overview and installation https://github.com/ContentMine/getpapers/blob/master/README.md For example https://github.com/petermr/tigr2ess/blob/master/getpapers/OVERVIEW.md
Installation of getpapersinvolves steps for every operation system.
Instructions followed: https://github.com/ContentMine/getpapers/blob/master/README.md

-
getpapersuses a headless browser (Phantom.js) which still works but is no longer maintained. It is customised forEPMC,IEEE,Crossrefand ?arXiv. It needs a RESTful API. - the query syntax is different on different sites. Also escape characters (
"or') - default query format is EPMC
help in downloading large files with full text content in bulk at a short time duration.
Users can face various problems during the installation process of getpapers. They may encounter errors in their process. Follow the instructions and in case of any installation problem, post an issue about the same in the issue section, or refer to an existing issue if it matches the problem.
If you have Docker installed you may skip the preceding steps and use get_papers using the following Dockerfile
FROM node:slim
WORKDIR /usr/src/app
RUN npm install --global getpapers
This may be built into an image labeled as paper_getter using the following Docker command
docker build -t paper_getter .
A search may then be performed dropping the results into a given folder (here labeled as results) using the following Docker run command (here searching for the term c4 photosynthesis flaveria
docker run -it \
-v $(pwd)/results:/results \
paper_getter \
getpapers -p -x -o /results --query 'c4 photosynthesis flaveria'
This command will mount the folder results into the Docker container as it runs the image paper_getter and the command is written so as to place the results in this folder.
For users facing any usage problems in getpapers they can create an issue regarding the same or may refer the existing ones.
For users using macOS X or higher, a profile needs to be created before downloading nvm. See Tester 8: Charles Li's section.

To search query on a specified task
getpapers -q <query> -n -k <int>
-q, --query : search query(required)
-n, --noexecute : only reports how many queries match the query, but don't actually download anything
For eg: for the query of COVID-19
Use as
getpapers -q COVID-19 -n -k 100
The results will be shown as below:

warn: This version of getpapers wasn't built with this version of the EuPMC api in mind
warn: getpapers EuPMCVersion: 5.3.2 vs. 6.4 reported by api
Output - Founds 68721 open acesss results. This much result cannot be downloaded, so the number of downloads should be limited.
-k, --limit : limits the number of hits and downloads
<int> refers to an integer. Hence, the number of files to be downloaded should be represented.
getpapers -q <query> -k <int> -o <Cproject> -x -p
-o, --outdir : output directory(required - will be created if not found). This is known as the Cproject. This command gives the path to the directory created in the system for the downloaded files.
-p, --pdf : downloads fulltext PDFs if available.

Followed instructions in https://github.com/blahah/installing-node-tools#macos
Successfully installed Xcode but nvm installation showed problems.
Typed in
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh | bash
cURL command was built in so it did not show any errors, but if your mac system did not have cURL built in then you need to add cURL command first, using
sudo apt-get install curl
However it shows error of failed connection to url in previous line (Error 1 in shared folder)
Then I copy and pasted the whole content in https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh to terminal, without the curl command. This ensures the nvm file to be downloaded but it did not find a profile. (Error 2)
So a profile is needed prior to downloading nvm
touch ~/.bash_profile
This creates a profile for nvm and then we can copy & paste content in https://raw.githubusercontent.com/creationix/nvm/v0.30.1/install.sh to run nvm installation again.
After following the instructions on terminal, you can test nvm by
nvm --version
which should say the current version of nvm installed on your computer (Final in shared folder)
You can test if Node.js is installed after the lines by
node -v
If you have other problems installing nvm on macOS, see this discussion page

Eg. Run the following syntax on the command prompt
getpapers -q viral epidemics -nIt is found that 312120 open access results were available for our search. Since we cannot download all of them, we will have to limit the downloads.

I went ahead and deleted the .npmrc file associated with configured proxy.
