getInstalledPath
Get installed path of globally or locally
namepackage. By default it checks ifnameexists as directory in global-modules directory of the system. Passopts.localto get path ofnamepackage from local directory or fromopts.cwd. Returns rejected promise if module not found in global/localnode_modulesfolder or if it exist but is not a directory.
Params
name{string}: package nameopts{Object}: passopts.localto check locallyreturns{Promise}: rejected promise ifnamenot a string or is empty string
Example
const { getInstalledPath } = require('get-installed-path')
getInstalledPath('npm').then((path) => {
console.log(path)
// => '/home/charlike/.nvm/path/to/lib/node_modules/npm'
})
getInstalledPath('foo-bar-barwerwlekrjw').catch((err) => {
console.log(err.message)
// => 'module not found "foo-bar-barwerwlekrjw" in path ...'
})
getInstalledPath('npm', {
local: true
}).catch((err) => {
console.log(err.message)
// => 'module not found "foo-bar-barwerwlekrjw" in path ...'
})
getInstalledPath('global-modules', {
local: true
}).then((path) => {
console.log(path)
// => '~/code/get-installed-path/node_modules/global-modules'
})
// If you are using it for some sub-directory
// pass `opts.cwd` to be where the `node_modules`
// folder is.
process.chidr('foo-bar-baz')
getInstalledPath('global-modules', {
local: true,
cwd: '../'
}).then((path) => {
console.log(path)
// => '~/code/get-installed-path/node_modules/global-modules'
})
// When searching for the path of a package that is required
// by several other packages, its path may not be in the
// closest node_modules. In this case, to search recursively,
// you can use the following:
getInstalledPath('npm', {
paths: process.mainModule.paths
}).then((path) => {
// ...
})
// `process.mainModule` refers to the location of the current
// entry script.getInstalledPathSync
