Adding the correct Path variables to .profile for Node.js

The PASE implementation on IBM i is not the easiest to work with! I just posted about the setting of the environment to allow the Node.js package manager and Node.js to run from any directory (On first installation you have to be in the ../Node/bin directory for anything to work) and mentioned that I was not going to add the set up to my .profile file in my home directory. First of all make sure you have the home directory configured correctly, I found from bitter experience that creating a profile does not create a home directory for it…

Once you have the home directory created you are going to need to have a .profile file which can be used to set up the shell environment. If you use the IFS commands to create your .profile file ie ‘edtf /home/CHRISH/.profile’ be aware that it will create the file in your jobs CCSID! So once you create it and BEFORE you add any content go in and set the *CCSID attribute to 819, otherwise it does not get translated in the terminal session. When you are working with the IFS the .xx files are normally hidden so make sure you go in and set the view attributes to *ALL (prompt the display option ‘5’) or use option 2 on the directory to see all the files in the directory. I personally dislike the IFS for a lot of reasons so my experiences are not always approached with a positive mind set.

Once you have the file created you can add the content to the file.

PATH=$PATH:/QOpenSys/QIBM/ProdData/Node/bin
export PATH
LD_LIBRARY_PATH=/QOpenSys/QIBM/ProdData/Node/bin
export LD_LIBRARY_PATH

Again care has to be taken, if you use the edtf option you will not be able to get around the fact that IBM’s edft always adds a ^M to the end of the file which really messes up the export function! I am sure there is a way to fix that but I have no idea what it is? So if you know it let everyone know so they can work around it!

Here is an alternative approach and one which works without any problems. Sign onto you IBM i using a terminal emulator (I used putty) and make sure your in you home directory, in my case ‘/home/CHRISH’. Then issue the following commands.

> .profile
echo 'PATH=$PATH:/QOpenSys/QIBM/ProdData/Node/bin' >> .profile
echo 'export PATH' >> .profile
echo 'LD_LIBRARY_PATH=/QOpenSys/QIBM/ProdData/Node/bin' >> .profile
echo 'export LD_LIBRARY_PATH' >> .profile
cat .profile

You should see output similar to the following.

PATH=$PATH:/QOpenSys/QIBM/ProdData/Node/bin
export PATH
LD_LIBRARY_PATH=/QOpenSys/QIBM/ProdData/Node/bin
export LD_LIBRARY_PATH

When you check the IFS you will see that .profile has been created with CCSID 819. The content is correctly formatted.

Now simply end the terminal session and start it again, sign on and you should be able to run the npm -v command and see the version correctly output. If you see junk or error messages being sent when your terminal sessions starts you have done something wrong.

Now onto building a test node.js app with IBM i content 🙂
