我正在尝试运行命令'npm install leaflet-headless'，因此我可以轻松地使用带有Node.js的传单映射API。输入此命令后，我收到以下错误：

The line gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable. mean that either Python is not installed or the variable to tell node.js where to search for the executeable (python.exe) is not set. So do the following:

线路gyp ERR！ stack错误：找不到Python可执行文件“python”，可以设置PYTHON env变量。意味着没有安装Python或者告诉node.js的变量在哪里搜索可执行文件（python.exe）没有设置。所以做以下事情：

1) Install Python

1）安装Python

2) Set the evironment variable in the cmd set PYTHON=C:\{Path to your python install folder}\Python.exe (Default on windows C:\Python27\python.exe)

2）在cmd集中设置环境变量PYTHON = C：\ {python安装文件夹的路径} \ Python.exe（Windows C上的默认值：\ Python27 \ python.exe）
