The Install-Package cmdlet installs one or more software packages on the local computer. If youhave multiple software sources, use Get-PackageProvider and Get-PackageSource to display detailsabout your providers.
Important
The commands contained in the PackageManagement module are different than the commandsprovided by the NuGet module in the Package Manager Console of Visual Studio. Each module hascommands that are not available in the other. Commands with the same name differ in their specificarguments. For more information, see the PowerShell reference documentation for thePackage Manager Console of Visual Studio.
Examples
Example 1: Install a package by package name
The Install-Package cmdlet installs a software package and its dependencies.
PS> Install-Package -Name NuGet.Core -Source MyNuGet -Credential Contoso\TestUserInstall-Package uses parameters to specify the packages Name and Source. TheCredential parameter uses a domain user account with permissions to install packages. Thecommand prompts you for the user account password.
Example 2: Use Find-Package to install a package
In this example, the object returned by Find-Package is sent down the pipeline and installed byInstall-Package.
PS> Find-Package -Name NuGet.Core -Source MyNuGet | Install-PackageFind-Package uses the Name and Source parameters to locate a package. The object is sentdown the pipeline and Install-Package installs the package on the local computer.
Example 3: Install packages by specifying a range of versions
Install-Package uses the MinimumVersion and MaximumVersion parameters to specify a rangeof software versions.
PS> Install-Package -Name NuGet.Core -Source MyNuGet -MinimumVersion 2.8.0 -MaximumVersion 2.9.0Install-Package uses the Name and Source parameters to find a package. TheMinimumVersion and MaximumVersion parameters specify a range of software versions. Thehighest version in the range is installed.
