Defeated by vector

Coming back to C++ after many years; trying to catch up to C++11 & 14. I've read about rvalues and move semantics. I thought I understood the concept. Apparently not. I've looked at dozens of examples. But I simply can't get my code to compile. I must be missing something obvious in the examples. I always get the error about the copy ctor being deleted because of unique_ptr having a user-declared move ctor. There's obviously something I'm missing about the concept, but I can't figure out what it is. Here's the code, stripped down to its essence:

#include <utility>
#include <vector>

int main(int, char*[]) {
  auto oneInt{std::make_unique<int>(0)};
  auto someInts{std::vector<std::unique_ptr<int>>{std::move(oneInt)}};

  return 0;
}

What am I doing wrong?

Edit: Here's the error from this particular code. Note that I've tried every variation on the code that I can think of, with varying results, but the basic problem is always the same: copy ctor deleted because unique_ptr has a user-declared move ctor.
