fix: disable sourceMap in NPM package

[tanghongxin]

Description

When I am debugging my own TS project, if source-map is enabled, the stack information points to some non-existent files.

Minimal code-snippet showcasing the problem

tsc
node --enable-source-maps bundle/index.js

Expected behavior

The stack track the correct file.

Actual behavior

The source files pointed by source-map does not exist becasue they are not published on NPM at all, like this:
