As a beginner of wechat app, I didn’t expect to run the code that day with a few surprises and errors

after searching for a long time, baidu looked around and finally looked at the official documents. It turned out that the version was too low. It was suggested to set a higher version

The version settings are as follows:
Step 1: click the details in the upper right corner and a pop-up box will appear

Step 2: select local settings from the three tabs of basic information, local settings and project configuration to find the basic debugging library, Select the version 2.16.0 from the drop-down box

method: find project.config.json in the applet directory, find the setting configuration object, and set checksitemap to false, Finally, save and restart the developer tool
