Hello. I am trying to run my julia project on my school’s cluster. They have pre installed a Julia v1.7.1 Linux x86 binary. Adding Plots in the Pkg interface causes pre-compilation to fail:
```julia
Precompiling project...
✗ Plots
19 dependencies successfully precompiled in 46 seconds (114 already precompiled)
1 dependency errored. To see a full report either run `import Pkg; Pkg.precompile()` or load the package
```
Running Pkg.precompile() results in no output. If I then import Plots into my current session, I end up with the following error:
```julia
julia> using Plots
ERROR: InitError: could not load library "/n/home06/dochang/.julia/artifacts/303fe895f57042ea41055187ec4af6322989b5cc/lib/libgobject-2.0.so"

I get a completely different error if I try importing again in the same session:
```julia

Importing a third time just results in the same error as the second. I’ve tried changing my `.julia/config/startup.jl` to include:
```julia
ENV["LD_LIBRARY_PATH"] = ""
```
since I’ve seen this given as a solution in [another post](https://discourse.julialang.org/t/failed-to-precompile-plots-due-to-initerror-in-libgobject-2-0-so-undefined-symbol-g-pattern-spec-copy/88900); but this failed to resolve my problem.
Does anyone know how to resolve this? Help would be greatly appreciated.

That’s not what [I suggested](https://discourse.julialang.org/t/failed-to-precompile-plots-due-to-initerror-in-libgobject-2-0-so-undefined-symbol-g-pattern-spec-copy/88900/8). My suggestion was to set the environment variable _ **before** _ starting the Julia process, setting the environment variable inside the Julia process has no effect with regards to loading libraries in-process.

Thanks! I misunderstood. That seemed to have fixed my issue.
