After you install Pydev on your MacBook, you find that you don't have pydev options after you create a new project. A search on the official website found that the JDK version was too long. The latest JDK (url:http://www.oracle.com/technetwork/java/javase/downloads/index.html) is downloaded on the Oracle website and is displayed properly after installation.
And the update address in the video and most tutorials on the Web: http://pydev.org/updates/is also problematic. I downloaded the latest pydev,update address on Eclipse Marketplace for http://pydev.sf.net/updates/
If there is no way to install Pydev, you can also directly download the Pydev, direct manual installation.
Go to Pydev's homepage and choose the dev version corresponding to your Python version, preferably with the same version number, or there may be an error pydev the option. http://sourceforge.net/projects/pydev/files/pydev/
Copy the contents of the plugins and features folders in the downloaded Pydev compressed package to the corresponding folder in the extract directory of Eclipse.
