EDIT: I’ve tried running the code linked in the duplicate flag, it’s posted here for reference, and it doesn’t run. I had already referred to that answer in my initial post.

My problem

Downloaded shapefile is missing .shx file and trying to use pyshp to build it on a mac.*

I’ve tried this code that I’ve picked up from the pyshp documentation. When checking the r.shapes and r.records, it looks like all of the info is there.

myshp = open("Stockton/Stockton.shp", "rb")
mydbf = open("Stockton/Stockton.dbf", "rb")
r = shapefile.Reader(shp=myshp, dbf=mydbf, shx=None)

In the documentation, it looks like each record and shape is being added one at a time. Is there a method I’m missing? Or could a list comprehension be used here to loop through everything?**

Data and References

I’ve downloaded the Microsoft Building Data for Stockton CA from here. I’ve tried to follow the code from the answer here

    # Build a new shx index file
    #Code by Joel Lawhead http://geospatialpython.com/2011/11/generating-shapefile-shx-files.html
    import shapefile
    # Explicitly name the shp and dbf file objects
    # so pyshp ignores the missing/corrupt shx
    myshp = open("Stockton/Stockton.shp", "rb")
    mydbf = open("Stockton/Stockton.dbf", "rb")
    r = shapefile.Reader(shp=myshp, shx=None, dbf=mydbf)
    w = shapefile.Writer(r.shapeType)
    # Copy everything from reader object to writer object
    w._shapes = r.shapes()
    w.records = r.records()
    w.fields = list(r.fields)
    # saving will generate the shx
    w.save("myshape")

but get this error:

TypeError                                 Traceback (most recent call last)

----> 9 w = shapefile.Writer(r.shapeType)
     10 # Copy everything from reader object to writer object
     11 w._shapes = r.shapes()

...

*Because I’m using a Mac, none of the solutions here seem like they would work.

**Still fairly new to Python so please forgive wrong/confusing terminology.
