Accessors are only available when targeting ECMAScript 5 and higher

Question

I am trying to run this code but it is giving me following errors:

Animal.ts(10,13): error TS1056: Accessors are only available when targeting ECMAS

Answer 1

Had the same issue, got it worked with this... for a single file!

tsc -target "es5" filename && node filename

• "es5" with quotes

• need not mention file extensions

• tsc -target "es5" filename - transpiles the typescript to "es5" JavaScript

• node filename - runs the transpiled javascript file

Answer 2

I know that is an old conversation, but i think that solution bellow could be a very helpful command for all developers here.

You can easily solve using this command in your Terminal, Command Prompt, Git Bash and etc:

tsc --target ES2016 Animal.ts --watch

or

tsc --target es5 Animal.ts --watch

--watch is optional and means that you doesn't need to compile your code in each modification.
