ERROR: The following package names could not be resolved: * DataFrames (not found in project, manifest or registry) Please specify by known name=uuid.

Hi! I'm new to Julia and this is my first issue ever. First of all, I'd like to say that I encountered this problem as I installed Julia-Pro (specifically Current stable release v1.5.4-1), which led to the following problem. The thing is, that before I installed Julia-Pro I could install packages just fine.

I tried to install a package like this: (the issue is not in the DataFrames package, I tried a lot of packages and non of them managed to get installed)

Pkg.add("DataFrames")

and received this error:

ERROR: The following package names could not be resolved: * DataFrames (not found in project, manifest or registry) Please specify by known name=uuid.

I know, that there are different ways of fixing the problem, like on this stack overflow question. Pity, but I could fix the problem anyhow with any commands.

But I wanted to point out my solution, which I found:

As you install Julia-Pro, you are asked to enter a url from where packages will be installed or you can leave the field blank, which they say means "use default registry". On my first run with Julia-Pro I left that field blank and had that errors. Then I deleted it and installed again. On my second install, I copied an example url from that exact popup window and entered in the field. After that everything worked fine.

My guess is that this is something to do with Julia-Pro, not Julia itself and I just wanted to point such issue in case anyone finds it helpful

Hello,

This issue is not related to Julia, you can contact juliapro@juliacomputing.com for issues related to JuliaPro in future. Your original issue might have been caused due to lack of or corrupted General registry, if you're still facing this issue, I would suggest you to manually delete following folder

If you're using Mac or Linux then delete

~/.julia/registries/General

In case of Windows

<HOME-DIRECTORY>\.julia\registries\General

Once General registry is deleted, you can execute following command in JuliaPro REPL to fix this issue

Pkg.Registry.add(Pkg.RegistrySpec(url = "$(Pkg.pkg_server())/registry/General", uuid = "23338594-aafe-5451-b93e-139f81909106"))

@bmharsha thank you so much! I recently encountered this error here : ERROR: The following package names could not be resolved: * CSV (not found in project, manifest or registry) and your solution worked for me!

@bmharsha You saved my day. Had the exact issue with JuliaPro and your fix solved it.

I had the same problem and followed the procedure. After deleting the <>.julia\registries\General directory, when running the "Pkg.Registry.Add(..." command on Julia REPL I am getting the following error:
"ERROR: Could not determine command" - maybe I am doing something wrong but I really don't know what is wrong b/c I copied the exact command.

I am using Julia 1.5.3, does it has something to do with this error?

Thank you.

It seems you are in the Pkg REPL mode. You should execute that in the normal Julia mode. Press Ctrl+C in the Pkg REPL to go back to the Julia REPL.

Thank you for the update.
I installed the last version 1.6.2 with Anaconda to use Jupyter Notebook, apparently the issue was resolved as I am able to install packages inside the notebook. :)
