Pkg.build("Gurobi") problem for Gurobi in conda environment #316
Comments

I've never tried Gurobi and Anaconda. Just install it normally. You need the following structure |
|
I need to run Julia w/ Gurobi on a remote server. What do you mean by 'install it normally'? And by 'structure', do you mean: '/home/changd/anaconda3/envs/virtual_env/bin/lib/gurobi90.so' |
Yes. Note that Gurobi.jl isn't officially supported by Gurobi. |
|
Ok. Is this your suggestion for how to proceed (on a remote server):
|
|
Yes, that seems sensible. Gurobi support may have a better way to do this; worth checking with them. |
|
I will check that out with Gurobi support, thanks. |
|
I updated my Gurobi installation, the Gurobi Python API appears to be functioning properly. Most likely there is not an issue on Gurobi's end. However, now I get the following error message (see below) for Pkg.build("Gurobi"). I then tried Pkg.build("CodecZlib") but get a very similar error message. Building CodecZlib ─→ |
Did you follow this instruction? |
|
I installed busybox but I'm still getting the same error message. Message said "Install one and ensure it is available on the path." What "path" is being referred to // is this the most probable issue or is something else likely the problem? |
|
What machine are you trying to install this on? Its linux but it doesn't have curl or tar? The http://www.linfo.org/path_env_var.html |
|
This is a linux machine. Presumably it should have curl or tar but somehow I'm getting the above error message. Where should I be installing busybox (or some similar counterpart)? FYI: echo $PATH: I installed busybox in "/home/changd" which appears to be problematic. |
|
Try ENV["PATH"] = ENV["PATH"] * ":/home/changd"
import Pkg
Pkg.build("Gurobi")Or move busy box into Do you really not have curl or tar in |
|
I checked ‘home/changd/anaconda3/bin’, where I found curl but not tar. I do not have a folder of the form ‘home/changd/bin’.. (I’m working on a server) I will check this with the sysadmin. I updated ENV["PATH"] = ENV["PATH"] * ":/home/changd/anaconda3/bin" I also moved busy box into /home/changd/anaconda3/bin. The original error message was: Now a download engine was found (curl), but not a compression engine (they did not find busybox). I wondering whether it's because the busybox folder under /home/changd/anaconda3/bin is titled 'busybox-1.31.1' and therefore it was not found. |
|
Your sysadmin can help you with this. It seems like it's a non-standard setup. They'll know how to modify your path to get curl and tar, so this isn't a Julia or Gurobi.jl issue. |

Pkg.add("Gurobi") and using Gurobi are working now after some fixes. It appears the issue was cross contamination of the anaconda environment. |
I'm having trouble with Pkg.build("Gurobi"). Tried changing ["GUROBI_HOME"] to installation location but still does not work, so I'm wondering what possible issues are. Details:
I installed Gurobi using command line in a conda environment by following Steps 2-3 here: https://www.gurobi.com/gurobi-and-anaconda-for-linux/
Gurobi 9.0.2, Julia 1.0.3
The files gurobi_cl, gurobi.env, gurobi.sh (corresponds to Gurobi installation right?) are in: /home/changd/anaconda3/envs/virtual_env/bin/
So I set ["GUROBI_HOME"] = /home/changd/anaconda3/envs/virtual_env/bin/
gurobi.lic is in /home/changd/.
I think try "import Pkg" followed by "Pkg.build("Gurobi")", then receive the following error message:
