我可以在IBM Bluemix DevOps Services中使用不同版本的節點，構建「npm」構建器類型？

Question

我正在構建一個應用程序應用程序，然後將它打包成WAR文件以部署到Liberty運行時。

該構建過程會警告我，ember-cli將停止使用節點v0.10.29，並建議使用節點0.12。

我可以在：DevOps Services，構建步驟'npm'構建器類型中使用不同版本的節點嗎？

Future versions of Ember CLI will not support v0.10.29. Please update to Node 0.12 or io.js. version: 0.2.7 1.13.8

v0.10.29是構建映像上存在的唯一節點版本。爲了使用不同的版本，用戶必須下載它。這裏是一個示例腳本如何做到這一點

#!/bin/bash 
node_version=v0.12.7 
install_name=node-v0.12.7-linux-x64 
if [ ! -e $install_name.tar.gz ]; then 
wget "http://nodejs.org/dist/$node_version/$install_name.tar.gz" 
echo 'Untarring' 
tar xf $install_name.tar.gz 
fi 
NODE_12_INSTALL_DIR=`pwd`/$install_name/bin 
PATH=$NODE_12_INSTALL_DIR:$PATH 
node -v

你在你的package.json指定哪些節點版本？ Bluemix支持所有當前可用的節點版本，請參閱「Node.js運行時版本」下的the docs以獲取更多信息。繼續並在package.json中指定所需的版本爲engines屬性，您應該沒問題。
