NodeJS 12.x: Not found Error in AWS Greengrass

I couldn't know where to tag my question properly, if I made a mistake I am so sorry. (I am new in stackoverflow).

I am trying to build an AWS Greengrass environment and I have a problem with installing the necessary packages.

I just installed NodeJS to my Ubuntu 20.04.1 in Virtual Machine:

VirtualBox@VirtualBox:~$ sudo apt install nodejs
Reading package lists... Done
Building dependency tree       
Reading state information... Done
nodejs is already the newest version (12.19.0-deb-1nodesource1).
0 upgraded, 0 newly installed, 0 to remove and 243 not upgraded.

VirtualBox@VirtualBox:~$ node --version
v12.19.0

So, I have NodeJS. Then I followed these commands:

cd /greengrass/greengrass-dependency-checker-GGCv1.10.x
wget https://github.com/aws-samples/aws-greengrass-samples/raw/master/greengrass-dependency-checker-GGCv1.10.x.zip
unzip greengrass-dependency-checker-GGCv1.10.x.zip
cd greengrass-dependency-checker-GGCv1.10.x
sudo check_ggc_dependencies | more

And now it displays this:

----------------------------Commands and software packages--------------------------
Python 2.7 version: 2.7.18
Python 3.7 version: 3.7.9
NodeJS 12.x: Not found
Java 8: Not found

I don't get it, I have NodeJS but why it says Not found

Do you have any opinion or suggestion to me?

I would be so happy if you can answer this, it took 3 hours for me to search but still couldn't solve..

Solution

  • I solved it and I would like to share my solution for it;

    I followed the steps here: https://github.com/aws/aws-greengrass-core-sdk-js

    To download the NodeJS:

    curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -
sudo apt-get install -y nodejs

    After that you find node file under the bin directory.

    Copied the file and pasted it to the desktop. The reason is that, we are not able to paste files under the /usr/bin directory, only root is allowed for this.

    In the desktop, I changed the name of the file to nodejs12.x

    And then opened a terminal in Desktop and run this command:

    sudo cp nodejs12.x /usr/bin

    The cp command is for giving the root acces. Source: https://askubuntu.com/questions/921797/unable-to-paste-a-file-to-usr-folder

    Now, the node file under the bin directory is copied under the /usr/bin directory and named as nodejs12.x. In the end, my problem is solved:

    Python 2.7 version: 2.7.18
Python 3.7 version: 3.7.9
NodeJS version: 12.19.1
