我可以在IBM Bluemix DevOps Services中使用不同版本的节点，构建“npm”构建器类型？

Question

我正在构建一个应用程序应用程序，然后将它打包成WAR文件以部署到Liberty运行时。

该构建过程会警告我，ember-cli将停止使用节点v0.10.29，并建议使用节点0.12。

我可以在：DevOps Services，构建步骤'npm'构建器类型中使用不同版本的节点吗？

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

Could not find watchman, falling back to NodeWatcher for file system events. Visit http://www.ember-cli.com/#watchman for more info.

v0.10.29是构建映像上存在的唯一节点版本。为了使用不同的版本，用户必须下载它。这里是一个示例脚本如何做到这一点

#!/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指定哪些节点版本？ Bluemix支持所有当前可用的节点版本，请参阅“Node.js运行时版本”下的the docs以获取更多信息。继续并在package.json中指定所需的版本为engines属性，您应该没问题。
