出现typeScript错误“模块，类，接口，枚举，导入或声明”

Question

I'm trying to understand why this line invokes an error:

const value = 20 * 30;

error TS1008: Unexpected token; 'module, class, interface, enum, import or statement' expected.

any idea?

Answer 1

Here is the solution:

Earlier on my machine I had installed Visual Studio 2015 Pro Edition. that had installed TypeScript 1.0.3.0. and added its path to system environment.

Now I used npm install -g TypeScript and it did install, however from command line, typing tsc --version was always giving 1.0.3.0.

I removed the older path from environment and then restarted code and it worked fine.

Better you check your versions and the solution might help.

Answer 2

It doesn't cause an error for me: https://jsfiddle.net/n0w1jt7b/

const value = 20 * 30; // 600

Be sure that all your versions are up-to-date.
