如何診斷「npm start」的失敗？

Question

我正在學習AngularJS。爲此，我遵循tutorial並檢出了示例代碼（git clone --depth=14 https://github.com/angular/angular-phonecat.git）。然後，我跑了npm install和npm install -g bower。

最後，我試圖用npm start啓動web服務器。

它沒有工作，我得到了下面的錯誤輸出：

0 info it worked if it ends with ok 
1 verbose cli [ 'C:\\Program Files\\nodejs\\\\node.exe', 
1 verbose cli 'C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js', 
1 verbose cli 'start' ] 
2 info using npm@1.4.28 
3 info using node@v0.10.33

10 error Failed at the angular-phonecat@0.0.0 prestart script. 
10 error This is most likely a problem with the angular-phonecat package, 
10 error not with npm itself. 
10 error Tell the author that this fails on your system: 
10 error  npm install 
10 error You can get their info via: 
10 error  npm owner ls angular-phonecat 
10 error There is likely additional logging output above. 
11 error System Windows_NT 6.1.7601 
12 error command "C:\\Program Files\\nodejs\\\\node.exe" "C:\\Program Files\\nodejs\\node_modules\\npm\\bin\\npm-cli.js" "start" 
13 error cwd D:\dev\js-learning\angular-phonecat 
14 error node -v v0.10.33 
15 error npm -v 1.4.28 
16 error code ELIFECYCLE 
17 verbose exit [ 1, true ] 

我怎樣才能解決呢？

Answer 1

只要做到：

npm install 

然後：

npm start 

然後打開瀏覽器，瀏覽到：

http://localhost:8000 

然後選擇/應用程序，你會被帶到：

http://localhost:8000/app/#/phones 

如果你仍然有問題，你可以做以下事情，只是爲了讓應用程序在沒有測試的情況下運行。

npm install express --save 

請將以下代碼保存爲server.js到根：

var express = require('express'); 
var http = require('http'); 
var app = express();   

app.set('port', process.env.PORT || 8000); 
app.use(express.static(__dirname + '/app')); 

var server = http.createServer(app); 

server.listen(app.get('port'), function() { 
    console.log('Express HTTP server listening on port ' + app.get('port') ) ; 
}); 

然後做：

node server.js 

現在瀏覽：

http://localhost:8000
