I’m encountering precompilation failures with a package that uses TextAnalysis.jl  
See minimal example here: [https://github.com/AsafManela/TextAnalysisUser.jl](https://github.com/AsafManela/TextAnalysisUser.jl)  
As you can see below, whenever I call “using TextAnalysisUser” precompilation fails.  
The package usually still works, but loading it is much too slow.  
Any ideas?

What happens if you just `pkg> activate` the environment for this package, then execute

```julia
pkg> status
# and
julia> using TextAnalysis

```

? In particular, are you using a non-standard/forked version of `TextAnalysis`? Does it otherwise load cleanly?

That is what I am doing in the code snippet above (not sure why it is in red).  
As it shows, I’m using current master from the original TextAnalysis.jl:

```julia
[a2db99b7] TextAnalysis v0.5.0+ #master (https://github.com/JuliaText/TextAnalysis.jl.git)

```

Not quite, I am asking for `using TextAnalysis`.

Sorry, missed that one.  
For some reason, using TextAnalysis first works, as you can see below. But new julia sessions still recompile

```julia
(TextAnalysisUser) pkg> st
Project TextAnalysisUser v0.1.0
    Status `~/.julia/dev/TextAnalysisUser/Project.toml`
  [a2db99b7] TextAnalysis v0.5.0+ #master (https://github.com/JuliaText/TextAnalysis.jl.git)

julia> 

```

New session:

```julia
(v1.0) pkg> activate .

```

Is this how caching is supposed to work?

The first two things I would try is

1. making sure file/directory permissions are OK,

2. remove the whole compiled cache (for all packages).

Thanks for the tips! I removed the entire .julia/compiled/v1.0 dir.  
First time everything precompiles fine. But second time I get the same failure:

```julia
