i already installed the both cheese and gucv application for simple output from usb, but then i had trouble with installing the usbcam packages for ROS.
How can i install the usbcamera packages?
i tried to install the ros-fuerte-camera-umd, but it says that unable to locate that package.
Please refer to Create a ROS workspace
Then download the package and save it in your_working_space\src\
Later go back to your_working_space and run catkin make it will install the package.

I was trying to install Ursina but I was having trouble getting all the required packages I needed to run my code properly. Come to find out, there's a package that refuses to install called 'psd-tools3' that won't install, no matter what I do.
I've been using cmd commands like 'pip install psd-tools3' and 'pip3 install psd-tools3' but no other commands work (i.e. 'sudo pip install psd-tools3' doesn't work because my PC doesn't know what 'sudo' means and doesn't run). I've tried installing required packages for this package, but nothing works. It just keeps giving me this error:

I would really appreciate the help with this problem. All I can really assume is that the Python file '_version' hasn't been created and that's what's throwing the whole program off. If there is a way to add this manually and then install it, I would appreciate steps to do that as well.
I was running this on a Lenovo Thinkpad (Windows 10) on Python 3.10 (I also have Python 3.8.3 but that was installed with the 3.10) and I made sure all packages and pip are up-to-date. Still having this problem and I don't know why.
Seems to me like the issue is on the side of the maintainers of psd-tools3.
For example, looking at the content of the latest source distribution on PyPI, we can see that it does not contain any _version.py file.
This needs to be solved by the project's maintainers, but they do not have a ticket tracker. On the other hand there seems to be an "Author" email address on the project's PyPI page as well as in the project's setup.py script.
A solution might be to clone the project's source code repository (with git), and try to install from the local clone.
Just simply try
pip install psd-tools3==1.9.0
Or
pip install psd-tools3==1.8.2
This should work on your pc as well. I was having same issue, and then I tried this It worked for me
I want to use the package "Dask", but there is one problem.
"Dask dataframe requirements are not installed."
Obviously, we can use pip install "dask[dataframe]" or pip install "dask[complete]".
However, in the secured server where I work, there is no internet connection.
So, I transfer the file of package and install manually.
But, I cannot find the package dask[dataframe] for downloading.
How can I install the rest of packages manually without internet connection?
Thank you
You should look at the setup.py requirements file in the dask repository to see which dependencies it requires.
I created virtual environment for python 3.4 version.I cant able to use pip from my network. I cant able to download files even. So i created virtual environment and started to install packages using conda install.
When i was using this command conda install -c syllabs_admin justext, i'm getting notification from my server like:
The following packages will be SUPERSEDED by a higher-priority channel:
python pkgs/free::python-3.4.5-0 --> pkgs/main::python-2.7.17-h9bab390_0
Can someone actually help me how to install this justext package for my python version 3.4 using conda install?
Unfortunately, no. There is no way that you can use conda install with any public channel to install justext and your python version. Checking the search function on anaconda.org, there are only two channels that provide justext:
moustik / justext 2.2.0
syllabs_admin / justext 2.2.0
Unfortunately, both have only python 2.7 packaged versions of the module.
you should try to fix your networking issues instead. It sounds really werid that conda install would be working while you claim to not be able to even download any files. Please talk to your IT department or Sys Admin about it or ask another question posting the errors you are getting when using pip install or wget https://files.pythonhosted.org/packages/6c/5f/c7b909b4b864ebcacfac23ce2f6f01a50c53628787cc14b3c06f79464cab/jusText-2.2.0-py2.py3-none-any.whl
I successfully installed pear & pecl on my windows machine.
Now, i would like to install gnupg extension using pecl.
My need is to get the gnupg.so extension for php7 to upload it on a linux server on which I have no rights. The extension does not exist on this server, this is the reason why I need to get it to transfer it.
When I run pecl install gnupon my machine, I get the following result:
C:\WEB>pecl install gnupg-1.4.0.tgz
6 source files, building
ERROR: The DSP gnupg.dsp does not exist.
After some research, I found out that I migth need a .dll but there is no way to find anything about it.
Is there anyone who can help me?
pecl install downloads the source code and compiles it for the system pecl runs on. It will not work on a different system, especially not on a Linux one when you are compiling it on windows.
You have three options that will work, in order of preference:
Install the distribution-provided pecl-gnupg package
Run the pecl install command on your server
Setup an identical machine as your live server, run pecl install on it and copy the generated .so file to your live server.
I am trying to install psycopg2 under Windows (Windows 7, 64 bit). I am using Python 2.7.2 from Python(x,y) and PostgreSQL 9.2.1 .
My first try was using the windows port that is downloadable from http://www.stickpeople.com/projects/python/win-psycopg/ (psycopg2-2.4.5.win-amd64-py2.7-pg9.1.3-release.exe). I get a message then that
Python 2.7 required but was not found in the registry
In the next dialogue it does not allow me to choose any python installations. All other programs and installations find my python happily.
This being failed, I tried to use the source package directly from http://pypi.python.org/pypi/psycopg2 but after trying:
python setup.py install
I am now stuck with the error message:
error: Unable to find vcvarsall.bat
Does anybody have an idea how to solve this?
You're using a different Python distribution to the one the psycopg2 installer expects, so it cannot find the Python install location.
You can manually install psycopg2 from the binaries you downloaded by following the instructions on the psycopg2 download page for issues installing with Zope, which read:
It has been noted that the the installers for psycopg2 will not find
the zope installation of python, stop the installation, and not
installing psycopg2. A work around is to extract the files by renaming
the extension from *.exe to *.zip and using a zip extractor (such as
WinZip/PkZip/7z) to extract the psycopg2 folder and place it at
\lib\python. I do not use Zope, so I will not be able to
provide support or instructions on how to use it. Let me know if it
does not work, though.
The same will apply to the Python(x,y) distribution that you are using. Unzip the psycopg2 installer .exe using 7-zip, then copy the psycopg2 folder and 'psycopg2-2.5.2-py2.7.egg-info' file (so 'psycopg2' will apear on 'pip freeze') into your Python lib\site-packages directory. See installing Python modules.
You should then be able to import psycopg2.
