Boilerplate project from `dx new` does not build

**Problem**

I am trying to get up and running with the tutorial, but the resulting project does not compile with `dx build` (though it does build with `cargo build`).

**Steps To Reproduce**

Steps to reproduce the behavior:

For maximum reproducibility, this is the *shell.nix* file I am using:

```nix
let
# a recent commit to the unstable channel
nixpkgs = fetchTarball "https://github.com/NixOS/nixpkgs/archive/fa35a3c8e17a3de613240fea68f876e5b4896aec.tar.gz";
pkgs = import nixpkgs {
config = { };
overlays = [];
};
in
pkgs.mkShell {
buildInputs = with pkgs;[
at-spi2-atk
atkmm
cairo
gdk-pixbuf
glib
gtk3
harfbuzz
librsvg
libsoup_3
pango
webkitgtk_4_1
openssl
];
nativeBuildInputs = with pkgs; [
pkg-config
gobject-introspection
cargo
cargo-tauri
nodejs
];
packages = with pkgs; [
dioxus-cli
emacs
git
wasm-pack
];
RUST_BACKTRACE = 1;
RUSTFLAGS = "-Awarnings";
}
```

Then:

```bash
dx --version
[el@nixos:~]$ dx --version
dioxus 0.6.0 (was built without git repository)

[el@nixos:~]$ dx new hot_dog

```

I can produce the same behavior as well by removing `dioxus-cli` from the *shell.nix*, removing *~/.cargo/*, and starting from `cargo install dx`.

**Expected behavior**

I would expect the freshly-generated project to build successfully.

**Screenshots**

**Environment:**

- Dioxus version: 0.6.0 from nixpkgs and 0.6.3 from cargo
- Rust version: (using the version packaged with `dioxus-cli` and `cargo` in the unstable nix channel
- OS info: NixOS
- App platform: web
