Question

在Ubuntu 17.10上我正在安装和运行这样的电子：

    ole@mki:~/angular-electron$ npm i --save-dev electron

    > electron@1.7.12 postinstall /home/ole/angular-electron/node_modules/electron
    > node install.js

    npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@1.1.3 (node_modules/fsevents):
    npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for fsevents@1.1.3: wanted {"os":"darwin","arch":"any"} (current: {"os":"linux","arch":"x64"})

    + electron@1.7.12
    updated 1 package in 19.956s
    ole@mki:~/angular-electron$ electron
    electron: command not found

安装后Ubuntu无法找到电子命令。想法？

Answer 1

When running npm i --save-dev electron the package will be installed in /home/ole/angular-electron/node_modules/electron (as you can see). To execute the binary you need to run /home/ole/angular-electron/node_modules/.bin/electron or $(npm bin)/electron.

I propose that you'll add a script in your package.json to run electron, for example:

"scripts": {
  "start": "electron"
}

npm will then automatically look into node_modules/.bin.

This might be a little bit confusing but in general, there are 2 ways how to run npm packages.

You can install the package globally npm install your-package-name -g
You can install the package locally npm install your-package-name and then run it from /node_modules/.bin/electron

If you install your package locally you have also two options how to run the package from command line:

Directly from node_modules like this: ../node_modules/.bin/electron
You can create a script command in your

package.json:

"scripts": {
  "your-script-name": "electron"
}

then if you run npm run your-script-name npm will first look in the .bin directory and if it finds electron it will run it. Otherwise it will look at your global dependencies.

However, it is important not to forget that this command:

"your-script-name": "do-something && electron"

will also run electron globally. If you want to run electron locally you can either split the command into two separate commands or change electron to npm run electron like this:

"your-script-name": "do-something && npm run electron"

使用电子作为npm dev依赖于Ubuntu
