Looking at node_dlang's dub.json, it's building a DLL then
renaming it to module.node. The JS script then causes node to
load the DLL.
So I expect this error may be related to a 32-bit vs. 64-bit
issue. I assume you are on 64-bit Windows, in which case recent
versions of dub compile as 64-bit by default. So if that's the
case, and your installation of node is 32-bit, you would see
this error. Ditto when you're loading a 32-bit DLL in a 64-bit
process.
the npm was 32bit so the switch to 64bit worked then npm
example.js ran file but electron requires a 32bit module, so I
need to switch back to npm 32bit. Now, I can't build the example
from node_dlang with --arch=x86, returns the error:
command:
```$ dub --arch=x86```
output:
```
