How can I prevent nuget from reinstalling packages if no newer version was found?



I'm using the nuget cmd tool in order to install the build tool "FAKE - F# Make" ( via the following script:

"tools\nuget\nuget.exe" "install" "FAKE" "-OutputDirectory" "tools" "-ExcludeVersion"

Unfortunately nuget deinstalls and reinstalls FAKE every time I run the script even if no newer FAKE version was detected. How can I tell nuget to keep the current installation if no newer version was found?

verified using latest 2.8 nuget.exe

BTW: I don't want to use the -Version flag since my build should always use the latest FAKE version.

This is by design because you include the -ExcludeVersion parameter. When it is present, NuGet cannot determine what the current version you already have, so it just blindly uninstall and reinstall the package.

Actually nuget knows exactly which version it has installed:

From the output:

Successfully uninstalled 'FAKE'.
Successfully installed 'FAKE'.

The original pull request was rejected because of no reply to code review comments. Implemented our own fix:

repro steps:
  1. create a new F# project
  2. install nuget.commandline and FAKE package to the project
  3. at the root of the project, make tools\nuget folder and copy nuget.exe to it
  4. start command prompt, type "tools\nuget\nuget.exe install fake -outputdirectory tools -excludeversion" and make sure tools\fake folder is generated with fake.nupkg
  5. type "tools\nuget\nuget.exe install fake -outputdirectory tools -excludeversion" again
  6. verify the output on the command prompt
expected to see that "Package 'fake' is already installed"
