This express command is not running.
E:\node>express test
'express' is not recognized as an internal or external command,
operable program or batch file.
Installing express globally helped me out.
npm install -g express

Sorry for the German question before.
I have the following problem. I search about it in the internet but i did't was successfull.
I wanna run my node script with my npm-dev script.
I execute " npm run dev". Normal like everytime.
Than i got this error message:
It means that node cannot be found.
I can execute via the Terminal my JS-File with "node index". Just all my npm-scrips doesn't work.
I think that i have some problems with the environment variables. But if I execute " node -v" or "npm -v" everything work fine.
In my PATH i have " C:\Program Files\nodejs" Not sure if that is all what I need?
Thanks in advance if someone can help me with this Problem.

bash: npm: command not found.
Copy the address of file where your nodejs is stored and then go to Enviroment variables advance setting select "path" from upper window list,
then click edit
and then add a ";" in given path then paste the copied address of the nodejs file
Now you can run npm from anywhere !
Uninstall and Reinstall fixed it

I am trying to run Python in my command prompt, but when I tried it tells me python is not recognised as an internal or external command, operable program or batch file
First of all, if you didn't installed python yet, install it! https://www.ics.uci.edu/~pattis/common/handouts/pythoneclipsejava/python.html
to run a program from inside the terminal (both in Windows and Linux) it need to be in the environment PATH variable - this way the terminal knows where the actual exe/elf is.
For example, if you installed the python in C:\Python37\python.exe, the PATH should contain that path.
Please read this article which explains how to add Python to the Windows PATH - https://geek-university.com/python/add-python-to-the-windows-path/

I need to covert Perl data into PDF. For that I have installed CPAN into my UNIX system, Now I need to install PDF::API2. So please give the UNIX command to install PDF::API2.
I think you need this command,
sudo apt-get install libpdf-api2-perl
or,
sudo perl -MCPAN -e "install PDF::API2"

https://raw.github.com/AmazonEMR/bootstrap.actions/master/node/install-node-bin-x86.sh
That simply just. doesn't. work.
downloads that file. Add:
node --version
At end of it.
"On the master instance (i-d6c6a28b), bootstrap action 1 returned a non-zero return code"
The script works.
Adding the
node --version
Doesn't work because the path to node executable was appended as environment variable for your bash. This does not take effect until next time you sign in.
What was chocking for me was that the example from AWS was bad.
https://github.com/AmazonEMR/sample.apps/blob/master/node/sample-mapper.js
Some how
process.stderr.write(err);
doesn't work.
Edit- Try running that install-node-bin-x86.sh line by line through ssh. It will all run fine. Node --version still doesn't work. BUT. log out the SSH session and connect again. Then do 'Node --version' it will work.
