Node.js：SyntaxError：意外令牌：编译ejs时

Question

I am trying to apply filter to EJS using Node.JS and I am getting the below error. I want the message content to be displayed in uppercase.

D:\Apps\Templating\ejs>node server.js
D:\Apps\node_modules\ejs\lib\ejs.js:470
      throw e;
            ^
SyntaxError: Unexpected token : while compiling ejs

    at Module.load (module.js:355:32)
    at Function.Module._load (module.js:310:12)

This is my code- server.js:

var ejs = require('ejs');
var template = "<%=: message | upcase %>";
console.log(ejs.render(template,{message : 'hello ejs with filter'}));

I have installed ejs using the package manager and it is working for normal scripts with out filters(:). EJS version downloaded is the latest- 2.3.3 and node version is 0.12.4.

npm install ejs

Any help will be appreciated. Thanks in advance.

Answer 1

当前版本的ejs （v2.3.3）不支持过滤器，该过滤器已从版本2中删除。如果要使用过滤器，则需要安装1.x版本：

$ npm i ejs@1.x

Answer 2

I found out this now. EJS made some changes from version 2 onwards including removal of filter feature. https://github.com/tj/ejs

在ejs v2中，必须放置不带=或-如果存在正常的代码或函数，则不带对象，而如果具有必须以=或-开始的对象，则不带对象-符合Express视图系统中间JavaScript的静态缓存未缓冲的代码为条件语句等<% code %>逃逸HTML默认使用<%= code %>未逸出具有缓冲<%- code %>支持设计者喜欢的模板标签的定制过滤器支撑件包括客户端支持换行与啜<% code -%>或<% -%>或<%= code -%>或<%- code -%>在此处查看更多信息： https : //github.com/tj/ejs
