"The system cannot find the file specified" when using releasify

[DavidR91]

When running

squirrel --releasify Updatetest.1.0.0.nupkg

I receive

Looking at the log, it is creating and then copying Updatetest-1.0.0-full.nupkg to a temporary location:

but Updatetest-1.0.0-full.nupkg is never visibly created on disk, and the destination (C:\Users\david.roberts\AppData\Local\SquirrelTemp\tempa) does not exist either

Is there something obvious I'm messing up here? My nupkg has valid metadata and all the standard content (net45, the squirrel DLLs etc.)

This is happening for me on Windows 10 17763.316 (1809)

Have you resolved this issue or is it still ongoing? @DavidR91

[DavidR91]

I never resolved this issue but I haven't tried with any newer version of Squirrel etc.

[Thieum]

@DavidR91 When you experienced this issue, what was the version of Squirrel used?

[DavidR91]

@Thieum yeah I should have checked before saying I would re-test - this was against 1.9.1 which is still latest, so I wouldn't expect anything has changed

[Thieum]

@DavidR91 it's kind of a shot in the dark, but the main dependency in the part of the code that fails is 7zip. We are using version 16.04, but I tried to use the latest version (19.00) available from https://www.7-zip.org/download.html

I tried to replace the version Squirrel is using by the latest, and it still works in my case. This would need further testing to be deemed ready for production, but you could try to replace the exe and the dll of 7-zip by their latest version counterparts, and see if it changes the behavior of Squirrel in your case.

[Thieum]

@DavidR91 if possible, you could list the filenames and the included paths that are supposed to be in the zip from your build folder here. Maybe there's a filename or a path that has something odd that could help us reproduce the issue.

[maximilianschmidt]

did you guys solve this yet? i tried replacing the 7z with version 19, but i still get the same error

[rohitisinhk]

Works by declaring environment variable "SQUIRREL_TEMP" and pointing it to a temporary directory. I didn't dig much into it but seems like a bug in the way it creates temp directory before extracting zip file (i might be wrong)

[ken-sands]

If you build from scratch to modify for your own use rather than using the nuget squirrel package it's missing a bunch of things from your output folder (equivalent of tools in the nuget). I just copied the missing bits over, 7z, wix, candle, light a bunch of dlls. Not sure how many were actually required but it works for me after that... I'd edit the main page to "Squirrel it's like click once, then mess around for a day, then google for two more then start to wish you just built something from scratch... yep it's like pretty much every project on github that you think is gonna save you some time!" The docs are not accurate at least for the latest version but with a bunch of messing about you can get it to work.

That isn't in the docs because it's completely unnecessary and wrong

[ken-sands]

Well the docs as they stand don't work which is why these threads exist with people trying such things. I did say "Not sure how many were actually required but it works for me after that" The obvious thought from the outside is "If it's wrong why are they all those files there in the squirrel release" Either they are there when they shouldn't be in the release or they are missing when building from source right? Unfortunately like most github projects the docs seem to be written from the developers machine where things just work. We've all done it, but start from a clean fresh machine and you get to once again do all those little things you forget along the way, adding a path to the environment here, pulling down some library there. Don't feel offended it's the same everywhere. Even big names like google with pdfium (it takes a hell of a lot of patience to do all the "fixes" needed to get that thing to actually build!) What would be more helpful than your comment above would be to give the necessary and right steps.

Ran into this recently. We can't upgrade right now for various reasons, so we're still on 1.8.0. Setting SQUIRREL_TEMP to C:\Temp worked for us. Hope this might help anyone else that stumbles in here!
