Hyperledger Composer Incompatible versions error a

Question

Executing:

composer network ping -n calma-network -p hlfv1 -i admin -s adminpw

I receive the following error:

Error: Error trying to ping. Error: Composer runtime (0.8.0) is not compatible with client (0.11.0)
Command failed

The versions look the same:

composer -v

composer-cli                   v0.11.0
composer-admin                 v0.11.0
composer-client                v0.11.0
composer-common                v0.11.0
composer-runtime-hlf           v0.11.0
composer-runtime-hlfv1         v0.11.0

Answer 1

I encountered the same problem. The fix for me was to first find the location of composer by typing which composer in the terminal. Then I manually deleted the directory containing it rm -rf /PATH/OF/COMPOSER. Then run npm install -g composer-cli@latest. After type composer -v to verify new version.

Answer 2

I also faced the same problem and found an issue ..

Problem

while executing below command got an error composer-rest-server -c admin@airlinev8 -p 3000

Nitishs-MacBook-Pro:fabric-dev-servers nitishbhushan$ composer-rest-server -c admin@airlinev8 -p 3000 Discovering types from business network definition ... Connection fails: Error: Error trying to ping. Error: Composer runtime (0.19.9) is not compatible with client (0.19.8) It will be retried for the next request. Exception: Error: Error trying to ping. Error: Composer runtime (0.19.9) is not compatible with client (0.19.8) Error: Error trying to ping. Error: Composer runtime (0.19.9) is not compatible with client (0.19.8)

solution

step 1: check version of composer-cli and composer-rest-server composer-cli - 0.19.9 composer-rest-server - 0.19.8

step2: install latest version of composer-rest-server npm install composer-rest-server -g

After this step, I ran the command again and it worked :-)

Answer 3

You need to install the same version everywhere.In your case if it is 0.8.0 then make everything same with the command as below.

npm install -g composer-cli@0.8.0 --save
npm install -g composer-admin@0.8.0 --save
npm install -g composer-common@0.8.0 --save

...like wise.

You can also try with the following.

sudo npm install -g composer-rest-server@0.8.0

cheers!

Answer 4

Rebooting Hyperledger Fabric (stopFabric.sh, teardownFabric.sh and startFabric.sh) solves the error.

Answer 5

I got a similar error but differently:

Error: Error trying to ping. Error: Composer runtime (0.11.1) is not compatible with client (0.10.1)

OP had old runtime and new client, but in my case, I had new runtime and old client. I was not able to solve the problem by Rebooting Hyperledger fabric. Instead, I updated composer-rest-server and it worked.

sudo npm install -g composer-rest-server

Note: After rebooting hyperledger fabric, you need to re-deploy the chaincode or say bna file in my case.

Answer 6

Ran into a similar issue

trying to ping. Error: Composer runtime (0.16.5) is not compatible with client (0.16.3)

This was because composure had newer version than composure-playground. To fix this

• Shutdown the composer
• npm install -g composer-playground
