Index.js 中的语法错误

Question

'use strict';

var path = require('path');
var _ = require('lodash');

function requiredProcessEnv(name) {
if (!process.env[name]) {
throw new Error('You must set the ' + name + ' environment variable');
}
return process.env[name];
}

// All configurations will extend these options
// ============================================
var all = {
env: process.env.NODE_ENV,

// Root path of server
root: path.normalize(__dirname + '/../../..'),

// Server port
port: process.env.PORT || 9000,

// Server IP
ip: process.env.IP || '0.0.0.0',

// Should we populate the DB with sample data?
seedDB: false,

// Secret for session, you will want to change this and make it an  environment variable
secrets: {
session: process.env.session || "wav"
},
// Export the config object based on the NODE_ENV
// ==============================================
module.exports = _.merge(
all,
require('./shared'),
require('./' + process.env.NODE_ENV + '.js') || {})};

当运行使用我的项目（使用 angular-fullstack 创建的网络应用程序）时，我收到以下错误：

Line 39 col 6 Unexpected token: module.exports
                                        ^
line 39  col 7   Expected ':' and instead saw '.'.
  line 42  col 54  Expected '}' to match '{' from line 15 and instead saw ';'.

另外，这段代码也给我的项目带来了一些其他的问题。我将最后几行更改为：

var config = _.merge(...); 
  console.log(config); 
  module.exports = config;`
And I still get a syntax error: ` line 39  col 7   Expected ':' and instead saw 'config'.
  line 39  col 14  Expected an identifier and instead saw '='.
  line 39  col 16  Expected '}' to match '{' from line 15 and instead saw '_'.
  line 39  col 27  Expected an identifier and instead saw ')'.
  line 39  col 27  Expected an identifier and instead saw ')'.
  line 39  col 28  Expected ')' and instead saw ';'.
  line 40  col 15  'config' is not defined.
  line 41  col 20  'config' is not defined.

请学会正确缩进代码。然后您的错误应该 crystal 清晰可见。

'module.export' 在 'all' 对象里面，把它移到外面应该可以：

'use strict';

var path = require('path');
var _ = require('lodash');

function requiredProcessEnv(name) {
    if (!process.env[name]) {
        throw new Error('You must set the ' + name + ' environment variable');
    }
    return process.env[name];
}

// All configurations will extend these options
// ============================================
var all = {
    env: process.env.NODE_ENV,

// Root path of server
    root: path.normalize(__dirname + '/../../..'),

// Server port
    port: process.env.PORT || 9000,

// Server IP
    ip: process.env.IP || '0.0.0.0',

// Should we populate the DB with sample data?
    seedDB: false,

// Secret for session, you will want to change this and make it an  environment variable
    secrets: {
        session: process.env.session || "wav"
    }
};

// Export the config object based on the NODE_ENV
// ==============================================
module.exports = _.merge(
    all,
    require('./shared'),
    require('./' + process.env.NODE_ENV + '.js') || {}
);
