Chainlink101 Course - Node Setup

[Su.kal.Crypto]

Hi All Fellow awesome Coders (Especially salute to all Advanced Super shadowy devs )

I have been trying to follow the Chainlink101 Course by Pattrick Collins as I am very excited by Oracle Networks and their capabilities

However, I am stuck in the Section Chainlink Local (in Heading “Chainlink Advanced”). I have download all the necessary softwares as per instructions of Pattrick including ‘Go’, ‘Postgres’, ‘psql’, ‘homebrew’, ‘yarn’, and plus I am also using 12.18 version of node.
Inspite of all this, when i go to directory chainlink and enter command ‘chainlink help’ or just ‘chainlink’, the terminal prompts ‘chainlink not found’
I have also tried chainlink run node, again the same Error “chainlink not found”

I have already cloned the chainlink repository from github and also run ‘yarn install’ inside this directory and also added dependencies using ‘make install’. Basically I have followed all instructions carefully.

But it still doesn’t work ??

Also, Tried to read docs.chain.link and tried setting up the Ethereum Client first and then tried again, still not working…My Postgres database is working fine. Also, i tried to install Docker ( but couldn’t really understand how to use for client - can someone explain this too ?)
Can someone please help ? Also, there is no forum I see for Chainlink course where I can ask these technical questions, hence I am forced to create a New Topic here.

Please see attached the Terminal screenshots

Thanks and Regards

Hey @Su.kal.Crypto, hope you are ok.

Glad to know you are enjoying the chainlink course.

Now about the local chainlink node, the video does not explain in detail the entire process, is just a quick review of it, the installation process is quite complex and requires to have many knowledge on computers that are now explained in this course.

For example, is not only about installing postgres, psql, yarn, etc… You have to manually config each of those tools to work properly like the installation guide said, but it does not explain the process for each (like configuring SSL for postgres).

NOTE: Keep in mind that the video is a quick review, not mean to describe the entire process. Also, the local chainlink node is not needed to move forward with the course, for the programming category (which will be the lottery project), you will use one of the chainlink testnet nodes.

Hey thanks Carlos,
I will continue with my Chainlink 101 Course and pester you in case i get stuck again.

Meanwhile, This academy is great. I have completed DAPP + Smart Contract Security + ETH 201 Courses too. Also, I have literally gone through each line of code of UniV2 and now currently studying aave-v2 protocol rep on github too.
I feel I am ready now, my concepts are all Clear, except for the permit functions - i dont still get it how in the real life applications will they work, maybe i will get an idea when i go through aave contfacts fully?

Carlos, is there a way i can progress further ? I mean i can work for free, i just need a real project and a Team or let’s say a mentor like @abcoathup on Twitter who keeps posting Educational content on openZeppelin forum.
Can you mentor me, do you have the time? Maybe a project i can work on ??

Thanks and Regards
