I got exactly the same error.

It works good without the --pyz option, but as soon as i put the --pyz option, i got the same bug.

Did you manage to correct the issue?

Hi sunapi386, xvolte, You can fix the problem by edit the call to "compression.zip_pack(files, options)" in __init__.py to "compression.zip_pack(files[0], options)" since it was expecting one python file anyway. files variable was a list or tuple but zip_pack() function "cumulative_size += os.path.getsize(filepath)" expect a string. Cheers.

Hello @lwhowe

Thanks for your help. Unfortunately, the package is installed through pip installer,

do you know how i can make the changes ?

thanks in advance,

Hello,

i managed to change it here : notepad c:\python27\lib\site-packages\pyminifier\__init__.py but now i have a new problem: IOError: [Errno 13] Permission denied: 'c:\\users\\xavier\\appdata\\local\\temp\\tmptdced0'

But i opened the shell as admin, same error! (the folder does not exists)

hi @xvolte, guess you are using the pyz option. It works for me in Linux but same problem with yours in Windows.
