A Red Cross occurs in the pydev import extension module.

Today, I compiled a c extension module and copied it to the python library directory (D: \ Program Files \ python2_7 \ DLLs,

A Red Cross occurs when it is imported to the system, but it is strange that it can be called, so I checked it. It turns out that the database needs to be reloaded.

There are two methods:

Method 1: Go to Windows> Preferences> Pydev> Interpreter-Python and go to the Forced Builtins page.

Add the name of the imported module to a New project. After applying, Pydev will find the names of these modules in lib again,

In this way, no error is prompted in the code.

Method 2: Go to the Windows> Preferences> Pydev> Interpreter-Python menu and click Apply in the lower right corner of Libraries,

Let Pydev Reload all modules to complete the above tasks. This should be better than the previous method.
