Hi guys, sorry to bother you but each time i try to add Nettle, i got an error :

(v1.2) pkg> add Nettle Resolving package versions... ERROR: Unsatisfiable requirements detected for package BinDeps [9e28174c]: BinDeps [9e28174c] log: ├─possible versions are: [0.7.0, 0.8.9-0.8.10, 1.0.0-1.0.1] or uninstalled ├─restricted by compatibility requirements with Nettle [49dea1ee] to versions: [0.7.0, 0.8.9-0.8.10] │ └─Nettle [49dea1ee] log: │ ├─possible versions are: [0.4.0, 0.5.0] or uninstalled │ ├─restricted to versions * by an explicit requirement, leaving only versions [0.4.0, 0.5.0] │ └─restricted by julia compatibility requirements to versions: 0.4.0 or uninstalled, leaving only versions: 0.4.0 └─restricted by compatibility requirements with Compat [34da2185] to versions: 1.0.0-1.0.1 or uninstalled — no versions left └─Compat [34da2185] log: ├─possible versions are: [1.0.0-1.0.1, 1.1.0, 1.2.0, 1.3.0, 1.4.0, 1.5.0-1.5.1, 2.0.0, 2.1.0, 2.2.0, 3.0.0, 3.1.0, 3.2.0, 3.3.0-3.3.1, 3.4.0, 3.5.0, 3.6.0, 3.7.0, 3.8.0, 3.9.0-3.9.1, 3.10.0] or uninstalled └─restricted to versions 3.10.0 by an explicit requirement, leaving only versions 3.10.0

Even if i specifie a version, i got an error :

My version of Julia :

Hope you can help me, and thank you in advance for your answer !

You have a pkg resolver conflict; this means that your package versions are incompatible. It looks like because you are using Julia 1.2, you cannot install the latest version of Nettle (which is 0.5.0), and the older version of Nettle requires a version of BinDeps that conflicts with something else.

My advice is to upgrade to Julia 1.4; the newer version of Nettle does not require BinDeps at all.

I can't change my julia version (the project needs to be in Julia 1.2) but i will check if there is a way to avoid those conflicts, thx !
