Question

我一直在使用node-wit v3.3.2 今天，我想更新并使用最新版本。

但是我无法导入node-wit。不知道为什么。我只是复制了他们文档中给出的代码。

'use strict'
var MY_TOKEN="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

const {Wit, log} = require('node-wit');

const client = new Wit({
accessToken: MY_TOKEN,
actions: {
send(request, response) {
return new Promise(function(resolve, reject) {
console.log(JSON.stringify(response));
return resolve();
});
},
myAction({sessionId, context, text, entities}) {
console.log(Session ${sessionId} received ${text});
console.log(The current context is ${JSON.stringify(context)});
console.log(Wit extracted ${JSON.stringify(entities)});
return Promise.resolve(context);
}
},
logger: new log.Logger(log.DEBUG) // optional
});

终端显示：

const {Wit, log} = require('node-wit');
^

可能是您正在使用的节点版本。使用较低版本时，您需要使用标记--harmony_destructuring。

取自：https://github.com/wit-ai/node-wit

# Node.js <= 6.x.x, add the flag --harmony_destructuring
node --harmony_destructuring examples/basic.js <MY_TOKEN>
# Node.js >= v6.x.x
node examples/basic.js <MY_TOKEN>

无法使用node-wit
