|
|
|
||
|
|
Name of the package.
|
||
|
|
|
||
|
|
#### options
|
||
|
|
|
||
|
|

##### version
|
||
|
|
|
||
|
|

|
||
|

|
||
|
|
|

|

|
||
|
|
|
||
|
|
The version can also be in any format supported by the [semver](https://github.com/npm/node-semver) module. For example:
|
||
|
|
|
||
|
|
- `1` - get the latest `1.x.x`
|
||
|
|
- `1.2` - get the latest `1.2.x`
|
||
|
|
- `^1.2.3` - get the latest `1.x.x` but at least `1.2.3`
|
||
|
|
- `~1.2.3` - get the latest `1.2.x` but at least `1.2.3`
|
||
|
|
|
||
|

|
|
Type: `boolean`<br>
