JSON parse error. This will only appear in moon.pkg.json files only.

It is very like that the editor you are using will have support for JSON installed (for example, Visual Studio Code has a built-in JSON parser). This error is likely to be caused by a missing comma or a missing closing brace.

Erroneous example

{
  "is-main": true
  "import": [] // Error: Expect_comma_or_rbrace
}

Suggestion

{
  "is-main": true,
  "import": []
}
