~/eos/build/programs/eosio-launcher error to create multi-node in local testnet

Expected behavior

The following is my trial on private testnet to run multi nodes, not public testnet. I want to try it later.

BTW, to setup a node, it was warned that I need at least 8G memory.

sudo git clone https://github.com/eosio/eos --recursive

cd eos
./eosio_build.sh

For ease of contract development, one further step is required, be aware, you need to go to build fold

cd build
sudo make install

Then I tried to run multi nodes in my local testnet:

cd ~/eos/build
cp ../genesis.json ./
./programs/eosio-launcher/eosio-launcher -p2 --skip-signature

It is expected to create two nodes locally:

spawning child, programs/eosiod/eosiod --skip-transaction-signatures --data-dir tn_data_0
spawning child, programs/eosiod/eosiod --skip-transaction-signatures --data-dir tn_data_1

Actual behavior

However, I came across this error while running:
/programs/eosio-launcher/eosio-launcher -p2 --skip-signature

is not a valid path.

How to reproduce

With my process above, it is easy to reproduce this issue.

The tutorial I was following:

https://github.com/EOSIO/eos
