I've followed the directions here to build html documentation https://code.ros.org/trac/opencv/browser/trunk/opencv/doc/README.txt (actually my local copy that came with OpenCV 2.2, but they are the same), but I get this error after running sh buildall:
parsing

IOError: [Errno 2] No such file or directory: 'parse-cache/c83e178b805f6b01ff8d55cda4bd4a29'
The pdf file built fine but I prefer html.
I'm using Ubuntu 10.10.
I was able to get this working by simply doing "mkdir parse-cache" in the opencv/doc/latex2sphinx directory.

As I have stated in the title, I'm having trouble installng Frappe/ERPNext on my Docker. I followed instructions from their official Github repo here.
After opening frappe_docker folder in VSCode, when trying to execute the bench init command I got an error. Below are the full code:
frappe#84badc593d50:/workspace/development$ bench init --skip-redis-config-generation --frappe-branch version-14 frappe-bench

I have had user added to docker group as per instruction and have followed it step by step but I got the error above. I've tried run chmod -R frappe:frappe * at the frappe folder but the error still persist.
My machine is running Pop!_OS 20.04 and Docker Desktop 4.16.1
My bad guys, I found the answer.
All I need to do was run chown frappe:frappe /workspace/development/ and all is well. I can run bench init --skip-redis-config-generation --frappe-branch version-14 frappe-bench without a problem after that.
I am trying to buiil Dart-VM on windows, I follow the steps as described here
https://github.com/dart-lang/sdk/wiki/Building
When I run the build.py command as below:
.\tools\build.py --mode release --arch x64 create_sdk
I get the following error:
gn gen --check in out\ReleaseX64

It seems missing the args.gn file in out\ReleaseX64 folder. but I cannot find args.gn in Dart source folders. Is it generated during building process? whether I do wrong steps led to no such file generated?
I am trying to run a tutorial for PyLaTeX in Python 3.5. I am using Anaconda / Spyder. When it runs the command "generate_pdf()", [WinError 2] is generated. Below is the code (it is note quoting properly) and the error. It may be easier simply to look at the link.

Thanks in advance.
I also had the exact same problem, but there was a .log file present in the directory. So I checked out the log, and the last few lines said that a package called lastpage.sty was not found (I'm on Linux), so I just downloaded all the latex packages again using apt.
So I think, you should read the log file too, and if there IS something like that, then go to ctan (all packages are found there) and install the required package for Windows.
Hope it helped.
Also try putting the document.generate_tex() before the document.generate_pdf(filepath="path/to/file", clean_tex=False)

I am getting this error Please let me know how to resolve . . .
This error happens because cmake is either (a) not installed or (b) not on the user's path.
In this case, the OP had downloaded the cmake gui application from cmake.org, and copied it to /Applications. This app doesn't add the path to the binaries automatically, which is why the script couldn't find cmake.
By adding the path to the cmake binaries (bash syntax):
PATH=$PATH:/Applications/CMake.app/Contents/bin
the OP was able to successfully build opencv.
Most package managers - e.g. homebrew or macports whould have automatically added a path to the user's profile that would have permitted it to run without having to modify the path any more.
You may need to install CMake
My-Mac: opencv$ brew install cmake

It seems the python version error,so I update my python to 2.7.3.
then I still got the same error.How could I solve this?
This problem also occured to me and I was almost desperate. I reinstalled Python 2.7.2 and it worked fine.
I tried to solve this problem manually before using the instructions in README_ponyd.rst and I was also partially successful:
Development installation ````````````````````````
If you already have PonyDebugger git repo checked out you can can set
up a virtualenv manually and have your ponyd installation point to
your existing checkout. For demonstration we assume $VENV is set
to your intended install path and $PONYDEBUGGER_PATH is set to
your PonyDebugger git checkout::
# if you don't already have virtualenv installed
sudo easy_install
virtualenv
virtualenv "$VENV"
source "$VENV/bin/activate"
pip install -e "$PONYDEBUGGER_PATH"
# to ensure your shell knows ponyd exists hash -r
To run this ponyd you can either activate your environment by source
"$VENV/bin/activate" and ponyd will be added to your path. You
can also just call it directly via $VENV/bin/ponyd without
activating first.
You should install virtualenv before. You can try combination of both steps. Hope it helps...
