1)在项目根目录下创建.npmrc文件(如果已存在就把代码加在下面即可),内容如下 canvas_binary_host_mirror=https://registry.npmmirror.com/-/binary/canvas 这一步非常的重要,就是给npm安装canvas时换个镜像,博主就是在这步卡了很久,最后发现是默认GitHub的源太慢了,导致总是安装失败,法克鱿! 2)ok到这一步终...
node-canvas安装 1.这里推荐使用yarn,npm可能会遇到权限问题,可使用 npm --build-from-source --unsafe-perm install 尝试(百度只搜到这个方法,亲测无效) 2.为防止node-gyp这个大坑的一系列报错和问题 先全局安装node-gyp npm -g node-gyp 3.安装canvas的时候需要从源代码去构建,否则会安装失败或报错,需要在...
安装完依赖后,执行npm install canvas即可。 step 2 画图 通过获取 canvas,可以得到 context 对象,然后就可以像在前端一样绘制图形了 const Canvas = require('canvas'); const canvas = new Canvas(100, 30), ctx = canvas.getContext('2d');
在Windows上部署某些npm包,需要本地编译,有的包环境依赖比较强,比如canvas,基本上在Windows上部署失败都是这个原因,今天带你一次性解决。 安装canvas需要python2.7环境,v3.x.x版本会造成系统报错。 构建node-canvas模块需要: node-gyp的全局安装。 GTK 2 ...
按照他们说的,这个方法在 npm 上还没有,但是 github 这个分支是有的:https://github.com/chearon/node-canvas#12971f64a66b 于是我把这个分支 clone 下来,然后把require('canvas')改成了require('../node-canvas') 运行!Perfect! 泪流满面。。。
编译成功后,在全局模块目录下会存在npm\node_modules\canvas\build\Release\canvas.node文件,在此目录下使用node命令行执行var c = require('canvas');如果输出undefine则编译成功; 到此,不知道你已经踩过几个坑了,反正我踩好些个。 1.由于我之前安装了Python 3.0以上版本,故在node-canvas编译时报错,此错误在错误...
Read more about the problem on Stack Overflow. If you have xcode 10.0 or higher installed, in order to build from source you need NPM 6.4.1 or higher.Quick Exampleconst { createCanvas, loadImage } = require('canvas') const canvas = createCanvas(200, 200) const ctx = canvas.getContext(...
