Install docker
. It is recommended to follow the instructions from the
official site.
Installing docker
via snap
or from the default repository can cause troubles.
You need to install both docker
and docker-compose
.
Note: On linux you may encounter the following error when you’ll try to work with zksync
:
ERROR: Couldn't connect to Docker daemon - you might need to run `docker-machine start default`.
If so, you do not need to install docker-machine
. Most probably, it means that your user is not added to
thedocker
group. You can check it as follows:
docker-compose up # Should raise the same error.
sudo docker-compose up # Should start doing things.
If the first command fails, but the second succeeds, then you need to add your user to the docker
group:
sudo usermod -a -G docker your_user_name
After that, you should logout and login again (user groups are refreshed after the login). The problem should be solvedat this step.
If logging out does not help, restarting the computer should.
- Install
Node
(requires version 14.14.0 or higher). Since our team attempts to always use the latest LTS version ofNode.js
, we suggest you to install nvm. It will allow you to updateNode.js
version easily in the future. - Install
yarn
. Instructions can be found on the official site. Check ifyarn
is installed by runningyarn -v
.If you face any problems when installingyarn
, it might be the case that your package manager installed the wrong package.Make sure to thoroughly follow the instructions above on the official website. It contains a lot of troubleshootingguides in it. - Run

Install axel
for downloading keys:
On mac:
brew install axel
On debian-based linux:
sudo apt-get install axel
Check the version of axel
with the following command:
axel --version
Make sure the version is 2.17.10
.
Install the latest rust
version.
Instructions can be found on the official site.
Verify the rust
installation:
rustc --version
rustc 1.48.0 (7eac88abb 2020-11-16)
Optionally, you may want to optimize the build time with the LLVM linker, lld
. Make sure you have it installed and
append "-C", "link-arg=-fuse-ld=lld"
to the rustflags
in your .cargo/config
file, so it looks like this:
[target.x86_64-unknown-linux-gnu]
rustflags = [
"-C", "link-arg=-fuse-ld=lld",
]
Warning: This is only viable for linux since lld
doesn’t work on mac.
Install psql
CLI tool to interact with postgres.
On debian-based linux:
sudo apt-get install postgresql-client
Install [diesel](https://diesel.rs/)
CLI (it is used for migrations management only):

If at the install step you get the linkage errors, install the development version of libpq
.
On debian-based linux:
sudo apt-get install libpq-dev
If you still see the errors, install the build-essential
package. On debian-based linux:
sudo apt install build-essential
Also, we need [sqlx](https://github.com/launchbadge/sqlx)
CLI (it is used to generate database wrappers):
cargo install --version=0.2.0 sqlx-cli
If you face an error Could not find directory of OpenSSL installation
, then you should do the following.
Theinstruction is targeted on debian-based Linux, but generally, the steps are similar for all OS.
- Install
libssl-dev
:
sudo apt install libssl-dev
- Install OpenSSL. Here is the instruction for Ubuntu, but thesteps should be similar for the debian-based Linux distros.
- Add
OPENSSL_DIR
variable to your environment. This would typically be/usr/local/ssl
. You can do this by addingthe following line to your shell profile file (e.g.~/.bash_profile
):
export OPENSSL_DIR=/usr/local/ssl
- Install
package-config
:
sudo apt-get install -y pkg-config
You have to install solc

brew install solidity@5
If you're Arch user, download the archived version from here and install it
pacman -U solidity-0.5.14-1-x86_64.pkg.tar.xz
Finally, to prevent pacman from upgrading it, add this line to your /etc/pacman.conf
IgnorePkg = solidity
