Hello,  
I have been trying to get some packages to run on a cluster. I have set the variable `JULIA_DEPOT_PATH` to a custom folder where I have installed the required packages and my job script looks as follows:

```julia
#==================================================
#PBS -N job_name
#PBS -m abe
#PBS -e <dir_name>
#PBS -o <dir_name>
#PBS -t 0-48
#PBS -l mem=30GB
#PBS -l walltime=2:99:99
#PBS -l nodes=5:ppn=10

export JULIA_DEPOT_PATH=<custom_dir_path>
/dir/julia-1.4.2/bin/julia --machine-file=$PBS_NODEFILE <file_name.jl>

```

In the file, I have specified `using Distributed` and `@everywhere` as required. The problem is as follows: some of the packages load (for ex: `JLD` and `HDF5` load) while other packages do not load (for ex: `ITensor`, `RandomBasedArrays`). I have played around with the order of loading packages and hence notice that only few load while the others do not. Also, I have used `@everywhere using <package_name>` as mentioned in the docs. The error I get is as follows:

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

```

The problem seems to be that the packages are not being loaded on the worker. Any pointers on how to fix this would be helpful. Thanks!

Are you running a particular environment in `file_name.jl`? Could you paste the header file of `file_name.jl`? (i.e. the `@everywhere` and `addprocs` commands)?

It might be that you need to pass in the flag `--project=/path/to/project` to the julia binary

The header file for the file\_name.jl

```julia
using Distributed
@everywhere include("file_1.jl")

```

and `file_1.jl` has the following header

```julia
using Distributed
@everywhere using Printf, HDF5, ITensors
@everywhere using JLD: save
@everywhere include("file_2.jl")
@everywhere include("file_3.jl")

```

`file_2` and `file_3` have one dependency each with no `@everywhere` commands.

Regarding the environment, I am not sure how to set this but previously I was setting `JULIA_DEPOT_PATH` to a custom package directory (where I have all the packages installed) which worked in v1.0.3.

Just a quick update. I got this to work by doing the following in the file `file_name.jl`:

```julia
using Distributed
@everywhere empty!(DEPOT_PATH)
@everywhere push!(DEPOT_PATH, "custom_dir_path")

```

Thanks for the inputs on this!
