Candidates function `helm-rg--make-process' should run a process

[NoahDragon]

I got the issue while running emacs on windows. Recently change ag to rg, but got this message while using M-x "helm-projectile-rg" under a project file. Does anyone happen know the cause?

[yeliu84]

@NoahDragon I have this issue when my working directory isn't the project root, if I use M-d to search from project root, this error message goes away.

If your symptom is the same, the issue is from helm-projectile, and there is an issue opened for it. In the mean time, you can try to set helm-rg-default-directory to 'git-root as a workaround.

Using the workaround suggested by @jaux I'm able to get into a *helm-rg* process buffer using helm-projectile-rg regardless of working directory.

However, I'm still running into this issue when trying to actually search anything in the process buffer; when typing the required 2 chars I start getting blasted with the following error:

Error running timer: (error "Candidates function `helm-rg--make-process` should run a process")

Config:

(use-package helm-rg
  :config (setq helm-rg-default-directory 'git-root))

(use-package helm-projectile)

I get this error after using use-package, haven't figured out why.

I started seeing this error right after I reinstalled my system

[kuba-orlik]

After further investigation it turns out I had the helm-rg-ripgrep-executable variable set to '/usr/bin/rg instead of /usr/bin/rg 🤦‍♂️

@kuba-orlik I had this issue too after customizing the path in helm-rg-ripgrep-variable. Now it's back to "normal" :).

helm-rg-ripgrep-variable.

There is no such variable. If you meant: helm-rg-ripgrep-executable it still doesn't work for me. The problem is that it doesn't work if there is no .git in the hierarchy. This should not be the case.

helm-rg-ripgrep-variable.

Yes, you are right. I misspelled the variable name.
I understand for you it works only if it's a git folder.

[rileyrg]

Does it work for you if no .git directory?

Yes, it does.

[rileyrg]

Thanks for your reply! You're sure there's no git repo in a parent? I have all latest melpa updates. I don't think I'm doing anything untoward : my-projectile-grep https://github.com/rileyrg/Emacs-Customisations/blob/master/config.org#projectile

Yes, I am very, very sure. There is no GIT repo in the folder where I call M-x helm-projectile-rg.
Very. Very. Sure.

[rileyrg]

Not in the folder. A parent. Just to be sure 🙂

Not in the children, not in the parent, not in the grandparent. :)

Note that this message also appears when rg cannot be found, so there's a good chance at least some of these comments come from a misconfiguration - check if you can run rg with M-x eshell.

Maybe a more readable error message when the rg binary isn't in the path would be handy :)

[leejh903]

In my case, I did not installed rg. So I installed rg using command sudo apt install ripgrep and I solved it

[asmodeus812]

Same issue here with helm enabled when i hit SPC s p to do a project wide search nothing happens i get the same error - helm-get-candidates: Candidates function ‘helm-rg--make-process’ should run a process. I am on windows i have rg installed and env path poining to it. I can access it from cmd or eshell by simply typing rg

Note that the helm rg executable variable points to "c:/ProgramData/chocolatey/bin/rg.exe"
But i have not installed rg with choco. This directory does contain an rg exe which when started does open rg indeed. But the rg i installed i put in program files and that is where the env path variable points to.

[garvinguan]

@willnevillain Not sure if this fixes your issue but I ran into the same thing when I had set helm-rg-ripgrep-executable like so

(setq helm-rg-ripgrep-executable '/usr/local/bin/rg)

setting helm-rg-ripgrep-executable like this fixed the issue for me

(setq helm-rg-ripgrep-executable "/usr/local/bin/rg")

[arichiardi]

I also use use-package and in my case I noticed the helm-rg code is evaluated at a moment when the PATH has not yet been set (via exec-path-from-shell) and that results in an empty helm-rg-ripgrep-executable.

Just wanted to highlight that on some systems you need to make sure the exec-path is set correctly before helm-rg defines its defcustom.

One tweak worth considering to helm-rg is to run (and store) (executable-find "rg") when the command is launched the first time...
