The graph application development Mac10 / certos 8 environment configuration


This paper introduces the construction of the environment based on the scene of the team developing the graph application Subgraph: the offline development machines are complex. Take the MAC machine as an example to explain the configuration step by step. The online environment is relatively clean, but there is a lack of auxiliary software. It needs to be deployed from scratch. Readers can read it as needed.

For example: Ganache cli – H – V / DB – B 6 – a 8 – e 1000 – d expect chair to trade spider wedding say item scale fog shrimp Gallic
Open the presence library, set the automatic mining time 6, set 8 1000gas accounts, and import the existing private key (- D, can be external or – M)

Pull graph node (complex environment process at this level)

download…, put the installation into the app, run and enter the password, and the command line is available.

Everything looks very normal, but various problems may occur in subsequent installation. It varies depending on your local software and hardware environment, but you need to be calm about it.

$ brew install jq
$ docker -v

Brew install installation and update started badly. For pit filling, see brew upgrade installation and error reporting to solve the remaining problems of brew upgrade MAC update components.
Docker version 20.10.5, build 55c4c88 OK.
Pull graph node

$ git clone

The common resource pits in areas inaccessible to human resources, such as git, can be seen in the agent and mirror pits. Sometimes it’s time to try again and again. In the past, cherish the labor achievements and back up some resources. In case of force majeure in the future, you can copy / paste these files (or directly use your colleagues’ clean environment to obtain local files and solve your environmental problems later)

Configure to start the graph

$ cd graph-node/docker
$ ./ #write the host IP address into docker-compose.yml.
$ docker-compose up #Start a local Graph Node that will connect to Ganache on your host

$ graph init --from-example moluoping/mark-cion 
 #graph init --from-example <GITHUB_USERNAME>/<SUBGRAPH_NAME> [<DIRECTORY>]

The generated yarn function lock file locks the version of the dependent package and the source URL. It cannot be mirrored
Solution: back up lock, use NPM to pull down all packages (Taobao image is incomplete, use official
(compare version dependency) see proxy and mirror pits for resource pits

The above is through the example production contract and subgraph

You can also generate a subgraph project directly from the contract wizard in the container:

$ graph init --from-contract 0x1e1215caD01aD7192832e0DACfA930Caf0132b43  --network mainnet --abi markdemo4.json moluoping/markdemo4

Listen to the contract. Configure through the contract ID

$ sed -i -e 's/0x2E645469f354BB4F5c8a05B3b30A929361cf77eC/0x71e11bC372507d508E05f65c096d32F1eF62Cdf7/g'     subgraph.yaml

If you make a low-level mistake here, the second contract is really effective, but the second instruction is to achieve the effect
sed -i -e ‘s/0x2E645469f354BB4F5c8a05B3b30A929361cf77eC/0x0A994866b43562c083C81E1B4AD6145214f56c56/g’ subgraph.yaml

Proxy and mirror pits

Pay special attention to the conflict between port 8001 and Vray HTTP proxy port

Pay special attention to agent, agent, agent

When we are not in the proxy, we are on the way to the image. Sometimes GIT and yarn still report synchronization errors. At this time, we can repeat the following operations

git config --global http.proxy socks5://

Scheme 1: replace files
Find / users / gaoxiaoqing / library / caches / homebrew / downloads / 66ff350c21fce7c264e33e3cf6f4995978ac401d5e5047c0ee8dd17e3493a53–m4-1.4.18.mojave.bottle.1.tar.gz and change the name. OK, I guess there are two or two versions of this. The later one will not be generated, but I still can’t sleep after I’m busy. There is the second solution.

Scheme 2: replace homebrew pots

echo 'export HOMEBREW_BOTTLE_DOMAIN=' >> ~/.bash_profile

Brew includes four pieces

Homebrew Source code warehouse
homebrew-core Homebrew core source
homebrew-cask Provides installation of MacOS applications and large binary files
homebrew-bottles Precompiled binary package

If used, you can also change the image

Use the Alibaba cloud image acceleration solution in the next section

Alibaba cloud image acceleration…

When using docker, you need to first download an official image, such asmysqlwordpress。 However, due to network reasons, downloading an official docker image may take a long time, or even fail to download. To this end, Alibaba cloud container mirroring service ACR provides an official mirroring site to speed up the download of official images. Image accelerator is a service for individual developers. It only supports individual development scenarios and is not allowed to be re encapsulated or used for commercial purposes.

# sudo mkdir -p /etc/docker
# sudo tee /etc/docker/daemon.json <<-'EOF'
  "registry-mirrors": [""]
# sudo systemctl daemon-reload
# sudo systemctl restart docker
