Reproducing the error
1. git clone https://github.com/zkopru-network/zkopru
2. cd zkopru && yarn && yarn build
Temporal Solution, yarn build again, no more error message.

Could not find some module when start cli app if not ran yarn build:fresh ever.

Reproducing the error
1. git clone https://github.com/zkopru-network/zkopru
2. cd zkopru && yarn && yarn build
3. yarn build again
4. run ganache testnet which is deployed zkopru contracts as container docker-compose -f compose/docker-compose.dev.yml up testnet
5. modify values in packages/coordinator.dev.json or replace by this coordinator.dev.json
  - "ws://testnet:5000" --> "ws://127.0.0.1:5000" at websocket
  - "/proj/coordinator-wallet.db" --> "coordinator-wallet.db" at sqlite
6. run zkopru cli app node packages/cli/dist/apps/coordinator/cli.js --config packages/cli/coordinator.dev.json
Temporal Solution Do use yarn build:fresh instead yarn clean && yarn build
