我有一個terraform腳本來站起來一個EC2實例，它安裝git，nvm，node，並從github安裝一個angular2倉庫。Terraform user_data ng build
# install angular cli globally
npm install -g @angular/cli &> globalCli.log
cd test
# install node_modules
npm install &> npmInstall.log
# create dist folder
ng build --output-path 'dist' >& ngBuild.log
ng update >& ngUpdate.log
#start the app
(npm start) &> npmStart.log```
出於某種原因，terrform腳本返回該錯誤ngBuild.log

奇怪的是，如果我ssh到EC2實例，並運行相同的ng build命令，它工作正常。
任何想法？
