I'm trying to install some packages within Rstudio on my windows computer but I encounter some problems.
When I type in:
install.packages("dplyr")
I get the following error:
Warning in install.packages :

Warning in install.packages :

I've also tried to install packages in the following way:
> install.packages("C:/Users/NLFERM/Downloads/dplyr_1.0.4.tar.gz", repos = NULL, type = "source")
But here I also get an error:
ERROR: dependencies 'ellipsis', 'generics', 'glue', 'lifecycle', 'magrittr', 'R6', 'rlang', 'tibble', 'tidyselect', 'vctrs' are not available for package 'dplyr'
* removing 'C:/Users/NLFERM/Documents/R/R-4.0.4/library/dplyr'
Warning in install.packages :
installation of package ‘C:/Users/NLFERM/Downloads/dplyr_1.0.4.tar.gz’ had non-zero exit status
I already reinstalled R studio and made sure that I have the newest version of R on my computer. Does anyone know how to fix this problem?
Kind regards
Does this work in your R base?
Otherwise are you connected to internet? Or over an enterprise network where cran websites are not accessible?

I'm attempting to set up this Rust template project to get started doing Rust development for ESP32: https://github.com/esp-rs/esp-idf-template
I've installed the Rustup esp toolchain, as described here: https://github.com/esp-rs/rust-build
At the Generate the Project step, I chose these parameters:
Configure project to use Dev Containers = false
ESP-IDF native build version = v4.4
Rust toolchain = esp
STD Support = true
MCU = esp32
At the Build step, I get this output (second run displayed, first run compiles a long list of dependencies before this point):

I get the same error when I choose ESP-IDF native build version = v4.3.2, although without the fatal: No names found, cannot describe anything. messages.
I get an identical error when attempting to build this Rust ESP32 demo project: https://github.com/ivmarkov/rust-esp32-std-demo
This was run as Administrator.
In my search for a solution, I found this: Why os.rename sometimes returns error access is denied python Per the top answer, I disabled "Show frequently used folders in Quick access" in File explorer, but unfortunately the build error has not changed.
What access is being denied, and what could be causing the denial, even when run as Administrator?
Secondarily, what is the cause and meaning of the fatal: No names found, cannot describe anything. messages?
I've been working through the same issue today.
It is caused by a change in the embuild dependency: https://github.com/esp-rs/embuild/commit/d8f8da228f1e1e6c105074d96617a8601092f633
Trying to write permission data to an open file causes the 'os error 5
I've submitted a PR to the project: https://github.com/esp-rs/embuild/pull/56
Now merged, cargo update and you should be good!
I'm currently trying to set up an environment for Yocto project for my personal study.
I was clueless about where to start Yocto so I bought the book Embedded Linux Projects Using Yocto Project Cookbook but it keeps failing to build the environment.
I've run only simple commands. I ran source oe-init-build-env <dir name> to make a directory and ran bitbake core-image-minimal.
But bitbake command keeps giving me errors like this. This is the log.

I feel like I need to modify conf files to fetch available URLs but I'm new to Yocto and Bitbake so I'm very lost now. I would appreciate if anyone could tell me where to find solutions. Thank you and stay safe everyone.
You seem to use quite an old yocto version 1.7.3 while there is already 3.3 released. This means also you try to build recipes for some packages that are also old and hence some URLs might be unavailable. Might it be an option for you to use a newer version?
If this is no option for you, one thing to try would be setting MIRROR (see [1]) to a mirror [2] where those packages are still available. But this approach I would not prefer.
[1] https://www.yoctoproject.org/docs/1.7/bitbake-user-manual/bitbake-user-manual.html#var-MIRRORS
[2] could be: http://downloads.yoctoproject.org/mirror/sources/
1.7.3 is a very old release of the project, originally released in 2015 with a last point release in 2016. The fetcher warnings you see aren't the problem, they're warnings but it will fall back to the project mirrors. If it hadn't fallen back correctly, it would have shown errors as well as the warnings. The bigger problem is in fact this:
WARNING: Host distribution "Ubuntu-18.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.
Since Ubuntu 18.04 is three years newer than the project release you're using, there is no way it would be compatible with that release. You need to use a host OS from the era of the release, so Ubuntu 16.04 may work better. This is because the host OS provides gcc used to build the cross tools and the newer gcc versions don't tend to work with 100% of old code without tweaks.
So in short, use an older distro if you want to try and get that to build.

The only "solution" I could find was to re-install RStudio.

I have installed EmguCV 2.4.2.1777. I have a 32-bit windows 7 so I installed it using the installer. Now I am trying to write a simple code to capture a webcam's video in a window in C#.
The problem is after during execution I am getting the following famous error:
A first chance exception of type 'System.DllNotFoundException' occurred in Emgu.CV.dll
A first chance exception of type 'System.TypeInitializationException' occurred in Emgu.CV.dll
An unhandled exception of type 'System.TypeInitializationException' occurred in Emgu.CV.dll
The file Emgu.CV.dll is present in the folder. I don't understand why its giving that error.
I tried all the checks which are suggested by fellow stackoverflow users and also many other references:
1) Installed MSVCR: MSVCRT 10.0 SP1 x86
2) copied the OpenCV dlls to the execution directory
3) I also have a 32-bit OS. So that also should'nt be an issue.
But when I checked for dependencies, I faced a problem:
I used DependecyWalker to open cvextern.dll and found the following dependencies missing:
NVCUDA.DLL
API-MS-WIN-CORE-COM-L1-1-0.DLL
API-MS-WIN-CORE-WINRT-ERROR-L1-1-0.DLL

API-MS-WIN-CORE-WINRT-STRING-L1-1-0.DLL
API-MS-WIN-SHCORE-SCALING-L1-1-0.DLL
DCOMP.DLL
IESHIMS.DLL
It also gave the following:
Error: At least one required implicit or forwarded dependency was not found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.
Please help me out with the exception. Thanks in advance.
I copied all the dll files from C:\Emgu\emgucv-windows-universal-gpu 2.4.9.1847\bin\x86 to a folder called includes in my project and updated the "Copy To Output Directory" Option for these DLLs to "Copy Always" and it got rid of this issue.
