我在运行 Windows 7 64 位的 Windows 机器上安装node-canvas时遇到问题。我已按照说明进行操作，并且还使用 Visual C++ Professional（试用版）进行了尝试，但这也无济于事。
当我输入npm install canvas时，它给了我以下信息：
npm http GET https://registry.npmjs.org/canvas
npm http 304 https://registry.npmjs.org/canvas
npm http GET https://registry.npmjs.org/canvas/-/canvas-0.13.1.tgz
npm http 200 https://registry.npmjs.org/canvas/-/canvas-0.13.1.tgz
>canvas@0.13.1 install C:\wamp\www\node_modules\canvas
>node-gyp rebuild

（我希望我正确地输入了控制台输出，因为我不得不从控制台中输入它，因为没有找到日志，而且 Windows 显然不允许您将完整的 cmd 输出记录到文件中）
