Installation

To install prebuilt Electron binaries, use npm. The preferred method is to install Electron as a development dependency in your app:

npm install electron --save-dev

See the Electron versioning doc for info on how to manage Electron versions in your apps.

Global Installation

You can also install the electron command globally in your $PATH:

npm install electron -g

Customization

If you want to change the architecture that is downloaded (e.g., ia32 on an x64 machine), you can use the --arch flag with npm install or set the npm_config_arch environment variable:

npm install --arch=ia32 electron

In addition to changing the architecture, you can also specify the platform (e.g., win32, linux, etc.) using the --platform flag:

npm install --platform=win32 electron

Proxies

If you need to use an HTTP proxy you can set these environment variables.

During installation, the electron module will call out to electron-download to download prebuilt binaries of Electron for your platform. It will do so by contacting GitHub's release download page (https://github.com/electron/electron/releases/tag/v$VERSION, where $VERSION is the exact version of Electron).

If you are unable to access GitHub or you need to provide a custom build, you can do so by either providing a mirror or an existing cache directory.

Mirror

You can use environment variables to override the base URL, the path at which to look for Electron binaries, and the binary filename. The url used by electron-download is composed as follows:

url = ELECTRON_MIRROR + ELECTRON_CUSTOM_DIR + '/' + ELECTRON_CUSTOM_FILENAME

For instance, to use the China mirror:

ELECTRON_MIRROR="https://npm.taobao.org/mirrors/electron/"

Cache

Alternatively, you can override the local cache. electron-download will cache downloaded binaries in a local directory to not stress your network. You can use that cache folder to provide custom builds of Electron or to avoid making contact with the network at all.

Linux: $XDG_CACHE_HOME or ~/.cache/electron/
MacOS: ~/Library/Caches/electron/
Windows: $LOCALAPPDATA/electron/Cache or ~/AppData/Local/electron/Cache/

On environments that have been using older versions of Electron, you might find the cache also in ~/.electron.

You can also override the local cache location by providing a ELECTRON_CACHE environment variable.

The cache contains the version's official zip file as well as a checksum, stored as a text file. A typical cache might look like this:

├── electron-v1.7.9-darwin-x64.zip
  ├── electron-v1.8.1-darwin-x64.zip
  ├── electron-v1.8.2-beta.1-darwin-x64.zip
  ├── electron-v1.8.2-beta.2-darwin-x64.zip
  ├── electron-v1.8.2-beta.3-darwin-x64.zip
  ├── SHASUMS256.txt-1.7.9
  ├── SHASUMS256.txt-1.8.1
  ├── SHASUMS256.txt-1.8.2-beta.1
  ├── SHASUMS256.txt-1.8.2-beta.2
  ├── SHASUMS256.txt-1.8.2-beta.3

Troubleshooting

When running npm install electron, some users occasionally encounter installation errors.

In almost all cases, these errors are the result of network problems and not actual issues with the electron npm package. Errors like ELIFECYCLE, EAI_AGAIN, ECONNRESET, and ETIMEDOUT are all indications of such network problems. The best resolution is to try switching networks, or wait a bit and try installing again.

You can also attempt to download Electron directly from electron/electron/releases if installing via npm is failing.

If installation fails with an EACCESS error you may need to fix your npm permissions.

If the above error persists, the unsafe-perm flag may need to be set to true:

sudo npm install electron --unsafe-perm=true

On slower networks, it may be advisable to use the --verbose flag in order to show download progress:

npm install --verbose electron

If you need to force a re-download of the asset and the SHASUM file set the force_no_cache environment variable to true.
