Too long path exception raised to a specific version of a package - nuget

Question

I built my private Nuget repository on Azure free app service.
And I added the url into Visual Studio 2015.
There is a package having three versions 1.0.3~1.0.5.
The problem is only 1.0.3 version of the package will be successfully installed.
Others are always failed due to the exception (Too long path or file name).
I don't know why they show me different results.
Non of settings are different.
Also I placed the project folder on the root of D: drive.
Please see the log and let me know the reason :D

Answer 1

I am not sure, but I resolved my problem.
I just added supported framework versions into nuspec file.
<dependencies>
<group targetFramework=".NETFramework4.5" >
...
</group>
<group targetFramework=".NETFramework4.0" >
...
</group>
</dependencies>
Anyway it is working that I expected.
