I just installed JuliaPro. I have Juno up and running and have executed some basic code.

I am, however, unable to install any packages. Instead I keep getting the error:

ERROR: IOError: unlink: permission denied (EACCES)

There is a file titled “auth.toml” located in .juliapro/JuliaPro\_v1.3.1-1/servers/pkg.juliacomputing.com/ so I think I have the requisite token.

Any help or guidance would be greatly appreciated.

Thanks,

DS

Here’s the problem in its entirety:

Hey donkeysaddle,  
I had the same problem after upgrading from JuliaPro 1.0 to 1.3 I installed the 1.3 version before deinstalling the 1.0 version. After experiencing the same problem I deleted both and did a clean reinstall of JuliaPro 1.3 and now it seems to work fine. Had to reinstall all the Packages though.  
Hope they put out a nice documentation about upgrading Julia, without having to reinstall all the packages. (At least I wasn’t able to find it)  
Hope that helps  
Best,  
Merit

Hey meritwagner,

Thanks for the response. I did see that I should uninstall all versions of JuliaPro I might have on my computer, however, I am a first time JuliaPro user. I do have version 1.3 of Julia and Juno. But from what I read they are not incompatible.

But maybe that’s where I am running into problems. What do you think?

Thanks,

DS

This is a sometimes expressed bug in the mac installer. To fix, you could `chown` the `~/.juliapro/JuliaPro_v1.3.1-1/registries/JuliaPro/.git` folder to your user (it’ll probably be owned by root)

Sorry about that, it’ll be fixed by a new release soon. But for now, this workaround should be sufficient.

Thanks!

just to be clear, which user are we talking about here?

Appreciate it, Avik.

</div>

just wanted to give a follow up, avik’s solution appears to have worked! Thanks, avik!

There was one thing that hung me up - I had to change ownership not just of the .git folder but all the sub folders it contained.

Thanks again, avik!

For those w/o much experience:

in the terminal

chown -R username ~/.juliapro/JuliaPro\_v1.3.1-1/registries/JuliaPro/.git

if this doesn’t work try:

sudo chown -R username ~/.juliapro/JuliaPro\_v1.3.1-1/registries/JuliaPro/.git
