Question

我正在尝试从nodejs向kafka代理发布消息。当我尝试在nodejs窗口中安装kafka-node模块时。我得到了与python相关的异常。

 C:\Program Files\nodejs>npm install kafka-node

kafka-node和python之间是否有任何关系。我已经设置了python 3.4并再次尝试安装kafka-node模块，它说gyp不支持python3.4版本。（以下是错误消息）

所以我安装了python 2.6并再次尝试再次安装kafka-node，它给出了以下错误

任何帮助表示赞赏。谢谢

Answer 1

您第二次尝试时恢复的错误是：

MSBUILD：错误MSB3428：无法加载Visual C ++组件“VCBuild.exe”。为了解决这个问题，1）ins 高大的.NET Framework 2.0 SDK，2）安装Microsoft Visual Studio 2005或3）添加位置系统路径的组件，如果它安装在别处。

您是否安装了安装了C ++编译器的Visual Studio？如果没有，你应该安装它。

Answer 2

node-gyp用于构建snappy依赖项。压缩库。如果你不在kafka消息中使用压缩，你可以放心地忽略它。在版本0.3.3中，此依赖项是可选的。

如果您不使用snappy，只需使用--no-optional标志安装模块：

npm install kafka-node --no-optional
