typings - “(No dependencies)” when running “typings install” to get type definitions (TypeScript)
You have an apparently well-defined typings.json file in your current directory/package, such as:
{
"ambientDevDependencies": {
"angular-protractor": "registry:dt/angular-protractor#1.5.0+20160425143459",
"jasmine": "registry:dt/jasmine#2.2.0+20160412134438",
"selenium-webdriver": "registry:dt/selenium-webdriver#2.44.0+20160317120654"
},
"ambientDependencies": {
"es6-shim": "registry:dt/es6-shim#0.31.2+20160317120654"
}
}
But when you try to typings install them you get a No dependencies message (or should we say error?):
$ typings install
└── (No dependencies)
Solution
Rename:
ambientDevDependenciestoglobalDevDependenciesambientDependenciestoglobalDependencies
In our example typings.json file above, the result would be:
{
"globalDevDependencies": {
"angular-protractor": "registry:dt/angular-protractor#1.5.0+20160425143459",
"jasmine": "registry:dt/jasmine#2.2.0+20160412134438",
"selenium-webdriver": "registry:dt/selenium-webdriver#2.44.0+20160317120654"
},
"globalDependencies": {
"es6-shim": "registry:dt/es6-shim#0.31.2+20160317120654"
}
}
Then, at the console:
$ typings install
├── es6-shim (global)
├── angular-protractor (global dev)
├── jasmine (global dev)
└── selenium-webdriver (global dev)
Reason
See typings v1.0.0 release notes:
Many breaking changes (see https://github.com/typings/core/releases/tag/v1.0.0)
- Renamed
ambienttoglobal- …
When typings was updated from version 0.x to 1.x, the properties were renamed, as you can see in the changelog above.
As a consequence, your file that would be fine for version 0.x is not so cool at 1.x.
And that’s it.
