certifi version conflict

so try downloading the source from here https://pypi.python.org/pypi/certifi

and install from source

Extract it go into the folder and run this command

sudo python setup.py  install

and it should work
