Try changing the `lib` compiler option to es2015 or later

See original GitHub issue

When I try to use ts-json-schema-generator with angular I get an error:

/node_modules/@angular/common/src/directives/ng_class.d.ts(48,34): error TS2583: Cannot find name 'Set'. Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later.
/node_modules/@angular/common/src/pipes/keyvalue_pipe.d.ts(47,9): error TS2583: Cannot find name 'Map'. Do you need to change your target library? Try changing the `lib` compiler option to es2015 or later.

This error is the same as https://github.com/vega/ts-json-schema-generator/issues/47

To reproduce:

npm install -g @angular/cli
ng new my-app
cd my-app
npm install ts-json-schema-generator
npx ts-json-schema-generator  --path src/main.ts --type string

In the other issue, you propose to use ts-json-schema-generator --path tsconfig.json but in my case I really need to specify the file to search for types. I don’t want ts-json-schema-generator to scan the whole project.

Also, if I copy the node_module outside the project and install the dependency, it is then working.

cp -r  my-app/node_modules/ts-json-schema-generator .
cd ts-json-schema-generator
npm install
npx ts-json-schema-generator  --path ../my-app/src/main.ts --type string

But I need ts-json-schema-generator to be part of the dependency of my project.
