node-canvas模块有问题
发布于 10 年前 作者 yihuaxiang 9984 次浏览 最后一次编辑是 8 年前

我在github下载了node-canvas模块的代码，运行了自带的例子clock.js,结果： module.js:340 throw err; ^ Error: Cannot find module '…/build/Release/canvas’ at Function.Module._resolveFilename (module.js:338:15) at Function.Module._load (module.js:280:25) at Module.require (module.js:364:17) at require (module.js:380:17) at Object.<anonymous> (/home/fdd/node_modules/node-canvas/lib/bindings.js:2:18) at Module._compile (module.js:456:26) at Object.Module._extensions…js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17)

为什么会有错误？官网的东西，不应该有错啊？

代码是我通过git clone方式获取的，运行前需不需要进行npm install安装啊？

需要 npm install

@jiangli373 我进行了npm install之后还是有那个错误。

node-canvas 下有个install文件，这个怎么用啊？（是用这个安装吗？）

@yihuaxiang Node canvas is a Cairo backed Canvas implementation for NodeJS 应该需要安装Cairo http://cairographics.org/

@jiangli373 安装了的， 18:38 fdd@fdd:~ $sudo apt-get install libcairo2-dev [sudo] password for fdd: 正在读取软件包列表… 完成 正在分析软件包的依赖关系树
正在读取状态信息… 完成
libcairo2-dev 已经是最新的版本了。

Install Node-Canvas on Ubuntu

@bnuhero 前面都正常，但是到了sudo npm install canvas 时：

19:01 fdd@fdd:~ $sudo npm install canvas

canvas@1.1.6 install /home/fdd/node_modules/canvas node-gyp rebuild

其实我个人觉得node-canvas是比较难装的包，依赖各种各种

@yaochun 那有什么好用的类似canvas处理照片的包不？

@yihuaxiang node-images 可以参考 http://liteneo.com/2014/06/23/mosaic-mode/

@yihuaxiang

$ sudo apt-get install libcairo2-dev libjpeg8-dev libpango1.0-dev libgif-dev build-essential g++的安装正常吗？另外你用的什么版本的Ubuntu和Python？

我在Ubuntu 14.04下安装，没遇到问题。

我自己项目用过的qr-image，没有依赖，支持utf-8推荐给你
