“Module x is in x.d which cannot be read” error when compiling a d program

问题

Here is the project structure:

.
├── dub.json
├── dub.selections.json
├── dub.userprefs
├── source
│   └── app.d
└── testd2

Content of app.d

import std.stdio;
import scid.matrix;
import colorize: fg, color, cwriteln, cwritefln;


void main()
{
    cwriteln("This is blue.".color(fg.blue));
    auto c = "red";
    cwritefln("This is %s".color(c), c);
}

Content of dub.josn:

{
    "name": "testd2",
    "description": "A minimal D application.",
    "copyright": "Copyright © 2014, kaiyin",
    "authors": ["kaiyin"],
    "dependencies": {
        "colorize": ">=1.0.5"
    }
}

Build error:

dub build

Running dmd...

source/app.d(2): Error: module matrix is in file 'scid/matrix.d' which cannot be read

Any ideas about what went wrong? Thanks.

回答1:

Ok, my fault, I forgot to specify the dependency in dub.json, it should be:

{
    "name": "testd2",
    "description": "A minimal D application.",
    "copyright": "Copyright © 2014, kaiyin",
    "authors": ["kaiyin"],
    "dependencies": {
        "colorize": ">=1.0.5",
        "scid": ">=0.1.0"
    }
}

Next time I see this kind of error, I will remeber to look there.
