nimforum mirror - nim cannot reference libraries installed with nimble.

I use Windows 10. The version of nim is 0.2. 2.

I would like to use jester. So I ran "nimble install jester" at the command prompt.

The installation was successful and no errors occurred. However, an error occurs in "import jester".


import jester

routes:
  get "/":
    resp h1("Hello world")


D:\project\nim>nim c -r main.nim
Hint: used config file 'F:\scoop\apps\nim\current\config\nim.cfg' [Conf]
Hint: system [Processing]
Hint: widestrs [Processing]
Hint: io [Processing]
Hint: main [Processing]
D:\project\nim\main.nim(1, 8) Error: cannot open file: jester

Why is this? If anyone knows, please let me know the solution. Thank you in advance.

You probably haven't added nimble packages dir to your PATH. Also, you should install Nim with choose I'm. Scoop is awesome, but choosenim is the way to go these days.

Thank you for your reply, moigagoo. You said, "Select I'm" What is "I'm"?

And I added the path of nimble's package folder "System environment variables" to "Path" of "D: nimble pkgs". The same error occurred.

I think moigagoo meant choosenim https://github.com/dom96/choosenim

on Windows you have to add two paths to your system setting; Nim install path and nimble storage path.
for me it's :
C:\Programs\nim-0.20.0_x64\bin
D:\Users\ffred\.nimble\bin

I set those paths before using "nimble install.." command. don't know where it goes if you don't set the path before.

Whoaa..!! really painful to format a so simple message here..!?

finish.exe can also set environment variables for you...

if you install Nim using choosenim then all you need to do is add one path: %USERPROFILE%\.nimble\bin (not sure using that USERPROFILE variable will work, but if not just expand it to whatever it is on your system).

Apart from finish.exe, did you add a requires "jester" line in your .nimble file? For me, that was what I was missing the first time when I tried to use a nimble package... didn't seem to be clearly explained in the most intuitive places I checked...

Thank you everyone for an answer. I uninstalled and reinstalled nim and nimble. However, the problem has not been solved. How do I view the path to the location of nimble packages from the command prompt? I would like to know where nim is going to see the package.

I tried choosenim( https://github.com/dom96/choosenim/releases ) and it doesn't install nim.

First, I downloaded "hoosenim 386 .0 _ windows _ i -0.4 .zip" from the choosenim release page. Answer zip and run runme.bat.

There were no particular errors and processing ended. Thereafter, running "nim -v" and "choosenim" at the command prompt also displays "Not recognized as an internal or external command, operable program, or batch file.".

Did you follow Choosenim's instructions to modify your PATH?

nnahito (orginal) [2019-10-15T02:40:07+02:00] view original

Thank you for your reply!

Setting PATH now allows all choosenim, nim and nimble commands to be used. Thank you!

However, you still cannot call modules like jester from nim. :_(
