$ typings search handsontable
Viewing 2 of 2

but then i cant install that?

Is there some way to use a different "source" than npm?

typings help install

Usage: typings <command>

Commands:
    bundle, i, in, info, init, install, la, list, ll, ls, open, r, remove, rm,
    search, uninstall, view

typings <command> -V   Enable verbose logging

typings --version      Print the CLI version

typings@0.7.12 /usr/local/lib/node_modules/typings

How do I install a typings that is listed with a different homepage?

Or maybe they exist for tsd but not typings?

回答1:

I believe global has replaced ambient as a keyword, and source~packagename is the syntax, for example:

typings install dt~node --global

still unclear what the env or dt typings repo distinctions are. surely dt is the default place that is searched, so why is there a need to specify it?

回答2:

but then i cant install that

Type definitions in DefinitelyTyped are considered ambient. So you need to install with the ambient flag:

typings install --ambient handsontable

More on ambient

When to use ambient while searching for a type definition?

回答3:

You can directly copy a typings file from Definitely Typed Typescript and paste it in your project.

You can also download the whole definitely typed github project from above link, copy and paste the required typings files according to your need.

As @basarat told

typings install --ambient fileName 

would be an another option to download typings file.

For more info on typings file, like how to use them, what they contain look at Definitely Typed.

The ERR message actually suggest what you should do (adding line breaks for SO):

$ typings install handsontable

Is there some way to use a different "source" than npm?

You can configure the defaultSource and defaultAmbientSource in .typingsrc.

回答5:

try using the following command if there is a source for dt or env

typings install --global en~node
