Question

我正在尝试运行命令 'npm install leaflet-headless' 以便我可以轻松地将传单地图 API 与 Node.js 一起使用。输入此命令后，我收到以下错误：

Answer 1

行 gyp ERR! stack Error: Can't find Python executable "python", you can set the PYTHON env variable. 表示未安装 Python 或告诉 node.js 在何处搜索可执行文件 (python.exe) 的变量未设置。所以请执行以下操作：

1) 安装 Python

2) 在cmd中设置环境变量set PYTHON=C:\{Path to your python install folder}\Python.exe（默认为windows C:\Python27\python.exe）
