Re: Packing problem for instantmusic

[Alex Vong]

Hello,

Since there is a permission error, I try to chmod some files and it
works. Here is the code:


(define-public instantmusic
  (let ((commit "300891d09c703525215fa5a116b9294af1c923c8")

      (name "instantmusic")
      (version (string-append "0.1-" revision "." (string-take commit 9)))
      (source (origin
                (method git-fetch)
                (uri (git-reference
                      (url 
"https://github.com/yask123/Instant-Music-Downloader.git";)
                      (commit commit)))
                (file-name (string-append name "-" version "-checkout"))
                (sha256
                 (base32
                  "0j7qivaa04bpdz3anmgci5833dgiyfqqwq9fdrpl9m68b34gl773"))))
      (build-system python-build-system)

       `(("python-requests" ,python-requests)
