Installing specific version of package

[d_wozny]

I am using command line for nipkg instalation. I would like to specify a version of the package to install but so far without success. I looked into help but could not find information about package version during instalation

C:\Program Files\National Instruments\NI Package Manager>nipkg install package_name 1.0.0-0 -y -allow-downgrade

It must be something silly and simple.

I will give myself a kudo 🙂 This was more reverse engineerig process than anything and combining knowledge from different package managers I worked out that  command should be:

What nipkg tells you once you create syntax error (only then!!!)

But what is version operator? Now I think it is '='

Post for somebody with the same struggles as me.

d_wozny, you are correct. The operator for specifying the version is '='. However, the version also needs to be the full version as specified in the package's attributes (see version by running "nipkg info <package_name>"), which, for NI products, is generally in the form of '1.0.0-0+f0'.

To clarify and be more specific, as the error message stated, the correct syntax is to specify a "version_operator", which can be any debian based version operator, which currently includes the following { <=>, !=, >=, <=, >>, <<, <>, >, <, = }. Obviously the most recognized and common being '='. Please use the other operators with care if you are not already familiar with their use.

Thanks for extra info. Although it might be obvious for somebody using Linux it would be beneficial for this information be statet in help to some extent.
