I think you are saying that you have python2 and python3 installed and have added a reference to each version under Pycharm > Settings > Project Interpreter

我想你说你安装了python2和python3并在Pycharm> Settings> Project Interpreter下添加了对每个版本的引用

What I think you are asking is how do you have some projects run with Python 2 and some projects running with Python 3.

我想你问的是你如何使用Python 2运行一些项目，以及一些使用Python 3运行的项目。

If so, you can look under Run > Edit Configurations

如果是这样，您可以在“运行”>“编辑配置”下查看

This can also happen in Intellij Ultimate, which has PyCharm integrated. The issue is as diagnosed above, you have the wrong interpreter selected.

这也可能发生在Intellij Ultimate中，它集成了PyCharm。问题如上所述，您选择了错误的解释器。

The exact method to fix this for any given project is to go to Project Settings...Project and adjust the Project SDK. You can add a New Project SDK if you don't have Python 3 added by navigating to the python3 binary. This will fix the errors listed above. A shortcut to Project Settings is the blue checkerboard-type icon.

为任何给定项目修复此问题的确切方法是转到项目设置...项目并调整Project SDK。如果您没有通过导航到python3二进制文件而添加Python 3，则可以添加新项目SDK。这将解决上面列出的错误。 “项目设置”的快捷方式是蓝色棋盘类型图标。

You can also add Python 3 as the default interpreter for Python projects. On OSX this is in File..Other Settings...Default Project Structure. There you can set the Project SDK which will now apply on each new project. It can be different on other platforms, but still similar.

您还可以添加Python 3作为Python项目的默认解释器。在OSX上，这是在File..Other Settings ... Default Project Structure中。在那里，您可以设置Project SDK，它现在将应用于每个新项目。它可以在其他平台上有所不同，但仍然相似。
