'electron-packager' is not recognized as an internal or external command

问题

I recently started using electron. I have successfully completed the 1st phase by creating a hello world app (included files index.html, main.js, package.json). Now I am trying to package the app using electron-packager but getting this error

Steps I have followed:

1. Created a project directory named helloworld.
2. Initialized the project directory using npm init command.
3. Then installed electron using npm install electron --save-dev.
4. Then created the javascript and html files as main.js and index.html respectively.
5. Then used npm start to execute the application.
6. Then installed electron-packager using npm install electron-packager.
7. Now the problem is coming in this step when i am trying to pacakge the app using command electron-packager .

回答1:

Perform a global package install:

npm install -g electron-packager

The -g flag tells NPM to install the package globally which makes the command electron-packager available in your PATH.

If you don't want to do a global install you can install it locally and run with npx.

npm install -D electron-packager 

npx electron-packager .

---

Alternatively, you can reference it straight from the node_modules folder (not recommended).

./node_modules/electron-packager/cli.js

If you have installed it locally with:

npm install electron-packager

Then, it's not gonna work, install it globally as a cli:

npm install -g electron-packager

You can also get it through:

"node_modules/electron-packager/cli.js" . --all --asar

After All, if you don't get it working, install electron-packager. Then, go to your package.json. And beneath your start scripts. Make another string named "build" and give it a value of the electron-packager command you want to run:

...
    "scripts": {
    "start": "electron .",
    "build": "electron-packager . --asar --all"
  },
...

Then, go in command prompt or terminal or bash. Then, type:

npm run build

There are two cases to make it work...

1. as discussed above, install electron globally using -g, i.e. using npm install -g electron-packager

2. change in your package.json, "scripts": { "start": "electron-packager ." }, and then give command npm start.

This way it worked for me..

回答4:

You've to install electron-packager globally, that's why it shows 'electron-packager' is not recognized as an internal or external command

For this, you have to install electron-package globally

You can install globally by using -g option.

Example:- npm install -g electron-packager OR npm i -g electron-packager //i stands for install

I might be totally off with it but my fix was that I put the dot without space just make sure in you package.json file its "start": "electron ." Fixed it for me at least
