I'm using following command to build a package to distrubte
yarn run electron-pack
It creates a dist folder.
If i want to create a patch for distribution , which command should I use ? I want to make sure certain files related to DB are not changed after patch or update
Im not able to find a good command

I am trying to fix a bug in a python package for my project that runs inside a docker container.
The package I am talking about is django-allauth and I found a small with one of the providers.
I know that I need to copy the edited package into the container and install it like this:
COPY folder/with/package /somefolder_inside_container/
RUN pip install -e /somefolder_inside_container/
The root folder of this project on github contains a lot of files and I am not sure if I should include them for copying to make sure the package installs. Do i need to copy anything besides the 'allauth' folder that contains all the models/views/etc. ?
I have a kinda weird problem. I'm currently messing around with the VRX-Simulator, which simulates an unmanned-watersurface-vehicle.
For the installation I followed the guide on https://bitbucket.org/osrf/vrx/wiki/tutorials/SystemSetupInstall.
Then I tried to modify some of the files and tried to rebuild the project.
This was the point when I noticed it always used the "old" version of my simulation within gazebo.
From now on no matter what I did (I even deleted the whole catkin workspace folder) ROS somehow managed to always launch the original version of my simulation even without any build/src folder existing when I used roslaunch.
roslaunch vrx_gazebo sandisland.launch
So my question would be how can I get rid of my simulation/model and where does ros/gazebo cache my simulation?
You most probably installed the package with the command from the tutorial sudo apt install ros-melodic-vrx-gazebo. So the package launched with roslaunch vrx_gazebo sandisland.launch was not in your catkin workspace. If you want to get rid of it you can uninstall it with sudo apt remove ros-melodic-vrx-gazebo. But this is not strictly necessary.
There are several ways to find out where some ros package is located, try running some of these commands:
rospack find vrx_gazebo will show you where the package used is located
roscd vrx_gazebo will take you to the folder where it is installed something like
/opt/ros/melodic/share/vrx_gazebo
If you also followed the tutorials installing from source code then the issue most likely was not sourcing the built packages. The last line of the guide is a bit misleading. The line *Remember to run this command every time you open a new terminal. is meant to reference the command source ~/vrx_ws/devel/setup.bash
Whether the installed package or the package built from source is used depends on which order they are listed in the environment variable ROS_PACKAGE_PATH. This variable is modified by both source /opt/ros/melodic/setup.bash and source ~/vrx_ws/devel/setup.bash. So have a look at the variable after each step with printenv | grep ROS or echo $ROS_PACKAGE_PATH. Theoretically if you source your terminal in the order I had the source commands it should be using the package built from source, you can verify with the rospack find ... and roscd ... commands mentioned earlier.
In the end it is probably easier to add the sourcing commands to your .bashrc file so you would not forget to source the terminals as mentioned in the ROS installation tutorial. You can add the sourcing of the workspace to the the same file, you will just have to be aware that you would need to change the file, should you want to use a different workspace.
http://wiki.ros.org/melodic/Installation/Ubuntu#melodic.2BAC8-Installation.2BAC8-DebEnvironment.Environment_setup
relevant command from the tutorial:
echo "source /opt/ros/melodic/setup.bash" >> ~/.bashrc
you could do the same for the workspace:
echo "source ~/vrx_ws/devel/setup.bash" >> ~/.bashrc
And after running those commands run exec bash to get the changes into the current terminal. All future terminals will have those commands already loaded.
I have cloned and built the waf script using:
./waf-light configure
Then to build my project (provided by Gomspace) I need to add waf and the eclipse.py to my path. So far I haven't found better than this setenv script:
WAFROOT=~/git/waf/
export PYTHONPATH=$WAFROOT/waflib/extras/:$PYTHONPATH
export PATH=~/git/waf/:$PATH
Called with:
source setenv
This is somehow a pretty ugly solution. Is there a more elegant way to install waf?
You don't install waf. The command you found correctly builds waf: /waf-light configure build Then for each project you create, you put the built waf script into that projects root directory. I can't find a reference, but this is the way in which waf:s primary author Thomas Nagy wants the tool to be used. Projects that repackage waf to make the tool installable aren't "officially sanctioned."
There are advantages and disadvantages with non-installation:
Disadvantages:
You have to add the semi-binary 100kb large waf file to your repository.
Because the file contains binary code, people can have legal objections to distributing it.
Advantages:
It doesn't matter if new versions of waf break the old API.
Users don't need to install waf before compiling the project -- having Python on the system is enough.
Fedora (at least Fedora 22) has a yum package for waf, so you could see that it's possible to do a system install of waf, albeit with a hack.
After you run something like python3 ./waf-light configure build, you'll get a file called waf that's actually a Python script with some binary data at the end. If you put it into /usr/bin and run it as non-root, you'll get an error because it fails to create a directory in /usr/bin. If you run it as root, you'll get the new directory and /usr/bin/waf runs normally.
Here's the trick that I learned from examining the find_lib() function in the waf Python script.
Copy the waf to /usr/bin/waf
As root, run /usr/bin/waf. Notice that it creates a directory. You'll see something like /usr/bin/.waf-2.0.19-b2f63c807a4215294bf6005410c74c18
mv that directory to /usr/lib, dropping the . in the directory name, e.g. mv /usr/bin/.waf-2.0.19-b2f63c807a4215294bf6005410c74c18 /usr/lib/waf-2.0.19-b2f63c807a4215294bf6005410c74c18
If you want to use waf with Python3, repeat Steps 2-3 running the Python script /usr/bin/waf under Python3. Under Python3, the directory names will start with .waf3-/waf3- instead instead of .waf-/waf-.
(Optional) Remove the binary data at the end of /usr/bin/waf.
Now, non-root should be able to just use /usr/bin/waf.
That said, here's something to consider, like what another answer said: I believe waf's author intended waf to be embedded in projects so that each project can use its own version of waf without fear that a project will fail to build when there are newer versions of waf. Thus, the one-global-version use case seems to be not officially supported.
I have just installed Yeoman, and generator-aspnet
Project is created, I go to the controllers folder to add a new controller, and I get an error .
I run
yo aspnet:MvcController Test
You don't seem to have a generator with the name “aspnet:MvcController” installed.
I do npm install aspnet:MvcController but it cant find it. What am I doing wrong?
I am having a issue creating a yeoman project. I cd in the directory type yo and it says:
Here is it suppose to asked me project name etc and it wants to throw everything on my desktop not the file I cd into. It defaults to mvn and I want gradle. I even npm uninstall -g generator-jhipster
and reinstalled it and got the same issue.
If you have a .yo-rc.json file in a parent directory, Yeoman will load that configuration and generate from that file instead of prompting. This allows developers to run a yo command from any folder in the project and have it apply to the correct files.
To solve this, remove the .yo-rc.json from the parent directory, in your case /Users/drew/Desktop.
For example, if you are in the directory /Users/drew/Desktop/new-project but /Users/drew/Desktop has a .yo-rc.json inside, Yeoman will change to the parent directory (Desktop), load the configuration, and generate the files from that folder instead of the child folder.
Based on your log it's looks like you are running yo in a folder where a .yo-rc.json is already existing. Careful under windows the .yo-rc.json can be that is of type hidden and you can't see it in explorer. Because of an existing .yo-rc.json you are not asked anymore for info e.g. project name, build tool etc. My recommendation will be to create a new folder run inside yo command
