Can someone please help me understand this error message?  
On my Sytem (Windows10), any call to ‘PkgDev.publish()’ fails with this error message.

Windows10 doesn’t ship `curl`, you should manually install it and add it to `Path`.

Thanks. I am using JuliaPro (v0.5.1.1\_build-43) and made the apparently wrong assumption that in the distribution for Windows such tools are already integrated. After all the ‘publish()’ command is a basic one.

> Hello everyone, I want to make a quick announcement about the JuliaPro distribution that we at Julia Computing have put together and made available for download. The developer edition is free, and we also have an enterprise edition with paid support. It has taken us a long time to put together a distribution including Julia, Juno, and a variety of precompiled packages in one single download. We want to make Julia much easier for new users of Julia, and this is one small step in that direction. …

I can’t speak about JuliaPro - never used it - but with ‘regular’ Julia on Windows it does matter what terminal you launch from. If I launch from the regular Windows command line and type `;curl` I get that error. If I launch from git bash (which has some tools built in) and type `;curl` I get `curl: try 'curl --help' or 'curl --manual' for more information`.

It might be worth looking into native Julia alternatives to curl: HTTP.jl for example

It is kind of funny I found this post because some tests on HTTP.jl are failing on WIndows because it can’t find `curl` 😃

Any idea how to get AppVeyor tests to pass if the tests depends on `curl`? Tests are passing on Travis now so I’m trying to get AppVeyor to pass as well. Thanks!

It might be helpful if you show us the tests (reduced to some minimal form) which fail.

Thanks @leiteiro. I think I got it. Trying now 🙏. I think I can install `curl` using WinRPM. Will report back 😊

btw; [Build Environment | AppVeyor](https://www.appveyor.com/docs/build-environment/#build-worker-images) lists curl as pre-installed

The test launches a server on a random port, in this case 8661, runs the below command:

```julia
run(`bash -c 'curl -v -s http://127.0.0.1:8661/ > tmpout 2>&1'`)

```

It errors with the following message:

```julia
  Got an exception of type Base.UVError outside of a @test
  could not spawn `bash -c 'curl -v -s http://127.0.0.1:8200/ > tmpout 2>&1'`: no such file or directory (ENOENT)

```

I thought it was `curl`, but now I think the problem is the `bash` statement. It doesn’t work on Windows. Any idea?

It might make sense to read a little bit into appveyor doc and forums [Support | AppVeyor](https://www.appveyor.com/support/#forums-and-support-tickets)  
as i have the feeling you are not the only one to test with a local server (you might be one of the few to use julia).
