Force installation of a pkg

New to Julia
1

Hello, im using julia 1.4.2, i have sucefully installed and used ReinforcementLearning.jl then i decided to install
Pkg.add("POMDPs"); Pkg.add("QMDP")

which caused:

   Updating `~/x/Project.toml`
  [a93abf59] + POMDPs v0.9.1
  [158674fc] ↓ ReinforcementLearning v0.7.0 ⇒ v0.6.0
   Updating `~/x/Manifest.toml`
  [31c24e10] ↓ Distributions v0.24.3 ⇒ v0.23.12
  [d9ec5142] + NamedTupleTools v0.13.7
  [f3bd98c0] + POMDPLinter v0.1.1
  [a93abf59] + POMDPs v0.9.1
  [158674fc] ↓ ReinforcementLearning v0.7.0 ⇒ v0.6.0
  [de1b191a] ↓ ReinforcementLearningCore v0.5.0 ⇒ v0.4.6
  [d607f57d] ↓ ReinforcementLearningZoo v0.2.1 ⇒ v0.1.7

now id like to reinstall back the add ReinforcementLearning@0.7.0 even if POMDP does not support it
i tried updating ReinforcementLearning and removing the pkg that caused the issue:


rm POMDPs
   Updating `~/x/Project.toml`
  [a93abf59] - POMDPs v0.9.1
   Updating `~/x/Manifest.toml`
 [no changes]

(juliaRL) pkg>  add ReinforcementLearning@0.7.0

but i still get errors, is there a way to force install ReinforcementLearning and all its requirements like i did at the beginning when i simply used ‘add ReinforcementLearning.jl’ ?

Just to confirm you want POMDPs@0.9.1 and ReinforcementLearning@0.7.0 to coexist in the same environment? This isn’t really possible, although there are a couploe of things you could do:

  • Have separate environments for the two packages, so you can use ReinforcementLearning at the latest version in its own environment
  • Manually edit the compat bounds of POMDPs to include ReinforcementLearning version 0.7 - this could of course break POMDPs to the extent it relies on things in version 0.6 that changed when ReinforcementLearning was updated (which is what the version bounds are for). If this works you could make a PR to POMDPs to bump the compat bounds for ReinforcementLearning

no i didnt want POMDPs@0.9.1 with ReinforcementLearning@0.7.0 together

i have fixed it the error by removing the POMDP from the manifest as well
