Ionic Error: Failed to load resource [How to Solve]

After a day, I found that the code was wrong

The reason for the error is that such a definition is used in the TS file

Data: [] = [‘high tech Zone’, ‘Economic Development Zone’, ‘other parks’]

The error lies in the type of this definition, which cannot be []. If it is modified to any, there will be no problem

Data: any = [‘high tech Zone’, ‘Economic Development Zone’, ‘other parks’]


I don’t know what happened. Suddenly ionic reported an error: failed to load resource   The project cannot be started

The final solution to this problem is to clone the GIT project again . So I didn’t find the reason for the mistake today

Document resolution process

It is found that these missing files are in the build directory

Therefore, execute the build command, but the error is as follows:

I didn’t understand this error and couldn’t find a solution, so I wanted to delete node first_Modules, run the NPM install command again after installing


result error: downloading from GitHub timed out

Downloading binary from
Cannot download "":


Many solutions have been tried here and can be downloaded at last

But when you return to execute the build command, you still report an error and despair
