我在Windows 7上使用VS 2017和.NET Core 2。 尝试按照这些说明创建一个新的.NET Core 2.0和Angular应用程序。
运行最新版本的node和npm：
node -v > v10.1.0
npm -v > v6.0.1
根据指示，我开始构建应用程序，但出现了“找不到Python”的错误。我检查了环境变量，路径中有Python。不确定为什么找不到。
构建似乎“半成品”，已经解决了一些依赖项。第二次尝试构建应用程序时，出现了JavaScript运行时错误...我认为这是由于第一次糟糕的构建任务导致的。
我还尝试在ClientApp文件夹中运行“npm install”，但出现了相同的错误“找不到Python”。
如果能得到任何帮助将不胜感激！
