here is screenshot :-

please let me...
thanks in advance
You should ideally request support from the IBM Cloud Portal (link here -> https://console.bluemix.net/docs/services/blockchain/ibmblockchain_support.html#ibmblockchain_support) - you can also see ANSWERS here on the IBM site -> https://developer.ibm.com/answers/smart-spaces/261/blockchain.html
If using its Enterprise plan my guess is that you should be using this guide for 0.16.x of Composer -> https://hyperledger.github.io/composer/v0.16/tutorials/deploy-to-fabric-single-org (to match your Composer version) - the tutorial link you provided is for version 0.19.x of Composer which has a different command sequence and probably explains the 'syntax' issue. Hope this helps.
If you are only installing hyperledger now, be aware that some of the commands have been removed in hyperedger 19.0 which is the latest version as of today, refer to this link for more information on removed and new commands.

some files are missing from the Fabric samples, docker images, and binaries download like the first-network folder and others. how do I get the missing files imported on vscode?
At the time of writing, first-network no longer exists as a Hyperledger Fabric sample. If you are using an old versions of Fabric (for example, v1.4) and the corresponding documentation, which does describe first-network, you will need to make sure you specify the appropriate version when installing Fabric components so it pulls the samples from the correct branch of the samples repository. For Fabric v1.4, that would be this branch:
https://github.com/hyperledger/fabric-samples/tree/release-1.4
If you are using the latest version of the Fabric and its documentation, test-network is now used to deploy a sample network and chaincode.
I has been deployed (this awesome deprecated tool named) hyperledger composer. After a couple of days working, click on a network card emit an error and I'm unable to login. After give up, reinstall everything from zero, does not remove this cards. Already deleted ~/compose* files, also teardown fabric and docker containers.
So my problem have two solutions:
One, find where are composer model and scripts stored to recover.
Two, fix and/or remove these files.**
Question: Where are CTO and js script files stored?
I will suggest you not to you use Composer as it is has been deprecated. Please read here. https://github.com/hyperledger/composer/blob/master/README.md
I am using composer v.0.20.8 currently
and I keep updating my .bna file.
but every time I generate a new .bna file I have to teardown my fabric network and redeploy it.
Is there a way where I can just deploy it without tearing down my network in v.0.20.8 Composer?
Composer provides a upgrade utility to do just that. Please see the below link for reference.
Upgrading a business network
Let us know if you get stuck in the process.
Using HLF 1.4 and trying to conform to documentation, however, docs indicate that go 1.11.x MUST be installed -- is there not support for go 1.12.7? If not, when? 1.11.x is considered "archived".
Please advise. Thanks.
I'm currently running fabric 1.4.3 with go version 1.13.5 so it seems that the docs are out of date
Hey could someone help me with this doubt?
I am a very beginner and not the typical profile of a developer. For a project I need to define the environment around blockchain. I need to define every tool you need and everything to install to develop and deploy software using Hyperledger Fabric.
As far as I know I will need to install the prereqs:
Docker Engine
Docker Compose
Node
npm
git
Python
VS Code
All of them are considered developing tools, isn't it?
Other tools I need will be:
Clients (CLI tools)
Apache server?
Playground. (What is that?)
IDE
Hyperledger Fabric (Is it similar to the EVM?)
Loopback and Swagger??
APIs
Anything else to add? Really thankful for helping me
you wil not need a server initially during developement (can be done locally). An IDE (VSCode is one of them !) will not be needed if you are already getting VSCode. If youre a beginner - Hyperledger Composer (runs over a hyperledger fabric instance) would probably be better to start with. Playground as you mentioned is a user interface of sorts that helps in defining,deploying and testing blockchain networks (can be visited online at https://composer-playground.mybluemix.net/). To develop networks locally you could download them and develop locally. There are many links available and if you need more I would be happy to link them ! (This series is also very helpful (IBMs ZeroToBlockchain playlist - https://www.youtube.com/watch?v=CgGX-BTYOwA&list=PLnJzIOiv6cVTjaJRtJ2srarhs-m4V3zs3)
Hyperledger Explorer is also a very useful tool for viewing your network and the data stored in the ledger.
You ought to check out Chaincoder IDE. It is a project I am working on. Helping people to get started with Hyperledger Fabric and uses almost standard CLI commands and configuration files of Fabric to get a blockchain system running either locally with docker or remote with different hosts. It is free and easy to use.
