I used thisvideo as a tutorial
this is a similar problem with no solid solution
particular error code: (ImportError: DLL load failed: The specified module could not be found.)
not sure what to refer to if the only problem is that the file cant be found. if that's what this means.

I'm using WSL with docker (with a complex pandoc configuration with latex, python and pandoc-filters) and trying a long command with --filter=filters/the_filter.sh that results in an error:
Error running filter filters/the_filter.sh: ./filters/the_filter.sh: createProcess: runInteractiveProcess: exec: does not exist (No such file or directory)
My filter is a .sh wrapper, mostly to make sure I'm using Python3 (which may not be needed, but I got the hint from here):
#!/bin/sh
python3 filters/the_filter.py $#
Googling the error shows lots of GitHub issues, but no definitive explanation on Stack overflow.
It turns out that my .sh file had Windows line endings: \r\n.
I assume that the system was trying to find /bin/sh\r but the error message is not explaining it.
Correcting the line-endings using dos2unix filters/the_filter.sh, I was able to get rid of the error.
Here are more details of a related problem.
I've been trying for a few hours now solve this problem and I looked everywhere for a solution and I did not find one. I'm trying to run a spec test for my project and I have the following error coming up:
RuntimeError:
Ghostscript not found in your system environment (linux-gnu).
Install it and set the variable RGhost::Config::GS[:path] with the executable.
Example: RGhost::Config::GS[:path]='/path/to/my/gs' #unix-style
RGhost::Config::GS[:path]="C:\\gs\\bin\\gswin32c.exe" #windows-style
And I do try to put RGhost::Config::GS[:path]='/usr/local/bin/gs' and it returns:
bash: RGhost::Config::GS[:path]=/usr/local/bin/gs: No such file or directory
but ghostscript is installed, I did everything (make, sudo make install, etc etc) and when I run gs -v it returns:
GPL Ghostscript 9.26 (2018-11-20)
Copyright (C) 2018 Artifex Software, Inc. All rights reserved.
When I use the user interface and search for "gs" in the "Files" application, it is found in /home/marcelle/projects/ghostscript-9.26/bin/gs and I also tried:
RGhost::Config::GS[:path]='/home/marcelle/projects/ghostscript-9.26/bin/gs'
and it returns the same error:
bash: RGhost::Config::GS[:path]=/home/marcelle/projects/ghostscript-9.26/bin/gs: No such file or directory
I also tried to delete ghostscript from my notebook with autoremove and purge and installed it again using what I mentioned before (./configure, make, sudo make install), restarted the notebook, the terminal and nothing.
PS: I'm using Ubuntu 20.04.
I managed to figure out a solution. Looking for the code for the Rghost, what I saw in its spec is that the path expected was different than the path the ghostscript really is.
When I run whereis or which on my terminal, it returns:
which gs
/usr/local/bin/gs
So I was trying to point to this path. But seeing the spec test for Rghost which I found on github for Rghost, we can see that it expects /usr/bin/gs:
it 'should detect linux env properly' do
RbConfig::CONFIG.should_receive(:[]).twice.with('host_os').and_return('linux')
File.should_receive(:exists?).with('/usr/bin/gs').and_return(true)
RGhost::Config.config_platform
RGhost::Config::GS[:path].should == '/usr/bin/gs'
end
So it expects /usr/bin and not /usr/local/bin.
Then I just copied to that path and the spec ran with no problems anymore:
sudo cp /usr/local/bin/gs /usr/bin
I've no experience with Ruby at all, but I also got this error when using asciidoctor, which uses rghost for the PDF generation.
The command RGhost::Config::GS[:path]='/path/to/my/gs' mentioned in the error is not a shell command, which is why bash couldn't handle it. However, to me it wasn't immediately clear what to do with this command either. I expected an easy way to set this variable somewhere, but couldn't find it.
What worked for me was searching the rghost.rb file, which is where this variable is set and can be changed. In Windows, it was located in C:\Ruby30-x64\lib\ruby\gems\3.0.0\gems\rghost-0.9.7\lib\rghost.rb.
In this file, I added the following line, which solved the problem:
RGhost::Config::GS[:path]="C:\\Program Files\\gs\\gs9.55.0\\bin\\gswin64c.exe"
NB: the mentioned paths can be different for everyone, so make sure to use that paths that are valid for your system.
I'm new to data science and wanted to do a little tutorial, which requires airflow, among other things. I installed it on windows using git bash in VS Code. I tried running it but it had a problem not being able to load the sqlite3 import
command (module not found error). I figured out that if I added the directory of sqlite3.py to the path, it would run, but now it gives me a similar error: pwd module not found from daemon.py
File "C:\ProgramData\Anaconda3\lib\site-packages\daemon\daemon.py", line 18, in <module>
import pwd
ModuleNotFoundError: No module named 'pwd'
Strange to me that it can't find pwd. Obviously pwd works in both git bash and powershell natively. It seems like a basic universal command. I'd love to learn more about what's going on. I don't want to have to end up adding 100 things to path just to get this program to run. I'd love any insights anyone can provide.
PS I'm using Anaconda.
it's seems to be the side effects of Spawning new Python Daemons .
You likely can fix this by downgrading the Python-Daemon :
pip install python-daemon==2.1.2
I needed to use Meep for one of my simulations and am trying to figure out how to do it. I installed Meep on Cygwin platform as detailed in this website:
http://nikodem.blogspot.com/2015/12/installing-meep-under-windows.html
After installation, I open the cygwin bash shell and type meep, which gives me the Meep prompt : meep>
But whenever I try to run some example files provided along with the installation and stored in C:\meep\meep-1.3\examples\, eg:
meep> bend-flux.ctl
I get the same error :
ERROR: Unbound variable: bend-flux.ctl
ABORT: (unbound-variable)
Any help to figure out how to run the .ctl files would be really helpful.
I'm just getting into ruby and am trying to execute a walkthrough from Sam Ruby's Agile web development.
I've created a directory using mkdir work
Next i'm instructed to open a terminal and type rubys> cd work
The error I'm getting reads:
No command 'rubys' found, did you mean:
Command 'ruby' from package 'ruby' (main)
rubys: command not found
Can anyone inform me of what I'm doing wrong?
I've also tried changing from ~ to the work directory before entering my command.
In this book, rubys> is a command prompt, much like you have C:\> in the Windows terminal.
Ignore that first bit and everything should start working.
I guess you're doing it wrong.
mkdir work
creates a directory called "work". It has nothing to do with Ruby.
cd work
will then change into that directory. Forget about the rubys>.
