Recently, because I want to configure the Android development environment, I deleted MyEclipse 5.5 and downloaded the latest version of eclipse 3.7. Because I downloaded the latest version of pydev 2.4 before Python development. After installing the plug-in, when creating a new Python project, I prompted the following error: project interpreter not specified (see Figure 1)

At first, I thought there was a problem with the plug-in installation. Later, after a long time, I found that it was caused by the development environment without importing python

If you know the reason, it’s easy to solve it

Of course, your system must have installed the python installation environment, which is necessary, because eclipse only provides an IDE, and does not provide interpreters, compilers, etc. for various languages

Then follow the steps below

1. From the eclipse menu window — > Preferences opens the preferences configuration
2. On the preferences configuration page, find the pydev item on the left, expand it, and click interpreter – Python (interpreter means interpreter), as shown in Figure 2
3. Then click the new… Button on the right, and the interpreter name will not be filled in. If it is empty, you can select the installation location of python.exe (see Figure 3), and then wait for the import to complete (Figure 4) to solve the problem
