Windows上找不到可执行的Python
使用node-canvas组件找不到python运行环境
canvas这个组件很强大，H5、小程序、node都可以使用它。但node环境下还是需要满足特定的条件才能使用node-canvas的，在windows系统中，安装node-canvas前需要有python环境，否则直接安装canvas可能会出现如下错误：
gyp ERR! configure error gyp ERR! stack Error: Can't find Python executable "C:\Users\<youruser>\AppData\Local\Programs\Python\Python37-32\python.EXE", you can set the PYTHON env variable. gyp ERR! stack at PythonFinder.failNoPython (C:\<project-path>\node_modules\node-gyp\lib\configure.js:483:19) gyp ERR! stack at PythonFinder.<anonymous> (C:\<project-path>\node_modules\node-gyp\lib\configure.js:508:16) gyp ERR! stack at C:\<project-path>\node_modules\graceful-fs\polyfills.js:284:29 gyp ERR! stack at FSReqWrap.oncomplete (fs.js:158:21taggerscript问题就是出在Node 在系统中找到不Python的环境变量。
- (可选) 从官网安装Python：https://www.python.org/
- 打开命令行，以管理员的身份运行以下命令安装 VS Build Tools 和 Python 2.7
npm install --global --production windows-build-tools安装windows-build-tools成功后会显示：
全局安装node-gyp：
npm install node-gyp大功告成。重启命令行，重新安装node-canvas包，应该就没有什么问题了。
