Hi,

I’m trying to use parallel processing on Julia 1.0.1 and found the following issue: the new worker is not able to find packages I already installed. Please help me do this in the right way.

In the example below, I first showed that “using DataFrames” works fine, since DataFrames has been installed. But after adding a process, “@everywhere using DataFrames” fails because worker 2 (the newly added worker) cannot find DataFrames.

```julia
julia> using DataFrames

julia> using Distributed

julia> addprocs(1)
1-element Array{Int64,1}:
 2

julia> @everywhere using DataFrames
ERROR: On worker 2:
ArgumentError: Package DataFrames not found in current path:
- Run `import Pkg; Pkg.add("DataFrames")` to install the DataFrames package.

Are you using a different environment than the default (e.g. `] activate .` or starting with `julia --project`)? If so see [this discussion](https://discourse.julialang.org/t/packages-and-workers/14072).

Hi I am seeing the same error with exactly the same usage as the one of @Zhong_Pan, and so would like to revive this topic.

The simplest code to demonstrate the error is:

```julia
using Distributed
addprocs(2)
@everywhere using DataFrames

```

I’m running on JuliaPro 1.1.1 (tried the latest 1.2 and it won’t help) on Windows 8.

It’s not a different environment. And the [discussion](https://discourse.julialang.org/t/packages-and-workers/14072) you mentioned seems to concern only user’s own package but not a curated package such as DataFrames.

I tried a lot of things and none of them seems working. I’m under the impression that it is because packages in v1.0+ are now installed “locally” on userprofile path instead of a global C: drive location.

First, obviously I’ve installed DataFrames and this line of code will run okay:

```julia
using DataFrames

```

Then, instead of DataFrames, a standard package such as HTTP will work:

```julia
@everywhere using HTTP

```

Reading through past topics but don’t seem to have find a solution.

[This discussion](https://discourse.julialang.org/t/load-modules-in-several-workers/17521/19) suggests the installation wasn’t clean but I have already uninstalled and re-installed several times.

[This one](https://discourse.julialang.org/t/workers-do-not-find-packages-in-spite-of-everywhere-and-pkg-activate-commands/23441/2) seems to suggest JuliaPro won’t work with distribution - I hope it’s not true and there is a solution.
