Question

我使用nvm cookbook来安装nvm和4.3.1版本的Node.js.

include_recipe 'nvm'

nvm_install node['analyzer_agent']['nodejs']['version'] do
  user node['analyzer_agent']['user']['name']
  group node['analyzer_agent']['user']['group']
  from_source false
  alias_as_default true
  action :create
end

当我与用户（在本例中为analyzer_agent）SSH服务器时，一切都按预期工作。我的默认nodej.js版本是4.3.1，当我手动尝试使用npm install pm2 -g安装pm2时，它运行正常。

但是，当我尝试从我的食谱全局安装pm2模块时：

execute "Install PM2" do
    cwd "/home/#{node['analyzer_agent']['user']['name']}"
    user node['analyzer_agent']['user']['name']
    group node['analyzer_agent']['group']
    environment "HOME"=> "/home/#{node['analyzer_agent']['user']['name']}", "USER"=>node['analyzer_agent']['user']['name']
    command "npm install pm2 -g"
    not_if { File.exists?("pm2") }
end

我收到以下错误：

据我所知，在environment内使用execute设置HOME和USER应该可以解决问题。但我没有任何机会。 Chef客户端仅使用已编译的nodejs。不是由nvm安装的那个。

可能出现什么问题？

（顺便说一句，在同一台服务器上，但我和另一个用户从源代码编译了node.js并在全局安装了pm2。我看到它可能与我的问题有关的可能性很小，但是，如果是这样，为什么在我手动在新用户帐户中安装pm2时不会造成任何伤害？）

Answer 1

npm install -g是全局安装，这意味着您需要具有写入安装了Node / NPM的全局文件夹的权限（在本例中为/usr/local/bin）。你可能意味着不使用-g，因为它只存在于人类，而不是工具。

Answer 2

我相信在OpsWorks中，您还可以通过在应用程序的食谱中创建新文件来覆盖已安装的Node版本：attributes/customize.rb。然后：

normal[:opsworks_nodejs][:version] = '4.4.0'

这应该下载正确版本的节点而不是使用Node 0.10 ...因此内置的OpsWorks应用程序运行/监视器（monit）应该可以工作，而不必安装PM2。

如何使Chef客户端使用与NVM一起安装的用户特定nodejs版本？
