Trouble with runing an app which uses PythonCall

[YuliyaCl]

Hello! I've an error when i'm trying to run an created app which uses PythonCall.

Code for MWE is published here: https://github.com/YuliyaCl/PythonCall_tst.jl.

To create an app run file deploy/compile_app.sh . Tests and building proccess run correctly but when I'm runing PythonCall_tst.exe in cmd, an error occurs:

fatal: error thrown and no exception handler available.
InitError(mod=:C, error=ErrorException("no environment in the LOAD_PATH depends on CondaPkg"))

Addition information about the issue.

To reproduce the error itself you may compile an app and run the function:

using CondaPkg
PythonCallCompiled\\share\\julia\\Project.toml._resolve_top_env( [ pathToTheProjectToml ] )

pathToTheProjectToml - it's a path to Project.toml file inside folder with compiled app - "....\share\julia\Project.toml"

Also the difference in output occurs when run Base.manifest_uuid_path() with two Project files (to reproduce the error change the paths to yours)

pkg = Base.PkgId(Base.UUID("992eb4ea-22a4-4c89-a5bb-47a3300528ab"), "CondaPkg")
env_raw = "C:\\Users\\yzh\\.julia\\dev\\PythonCall_tst\\Project.toml" #inside the repo 
env_compiled = "C:\\Users\\yzh\\.julia\\dev\\PythonCall_tst\\PythonCallCompiled\\share\\julia\\Project.toml" #inside the compiled app folder

out1 = Base.manifest_uuid_path(env_raw, pkg) # -> "C:\\Users\\yzh\\.julia\\dev\\CondaPkg" 
out2 = Base.manifest_uuid_path(env_compiled, pkg)  # -> nothing

Place in CondaPkg.jl where this trouble occurs: https://github.com/cjdoris/CondaPkg.jl/blob/78f2a639b5bfb88920c7021c568e39d87c112950/src/resolve.jl#L9

UPD: I thought it couldn't find Manifest-file in Project.toml. If copy-paste Manifest.toml (where in [[deps.CondaPkg]] parametr path is equal to local path to dev/CondaPkg.jl) to the "...PythonCallCompiled\share\julia" the error ErrorException("no environment in the LOAD_PATH depends on CondaPkg") disappears and another one occurs:

InitError(mod=:C, error=Base.IOError(msg="readdir("C:\\Users\\yzh\\.julia\\dev\\PythonCall_tst\\PythonCallCompiled\\share\\julia\\stdlib\\v1.7"): no such file or directory (ENOENT)", code=-4058)) 

If copy-paste Manifest-file where [[deps.CondaPkg]] instead of path has git-tree-sha1 the error in issue still exist.

I've also taken a bit of a look.

You can work around the "no environment in the LOAD_PATH depends on CondaPkg" error by changing _resolve_top_env(load_path) so that the if is_condapkg || depends_on_condapkg is just if true (to always use the top environment). It was failing because it couldn't find a Manifest.toml containing CondaPkg.

But this surfaces another error

InitError(mod=:C, error=Pkg.Types.PkgError(msg="expected package `CondaPkg [992eb4ea]` to exist in the manifest (use `resolve` to populate the manifest)"))

Again, this is because there is no Manifest.toml.

Maybe this is a bug in PackageCompiler, erroneously not outputting a Manifest.toml? If you make a trivial app with no dependencies, does it create a Manifest.toml?

[YuliyaCl]

Thanks for the answer! I've compiled an app without any dependencies. Manifest.toml wasn't created

[YuliyaCl]

Also i've also created an app with only Statistics.jl in deps to check PackageCompiler. Manifest.toml wasn't created but everithing worked correctly.

[YuliyaCl]

The problem is in CondaPkg. I've compile an app with only CondaPkg in the deps. It failed at line CondaPkg.status()...

So redirect this issue to CondaPkg.jl ..
