Dear Julia users,

I am so desperate, since last Friday I have been having troubles with almost all the packages that I wanted to install.

First of all I was triying to update my packages and I get the following error.

```julia

Pkg.update()
INFO: Updating METADATA...
INFO: Updating BinaryProvider master...
INFO: Computing changes...
ERROR: resolve is unable to satisfy package requirements.
  The problem was detected when trying to find a feasible version
  for package Compat.
  However, this only means that package Compat is involved in an
  unsatisfiable or difficult dependency relation, and the root of
  the problem may be elsewhere

```

Secondly, I was trying to install the Gurobi Solver and I got:

```julia
Pkg.add("Gurobi")
ERROR: resolve is unable to satisfy package requirements.
  The problem was detected when trying to find a feasible version
  for package Compat.
  However, this only means that package Compat is involved in an
  unsatisfiable or difficult dependency relation, and the root of
  the problem may be elsewhere.

```

Thirdly with the Juniper Package:

```julia
Pkg.add("Juniper")
ERROR: Unsatisfiable requirements detected for package MathProgBase:

└─version range [0.6.0,0.7.0-) required by package Juniper, whose allowed version range is [0.0.0-,∞

```

And also when I am triying to build the Ipopt package I get:

```julia

[BUILD ERRORS]=======================
WARNING: Ipopt had build errors.

 - packages with build errors remain installed in /home/user/.julia/v6.0
 - build the package(s) and all dependencies with `Pkg.build("Ipopt")`
 - build a single package by running its `deps/build.jl` script

================================
INFO: Package database updated
INFO: METADATA is out-of-date — you may not have the latest version of Ipopt

```

Someone knows what is the problem? It is insane, I have never had so much troubles for installing packages in any environment.

No, I am using v6.2.2 mkl. It was a mistake, I had it in my wallpaper a copy of another github error.

This is JuliaPro, right? A number of people have been having package update issues with it lately, because JuliaPro has a pretty restricted set of required packages and versions. You might want to try downloading the plain command line Julia from [Download Julia](https://julialang.org/downloads/) to see if that resolves the package issues.
