I am following this tutorial to learn Julia and the idea is to add a Github repository to Julia:

pkg> add https://github.com/BenLauwens/ThinkJulia.jl

Unfortunately, it outputs a long error:

(v1.1) pkg> add https://github.com/BenLauwens/ThinkJulia.jl
  Updating git-repo `https://github.com/BenLauwens/ThinkJulia.jl`
ERROR: GitError(Code:ERROR, Class:Config, failed to map '--help')

I don't understand why I am getting this error, so I would like to know any solution to this. By the way, I am using Julia 1.1 and I am using Ubuntu 16.04 LTS.

Do you have git installed in your system? Which OS are you running? Have a look at the git website on how to install it for different OS's.

Try running the command Pkg.Status() and see if you find anything meaningful. If you do so, I recommend checking as well the location JULIA_PKGDIR and removing the whole folder/git repo you 're trying to install.

As a last option you can create a new Julia home. In order to do so:

  1. backup of your current home folder
  2. delete your julia home (.julia in Unix-based systems)
  3. run Pkg.init
  4. Copy your old REQUIRE file to your new home
  5. run Pkg.update
  6. copy old packages to the new home as needed

Good luck!

  • I have `git` 2.22.1. By the way, are you sure your instructions are for Julia 1.1? `Pkg.init` doesn't work in Julia 1.1, `JULIA_PKGDIR` is not a thing in Julia 1.1, the command should be `Pkg.status()`. Anyway... I have followed your instructions and I still have the problem. – David Aug 14 '19 at 21:21
  • Which OS are you running? Try `Pkg.update()`. What do you get? – wizofe Aug 14 '19 at 22:19
  • I have Ubuntu 16.04 and after Pkg.update(), I get: ```Cloning default registries into `~/.julia` Cloning registry from "https://github.com/JuliaRegistries/General.git" ERROR: failed to clone from https://github.com/JuliaRegistries/General.git, error: GitError(Code:ERROR, Class:Config, failed to map '--help') ``` – David Aug 14 '19 at 22:49
  • What happens if you try `git clone https://github.com/JuliaRegistries/General.git` from the command line? – wizofe Aug 14 '19 at 23:41
  • Now I understand my problem, it was something related to `git`. I have added my answer to show why. – David Aug 17 '19 at 04:15

Ok, so the problem is related to some configuration with git. If you try:

git clone https://github.com/JuliaRegistries/General.git

it shows an error:

Clonando en 'General'...
fatal: mal valor de config numérica '--help' para 'core.autocrlf': unidad inválida

which translates to: 

Cloning 'General'
fatal: bad numeric config value 'auto' for 'core.autocrlf

Following this answer, I wrote in the terminal:

git config --global --replace-all core.autocrlf false

and problem solved. Now I can add repositories and packages to Julia.

  • I would appreciate if you mark my answer as helpful, as I located the problem in your `git` :) Ta – wizofe Aug 18 '19 at 16:24
  • This command 'git config --global --replace-all core.autocrlf false' worked for me – Vinod Jul 25 '21 at 02:42
