parse error by packrat

[renejuan]

This is more a recommendation; while parsing packrat will throw an error that looks like:

Failed to parse dependencies in this file will not be discovered

It may be a good idea to suggest the person to look at such script; as there may be a syntax error (e.g., open parentheses) that is causing such error.

I think the Failed to parse line should help imply this (ie, we couldn't parse this because there's a parse error). Of course, it would be great if packrat could report this more properly.

I create a project on OSX and everything is fine. Now I'm on windows and packrat::status says the warnings... It's really weird and everything works fine, too. I doubt it might due to the line ending conversion?

[shrektan]

I get it. If my file contains UTF-8 characters, the warning will show up...

[kevinushey]

What version of packrat are you using? We recently fixed up some UTF-8 related issues seen on Windows; can you ensure that you have the latest CRAN version?

[shrektan]

@kevinushey It's the lastest version of packrat on CRAN, which is 0.4.8.1. And I'm pretty sure it's caused by the UTF-8 chars in the script, since there's no warning after removing those characters.

Below is my session info, if it helps. If there's anything more that can help you identify the problem, please tell me how to do it. I would be glad to provide, thanks.
