Backports 1.1.1 Package Fails to Install

backports 1.1.1 package fails to install

I'm getting a similar error with the backports R package. It's preventing the devtools package from installing a customised package which I've written.

I fixed it by installing the previous version of backports:

require(devtools)
install_version("backports", version = "1.1.0")

Unable to knit R program (there is no package called 'backports'

I also got this issue. It seems there is some problem with the CRAN source for this package. I installed the binary version from https://cran.r-project.org/web/packages/backports/index.html and it worked.

Could not install packages due to an EnvironmentError: [Errno 13]

If you want to use python3+ to install the packages you need to use pip3 install package_name

And to solve the errno 13 you have to add --user at the end

pip3 install package_name --user

EDIT:

For any project in python it's highly recommended to work on a Virtual enviroment, is a tool that helps to keep dependencies required by different projects separate by creating isolated python virtual environments for them.

In order to create one with python3+ you have to use the following command:

virtualenv enviroment_name -p python3

And then you work on it just by activating it:

source enviroment_name/bin/activate

Once the virtual environment is activated, the name of your virtual environment will appear on left side of terminal. This will let you know that the virtual environment is currently active.
Now you can install dependencies related to the project in this virtual environment by just using pip.

pip install package_name

UnsatisfiableError on importing environment pywin32==300 (Requested package - Available versions)

Build tags in you environment.yml are quite strict requirements to satisfy and most often not needed. In your case, changing the yml file to
