If you want to install the app from a pre-built version on the release page, you can simply run the executable after download.

For updating, simply download the new version and copy it over the old one (keep a backup of the old one if you want to be sure).

In order to install from .zip files, please install libgconf2-4 first:

apt-get install libgconf2-4

The data folder for Mist depends on your operating system:

• Windows %APPDATA%\Mist
• macOS ~/Library/Application\ Support/Mist
• Linux ~/.config/Mist

For development, a Meteor server assists with live reload and CSS injection.

Once a Mist version is released the Meteor frontend part is bundled using the meteor-build-client npm package to create pure static files.

To run mist in development you need:

• Node.js v7.x (use the preferred installation method for your OS)
• Meteor javascript app framework
• Yarn package manager

Install the latter ones via:

$ curl https://install.meteor.com/ | sh
$ curl -o- -L https://yarnpkg.com/install.sh | bash

Now you're ready to initialize Mist for development:

$ git clone https://github.com/ethereum/mist.git
$ cd mist
$ git submodule update --init --recursive
$ yarn

For development we start the interface with a Meteor server for auto-reload etc.

Start the interface in a separate terminal window:

$ yarn dev:meteor

In the original window you can then start Mist with:

$ cd mist
$ yarn dev:electron

NOTE: Client binaries (e.g. geth) specified in clientBinaries.json will be checked during every startup and downloaded if out-of-date, binaries are stored in the config folder.

NOTE: use --help to display available options, e.g. --loglevel debug (or trace) for verbose output

Start the wallet app for development, in a separate terminal window:

$ yarn dev:meteor

In another terminal:

$ cd my/path/meteor-dapp-wallet/app && meteor --port 3050

In the original window you can then start Mist using wallet mode:

$ cd mist
$ yarn dev:electron --mode wallet

This is useful if you are already running your own node or would like to connect with a private or development network.

$ yarn dev:electron --rpc path/to/geth.ipc

You can pass command-line options directly to Geth by prefixing them with --node- in the command-line invocation:

$ yarn dev:electron --mode mist --node-rpcport 19343 --node-networkid 2

The --rpc Mist option is a special case. If you set this to an IPC socket file path then the --ipcpath option automatically gets set, i.e.:

$ yarn dev:electron --rpc path/to/geth.ipc

...is the same as doing...

$ yarn dev:electron --rpc /my/geth.ipc --node-ipcpath /path/to/geth.ipc

If you would like to quickly set up a local private network on your computer, run:

geth --dev

Look for the IPC path in the resulting geth output, then start Mist with:

$ yarn dev:electron --rpc path/to/geth.ipc

Our build system relies on gulp and electron-builder.

Cross-platform builds require additional dependencies needed by Electron Builder. Please follow their instructions for up to date dependency information.

To generate the binaries for Mist run:

$ yarn build:mist

To generate the Ethereum Wallet:

$ yarn build:wallet

The generated binaries will be under dist_mist/release or dist_wallet/release. Starting from 0.11.0, both Ethereum Wallet and Mist ships with a meteor-dapp-wallet instance (https://github.com/ethereum/meteor-dapp-wallet).

To build binaries for specific platforms (default: all available) use the following flags:

$ yarn build:mist --mac      # mac
$ yarn build:mist --linux    # linux
$ yarn build:mist --win      # windows

When building a binary, you can optionally skip some tasks — generally for testing purposes.

$ yarn build:mist --mac --skipTasks=build-interface,release-dist

Prints the SHA-256 checksums of the distributables.

It expects installer/zip files to be in the generated folders e.g. dist_mist/release

$ yarn task checksums [--wallet]

Any other gulp task can be run using yarn task.

$ yarn task clean-dist

Tests run using Spectron, a webdriver.io runner built for Electron.

First make sure to build Mist with:

$ yarn build:mist

Then run the tests:

$ yarn test:unit:once
$ yarn test:e2e

Note: Integration tests are not yet supported on Windows.
