I used nvm to download node v0.4.10 and installed npm to work with that version of node.
我使用nvm下载节点v0.4.10，并安装npm来使用该版本的节点。
I am trying to install express using
我正在试着安装快递。
npm install express -g
and I get an error that express requires node version >= 0.5.0.
我得到一个表示需要节点版本>= 0.5.0的错误。
Well, this is odd, since I am following the directions for a node+express+mongodb tutorial here that used node v0.4.10, so I am assuming express is/was available to node v0.4.10. If my assumption is correct, how do I tell npm to fetch a version that would work with my setup?
这很奇怪，因为我正在遵循使用节点v0.4.10的node+express+mongodb教程的方向，所以我假设express对节点v0.4.10可用。如果我的假设是正确的，我如何告诉npm获取一个与我的设置兼容的版本?

If you have to install an older version of a package, just specify it
如果您必须安装包的旧版本，只需指定它
npm install <package>@<version>
For example: npm install express@3.0.0
例如:npm安装express@3.0.0。
You can also add the --save flag to that command to add it to your package.json dependencies, or --save --save-exact flags if you want that exact version specified in your package.json dependencies.
还可以将-save标志添加到该命令中，以便将其添加到包中。如果您希望在包中指定确切的版本，那么可以使用json依赖项，或者——保存——精确标志。json依赖性。
The install command is documented here: https://docs.npmjs.com/cli/install
这里记录了安装命令:https://docs.npmjs.com/cli/install
If you're not sure what versions of a package are available, you can use:
如果您不确定一个包有什么版本，您可以使用:
npm view <package> versions
And npm view can be used for viewing other things about a package too. https://docs.npmjs.com/cli/view
npm视图也可以用来查看包的其他内容。https://docs.npmjs.com/cli/view

It's quite easy. Just write this, for example:
这很容易。写下来，例如:
npm install -g npm@4.6.1
Or:
或者:
npm install -g npm@latest // For the last stable version
npm install -g npm@next // For the most recent release

First remove old version, then run literally the following:
首先删除旧版本，然后按字面意思运行:
npm install express@3.X
