Installation

$ npm install

=> Note that you need to rebuild modules for electron after pre-step

# for windows
$ .\node_modules\.bin\electron-rebuild.cmd
# for linux
$ ./node_modules/.bin/electron-rebuild

Run it

$ npm start

Possible errors

• Error: A dynamic link library (DLL) initialization routine failed

两个可能有用的链接：issues#10193, using-native-node-modules, 注意只有在dependencies中的modules才会被rebuild，还是失败的话检查一下package.json文件有没有写对

• How to use sloc and js-ipfs modules with Electron

两个可能有用的链接：solc#using-with-electron, electronjs.org/docs/faq

• npm install build ERROR MSB4019

可以参考这个链接：npm-install-g-karma-error-msb4019-the-imported-project-c-microsoft-cpp-defau

• An unhandled error occurred inside electron-rebuild

两个可能有用的链接：compiling-native-addon-modules,node-gyp#installation, 另外检查路径中不要有中文。

Sometimes electron-rebuild results in an error like openssl/rsa.h: No such file. For Ubuntu and other Debian based systems run the following command to fix the problem sudo apt-get install libssl-dev

For Windows systems, first download and install openSSL libraries from here. Then edit the following file .\node_modules\ursa-optional\binding.gyp Change the contents of the file to:

{
  "targets": [
    {
      'target_name': 'ursaNative',
      'sources': [ 'src/ursaNative.cc' ],
      'conditions': [
        [ 'OS=="win"', {
          'defines': [
            'uint=unsigned int',
          ],
          'include_dirs': [
            # use node's bundled openssl headers platforms
            'C:\Program Files\OpenSSL-Win64\include',
                        "<!(node -e \"require('nan')\")"
          ],
          'libraries': [
            '-lC:/Program Files/OpenSSL-Win64/lib/capi.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/dasync.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/libapps.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/libcrypto.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/libssl.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/libtestutil.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/openssl.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/ossltest.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/padlock.lib',
            '-lC:/Program Files/OpenSSL-Win64/lib/uitest.lib'
          ]
        }, { # OS!="win"
          'include_dirs': [
            # use node's bundled openssl headers on Unix platforms
            '<(node_root_dir)/deps/openssl/openssl/include',
                        "<!(node -e \"require('nan')\")"
          ],
        }],
      ],
    }
  ]
}

Please note: The installation directory of OpenSSL should match with the path given in the above file.

• Sweetalert2 text input not clickable/focus when bootstrap modal is open

This link is helpful to solve it: issues#374

• Raise the exceed gas limit error

Just increase the upper bound of gas limit for testrpc or geth client, here I set limit gas to 100000000.
