On Windows with pipeline 1.4.6, cannot find files due to quotes

[ses4j]

  File "C:\wc\...\lib\site-packages\react\jsx.py", line 50, in transform
    with open(jsx_path, 'rU') as i:
IOError: [Errno 22] invalid mode ('rU') or filename: u"'C:\\...\\staticfiles\\jsx\\my_jsx_file.jsx'"

Single quotes (') surround the jsx_path and js_path sent in from pipeline, as you can see from the error message thrown above. It comes from their shlex.quote call here: https://github.com/cyberdelia/django-pipeline/blob/master/pipeline/compilers/__init__.py#L43

I currently hacked around it by replacing the transform(...) in C:\wc...\lib\site-packages\react\jsx.py with this:

def transform(self, jsx_path, js_path=None, **kwargs):
    if jsx_path.startswith("'"):
        jsx_path = jsx_path[1:-1]
    with open(jsx_path, 'rU') as i:
        js = self.transform_string(i.read(), **kwargs)
        if js_path:
            if js_path.startswith("'"):
                js_path = js_path[1:-1]
            with open(js_path, 'wb') as o:
                o.write(js.encode('utf8'))
        return js
