当我尝试运行npm install时出错

Question

I'm just trying to do the first angular.js tutorial on the official website. When I try to run npm install from my project directory I get the following error.

My package.json file is given below.

 { "version": "0.0.0", "private": true, "name": "angular-phonecat", "description": "A tutorial application for AngularJS", "repository": "https://github.com/angular/angular-phonecat", "license": "MIT", "devDependencies": { "karma": "^0.12.16", "karma-chrome-launcher": "^0.1.4", "karma-jasmine": "^0.1.5", "protractor": "~1.0.0", "http-server": "^0.6.1", "tmp": "0.0.23", "bower": "^1.3.1", "shelljs": "^0.2.6" }, "scripts": { "postinstall": "bower install", "prestart": "npm install", "start": "http-server -a 0.0.0.0 -p 8000", "pretest": "npm install", "test": "node node_modules/karma/bin/karma start test/karma.conf.js", "test-single-run": "node node_modules/karma/bin/karma start test/karma.conf.js --single-run", "preupdate-webdriver": "npm install", "update-webdriver": "webdriver-manager update", "preprotractor": "npm run update-webdriver", "protractor": "protractor test/protractor-conf.js", "update-index-async": "node -e \\"require('shelljs/global'); sed('-i', /\\\\/\\\\/@@NG_LOADER_START@@[\\\\s\\\\S]*\\\\/\\\\/@@NG_LOADER_END@@/, '//@@NG_LOADER_START@@\\\\n' + cat('bower_components/angular-loader/angular-loader.min.js') + '\\\\n//@@NG_LOADER_END@@', 'app/index-async.html');\\"" } } 

Can someone help me to solve this problem. Thanks.

Answer 1

The messages are warnings, sometimes that just happens, and they often are uneeded anyway.
As long as the main components, Bower, Protractor, Karma etc are working, then I would try just carry on with the tutorial.

You can test they are working by running their commands, eg

./node_modules/.bin/bower help 

But

I think one issue I had with npm and running those commands is that they dont just run like the angular tutorial says.
So where the tutorial says, run this:

protractor test/protractor-conf.js

You might have to modify the command to this

./node_modules/.bin/protractor test/protractor-conf.js

Same with bower, karma etc

eg

put this in front of the commands

./node_modules./bin

the ./ says run this as a script and the path is so you access the scripts in the node_modules/.bin directories

Update
If you want to run a karma test:
First, make sure you are in the root directory of the project

./node_modules/.bin/karma start test/karma.conf.js  --single-run
