Solution 1

This is a problem with mingw64 which is messing with the filepaths. The solution is to set the following environment variable before running startFabric.sh :

export MSYS_NO_PATHCONV=1

A fix was just submitted to fabric to do that for you so if you pull the latest version from the master branch it should work. Otherwise, just set that variable and that should solve your problem.

Solution 2

The problem is incorrect path to certificates (look for windows path string between /fabric and /etc) /etc/hyperledger/fabric/C:/ProgramFiles/Git/etc/hyperledger/msp/users/[email protected]/msp

You can try next :

• add path to certificate as environment variable to docker compose file at peer section
• start network using docker-compose -f "path_to_file"
• manually run instructions in startFabric.sh at peer and cli.
• then you can successfully run node query.js for testing network work

Solution 3

The double // in the path will fix this. Update in all the places where docker exec command used for e.g. MSPCONFIGPATH=//etc/hyperledger....

Also certificates have to be generated before you could get your network running

Solution 4

Do this ./byfn.sh -m down first and then run ./byfn.sh generate then ./byfn.sh -m up

The double // is useful . But I don't generated certificates and is work normal。Maybe it has done。

I put it into the shell and It is more useful ,Thanks.

It isn't necessary to run anything from the "Building Your First Network" tutorial before running the fabcar sample.

I have "export MSYS_NO_PATHCONV=1" added in the shell but I am still getting this error. Kindly suggest.
