node-canvas模块有问题
发布于 6个月前 作者 yihuaxiang 684 次浏览

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。

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

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

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

$ 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
