Mlflow not running on machine

Please I am trying to run mlflow code in R after having installed it. However, after loading the library with library(mlflow) and I run mlflow_log_params("foo",42) I get the error message below printed in my console:
Error in rethrow_call(c_processx_exec, command, c(command, args), pty, :
Command 'C:/Users/IFEANYI/AppData/Local/r-miniconda/envs/r-mlflow-1.19.0/mlflow' not found #win/processx.c:982 (processx_exec)
I also get the same error message when I run mlflow_ui(). Please was there something I ought to have done during installation failure of which is affecting its functionality? Do I need to install and load the processx library in order for mlflow to run on my Windows10 machine? I really hope I can get advice to help me because I want to use mlflow in my machine learning projects. Thanks in advance of your generous help.
The error should disappear when setting MLFLOW_BIN system variable (Windows) to mlflow cli executable : "....conda\envs\r-mlflow-1.24.0\Scripts\mlflow.exe".
If it works please mark the problem as resolved.
Unfortunately, you will get next error "Error in wait_for(function() mlflow_rest("experiments", "list", client = client)" for which I cannot find the solution

Debugging problem when knitting from r markdown to pdf

I've downloaded miktex, tinytex and ghostscript and tried changing the path since the problem seems to be in the path. So far nothing has helped me and I would appreciate some help:
This is my error message:
Error: LaTeX failed to compile Uebungsblatt1_MAT183.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See Uebungsblatt1_MAT183.log for more info.
In addition: Warning message:
In has_crop_tools() :
Tool(s) not installed or not in PATH: ghostcript
-> As a result, figure cropping will be disabled.
Execution halted
Any help or try to troubleshoot would be appreciated. Thank you
I have figured this out for myself by now: what I did was that I first uninstalled MikTex and tinytex because they apparently were clashing somehow. Then I reinstalled tinytex - this time typing it directly into the console instead of using the installing tool from R - so I typed everything at a time and executed it. It had me restart R and updated some files then too. Since then it has worked flawlessly. Also, I did the same on my other computer (MacBook) where it didn't work so chances are pretty good that that might solve that same problem for someone else out there. Thanks to everybody who tried helping and improved the question or sent responses.
Which code you tried to compile?
Sometimes this error rise when a letter is missed in the \begin function. If you tried to compile an array, do not forget to use the same letters as rows you need.
Example:
$$|x|=\left\{\begin{array}{ll} -x & \text{si }x\le 0\\ x & \text{si }x\ge 0 \end{array}\right.$$
