Should fix the issue.

In #6 (comment) you pointed out that the issue might be the usage of filepath.Clean. What do you think about removing the filepath.Clean reference and replacing it with an URL fitting pattern? e.g. typical URL encoding?
Have a look at https://www.urlencoder.io/golang/ to check if one of those might be a good choice.

Hi
My experience with go is only 1 hr, so code might be improved. The main advantage of filetpath.Clean is it removes some unwanted stuff from the package name. But there might be better ways.

Hi

The following replacement appears to work on Windows (and using net/url):

	//u := fmt.Sprintf("%s/packages%s.json", c.url.String(), strings.Replace(filepath.Clean("/"+name), "\\", "/", -1))
	u, err := url.Parse(c.url.String())

	// Note: not sure this code is necceasry (as the url.Parse can't fail):
	//if err != nil {
	//	return nil, nil, err
	//}

	u.Path += "/packages"
	u.Path += fmt.Sprintf("/%s.json", name)

	resp, err := c.httpClient.Get(u.String())

I'm not sure the first if statement is necessary as the packagist.org URL is probably hardcoded and not modifiable using a command line switch (so the url.Parse() can't fail.

Personally I think this is indeed a better solution (properly building the url instead of stitching it together as a string)
