so i'm building an ionic application for android and ios devices.
when i'm trying to build application in android with command 'ionic cordova build android --prod --release', it works fine in (on windows)
butt in ios with the same command (on mac), gives me this error:
10:35:55] typescript error
Cannot find type definition file for '@types'.

The "Cannot find module or its corresponding type declarations" error occurs when TypeScript cannot locate a third-party or local module in our project. To solve the error, make sure to install the module and try setting moduleResolution to node in your tsconfig. json file.
To solve the error "Cannot find type definition file for node", install the node types by running npm i -D @types/node . If the error is not resolved, try adding node to your types array in tsconfig. json and restarting your IDE.
If the package.json file of the package does not explicitly specify the location of a type definition file, Typescript will assume that the type definition file has the same base name and location as the package's main module.
If that doesn't help, make sure the types array in your tsconfig.json file contains "node". Copied! That should fix the "Cannot find type definition file for node" error in your project. When the types option is specified, only the listed packages will be included in the global scope.
Sorry, something went wrong. When types is not specified (this seems to be the case that mystifies the most users): Subdirectory ' {0}' of 'typeRoots' directory ' {1}' is not a valid types package. If the presence of this subdirectory is intentional, change the 'typeRoots' or 'types' option.
This should probably be a warning rather than an error. A missing typedef is equivalent to an empty typedef, which isn't an error condition. Sorry, something went wrong.
This error showed up after upgrading @ionic/app-scripts: 3.2.3 to latest version 3.2.4.
I did not downgrade to fix it
I added
"types": [],
into
"compilerOptions"
in tsconfig.json file and the error was gone.
Now my tsconfig.json file looks like this:
"compilerOptions": {
"types": [], <== fix added here <==
"allowSyntheticDefaultImports": true,
"declaration": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": [
"dom",
"es2015"
],
"module": "es2015",
"moduleResolution": "node",
"sourceMap": true,
"target": "es5"
}
Downgrade the @ionic/app-scripts version to 3.2.3 is worked for me.
npm i @ionic/[email protected]
