How to Solve Echarts Error: import echarts from ‘echarts‘

The following commands are required for normal angular installation of echarts

1 npm install echarts -S
2 npm install ngx-echarts -S

However, an error prompt is found after installation, and the type is marked in red in the file reference

1. The following commands need to be executed

1 npm install echarts -S
2 npm install ngx-echarts -S
3 npm install @types/echarts -D

2. Introduce modules into modules (such as app.Module.TS):

1 import { NgxEchartsModule } from 'ngx-echarts';
2 @NgModule({
3   imports: [
4     ...,
5     NgxEchartsModule
6   ],
7 })
8 export class AppModule { }

[Solved] Angular&CI/CD：Error: initial exceeded maximum budget

During CI/CD process of angular project, the following errors occur:

Warning: initial exceeded maximum budget. Budget 2.00 MB was not met by 3.01 MB with a total of 5.01 MB.
Error: initial exceeded maximum budget. Budget 5.00 MB was not met by 6.83 kB with a total of 5.01 MB.

The packed file is too large for the specified file size

Solution: modify the angular in the project JSON configuration file (memory parameters)

 "budgets": [{
                  "type": "initial",
                  "maximumWarning": "2mb",
                  "maximumError": "6mb"
                },
              ]

I originally set the maximum error to 5MB, but now I can set it to 6MB. The specific problem depends on the situation

angular.js Error:[$ injector:modulerr ]Why

Error prompt is shown in the figure below:

What’s causing it: Punctuation errors. [note, the test in this paper is tested in the punctuation in the array, the errors caused by other parts of punctuation have not been sorted out]
Example:

As can be seen from the first picture above, two errors are reported. If there is a punctuation problem, the second error is exactly the same, but the first error may occur in the following ways :(may not be complete, please add in the comments below)

The above problem is basically concluded to be a punctuation problem, which can be checked globally for the presence of Chinese punctuation before other screening.
