提问by Karl Cassar
I've been trying to install PreRender.Ioon my local machine to test. I've installed Python 2.7.10. When I type:
我一直在尝试安装PreRender.Io在我的本地机器上进行测试。我已经安装了 Python 2.7.10。当我输入：
npm install prerender
npm install prerender
It gives an error:

I couldn't locate CL.exe, and a quick search on Google seems to be some missing Visual C++ compiler. However, I tried installing say VC++ 2008 redistributable x86, but still same problem.
我找不到 CL.exe，在 Google 上快速搜索似乎缺少一些 Visual C++ 编译器。但是，我尝试安装说 VC++ 2008 可再发行的 x86，但仍然存在同样的问题。
Any idea what could be wrong? OS is Windows 7 64-bit.
知道有什么问题吗？操作系统是 Windows 7 64 位。

I've managed to solve the problem, although it was quite strange. Honestly, I'm not sure which one solved it completely as I've done quite some stuff. I had installed Visual Studio 2015 on my machine. Below is a summary of what I've done:
我设法解决了这个问题，虽然这很奇怪。老实说，我不确定哪一个完全解决了它，因为我已经做了很多事情。我已经在我的机器上安装了 Visual Studio 2015。下面是我所做的总结：
Installed Visual C++ Compiler, from the VS 2015 installation. By default it was unticked. I think this is what fixed the issue.
Added the path where CL.exe
(C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin)and stdlib.h(C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include)are located to the PATHenvironment variable.- Executed the
npm install prerenderfrom theDeveloper Command Promptin of Visual Studio 2015, running in Administrator mode
从 VS 2015 安装安装Visual C++ Compiler。默认情况下它是未选中的。我认为这就是解决问题的原因。
将CL.exe
(C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin)和stdlib.h所在的路径添加(C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\include)到PATH环境变量中。- 执行
npm install prerender从Developer Command Prompt在Visual Studio 2015年，在运行管理模式

I'm just going through an Angular JS tutorial and had this issue, but their docs suggest it isn't a problem:
我正在阅读 Angular JS 教程并遇到了这个问题，但他们的文档表明这不是问题：
"We often see an npm WARN message after a series of gyp ERR! messages. Ignore them. A package may try to re-compile itself using node-gyp. If the re-compile fails, the package recovers (typically with a pre-built version) and everything works."
“我们经常在一系列 gyp ERR! 消息之后看到 npm WARN 消息。忽略它们。一个包可能会尝试使用 node-gyp 重新编译自己。如果重新编译失败，包会恢复（通常带有预内置版本），一切正常。”

For me the problem came after installing a new version of node. npm install would show the error above. Then I got the error above but not for the package PreRender.Io but for gulp-sass, though I believe the problem has the same root. To solve it, I installed the previous version of node I'd been using (6.9.5) and then I used nvm to manage node versions as described here: https://www.sitepoint.com/quick-tip-multiple-versions-node-nvm/
对我来说，问题是在安装新版本的节点后出现的。npm install 会显示上面的错误。然后我得到了上面的错误，但不是针对 PreRender.Io 包，而是针对 gulp-sass，尽管我相信问题有相同的根源。为了解决这个问题，我安装了我一直在使用的以前版本的节点（6.9.5），然后我使用 nvm 来管理节点版本，如下所述：https://www.sitepoint.com/quick-tip-multiple-版本-节点-nvm/
Switching to the previous version of node using nvm meant I could do npm install without having to install a large SDK I wasn't going to end up using.
使用 nvm 切换到以前版本的 node 意味着我可以执行 npm install ，而无需安装我最终不会使用的大型 SDK。
