 Reporter:  fmw42   |      Owner:  stromnov@…
     Type:  defect  |     Status:  assigned
 Priority:  Normal  |  Milestone:
Component:  ports   |    Version:  2.8.1
 Keywords:          |       Port:  opencv4
--------------------+------------------------
 I am on Mac OSX Monterey on M1 Mac (Mini)

 I was trying to upgrade my existing ports that I have been using for quite
 a while.

 I have done the sudo port selfupdate. Then upgraded most of my relevant
 ports. Then tried numerous times to upgrade either opencv4 or
 py39-opencv4. Other ports that try to upgrade opencv4 also report this
 error. I kept getting an error:


 {{{
 "Error: Failed to extract opencv4: extract.rename: multiple directories

 }}}


 I reported that error at https://trac.macports.org/ticket/66942

 Now when I try use any of my existing OpenCV scripts it objects to
 importing cv2:


 {{{

 }}}

 I was told to report this as a separate ticket.
