Angular2 QuickStart NPM启动无法正常工作

Question

我知道Angular2 Beta刚刚发布，但是我无法从其官方网站教程（https://angular.io/guide/quickstart）中复制步骤。也许有人遇到过类似的问题，并且知道该怎么做才能解决此问题？当我尝试使用npm start命令启动应用程序时，我得到如下输出：0 info it worked if it ends with ok1 verbose cli [ 'node', '/usr/local/bin/npm', 'start' ]2 info using npm@2.7.43 info using node@v0.12.24 verbose run-script [ 'prestart', 'start', 'poststart' ]5 info prestart angular2-quickstart@1.0.06 info start angular2-quickstart@1.0.07 verbose unsafe-perm in lifecycle true8 info angular2-quickstart@1.0.0 Failed to exec start script9 verbose stack Error: angular2-quickstart@1.0.0 start: `concurrent "npm run tsc:w" "npm run lite" `9 verbose stack Exit status 1279 verbose stack     at EventEmitter.<anonymous> (/usr/local/lib/node_modules/npm/lib/utils/lifecycle.js:213:16)9 verbose stack     at EventEmitter.emit (events.js:110:17)9 verbose stack     at ChildProcess.<anonymous> (/usr/local/lib/node_modules/npm/lib/utils/spawn.js:14:12)9 verbose stack     at ChildProcess.emit (events.js:110:17)9 verbose stack     at maybeClose (child_process.js:1015:16)9 verbose stack     at Process.ChildProcess._handle.onexit (child_process.js:1087:5)10 verbose pkgid angular2-quickstart@1.0.011 verbose cwd /Users/tmrovsky/Documents/angular2/angular2-quickstart12 error Darwin 13.4.013 error argv "node" "/usr/local/bin/npm" "start"14 error node v0.12.215 error npm  v2.7.416 error code ELIFECYCLE17 error angular2-quickstart@1.0.0 start: `concurrent "npm run tsc:w" "npm run lite" `17 error Exit status 12718 error Failed at the angular2-quickstart@1.0.0 start script 'concurrent "npm run tsc:w" "npm run lite" '.18 error This is most likely a problem with the angular2-quickstart package,18 error not with npm itself.18 error Tell the author that this fails on your system:18 error     concurrent "npm run tsc:w" "npm run lite"18 error You can get their info via:18 error     npm owner ls angular2-quickstart18 error There is likely additional logging output above.我有：打字稿1.7.5版本节点0.12.2版本也许有人可以帮助解决问题:)？

Answer 1

从以下位置更改startpackage.json中的字段

"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" "

至

"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "

Answer 2

为了npm start为我运行，我必须确保已全局安装了一些devDependencies。你有没有尝试过：

• npm install -g concurrently

• npm install -g lite-server

• npm install -g typescript

Answer 3

首先，您需要更新npm，lite-server和打字稿：

sudo npm update -g && sudo npm install -g concurrently lite-server typescript

从Angular项目目录中删除node_modules文件夹（如果存在）。下一轮：

npm install

之后，解决ENOSPC错误：

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

最后：

npm start

这是我的package.json文件：
