Hi,

I have an options hash map as a run method’s second parameter

I am currently doing this

run File.join(File.dirname( **FILE** ), “…/projects/#{filename}”, {"-  
fh:" =\> “C:/rspec\_reports/#{filename}.htm”})

But I am recieving this error

`join’: can’t convert Hash into String (TypeError)

Could anyone give me the correct syntax please?

Aidy

Try this:  
run File.join(File.dirname( **FILE** ), “…/projects/#{filename}”, “-  
fh: =\> C:/rspec\_reports/#{filename}.htm”)

Aidy, you call the run method with only one parameter, the result of  
File.join. The hash is the third parameter to File.join.
