Bumping version gives compilation error (arrow-array)

[bmmeijers]

Which part is this question about

When bumping my dependencies from v26 to a higher version, I get a compile time error on my project:

error[E0432]: unresolved import `num::complex::ComplexFloat`

Describe your question

Is this a problem with the arrow / parquet dependencies or do I need to do something on my rust environment?

Additional context

v.26 of arrow and parquet libs works, when going higher to v27 -- v30.0.1give all same compilation error on compiling arrow-array.

[tustvold]

Is there a lockfile present, that is pinning to an older version of num? Perhaps try cargo update num or deleting the lockfile?

[bmmeijers]

Yeah, there is a dependency on num-bigint / num-traits that I did not bump.

[bmmeijers]

Thanks, running cargo update solved it for me.
