[patrickweegen]

Description

When installing the NuGet-package using paket, an IOException is thrown:

Paket failed with

    In rare cases a firewall might have blocked the download. Please look into the file and see if it contains text with further information.

Expected behavior:

The package should be installed like using any other package manager

Actual behavior:

An IOException (see above) is thrown and the package cannot be installed.

Versions

• Which version of Fluent Assertions Analyzers are you using? --> 0.11.4
• Which .NET runtime and version are you targeting? --> .NET Core 2.1

Additional Information

When inspecting the pacakge I noticed that there are two files with the same name conatined in the same folder.

does packet execute the tool/install.ps1 script and then fail?

[patrickweegen]

As far as I can see when I run paket install --verbose the install.ps1 gets not executed.

Bit this looks correct after reading those Issues:
VS 2017 doesn't execute install.ps1 from packages if used as PackageReference
Come up with a strategy for packages that have install.ps1/uninstall.ps1

[Meir017]

looks like this error is out of the scope of this project

[patrickweegen]

I don't think so, @Meir017
If the package gets created in a different way it would work.

[Meir017]

@patrickweegen, Do you have an example of an Analyzers nuget package that can be installed using packet?

[patrickweegen]

I have successfully installed the FakeItEasy.Analyzer.Csharp.
