[Vue warn]: Error in render: “TypeError: Cannot read properties of undefined

e.g.

<div>{{obj.name}}</div>
<div>{{obj.info.access_control}}</div>

data(){
	return {
		obj:{}
	}
}

The data format of template rendering is obj.name or obj.info.access_ Control, why does obj.name not report the above dislocation and obj.info.access_ The above error will appear in control. Because obj data has not been requested from the back end to assign its value, the obj object is still an empty object. Without the attribute info, obj.info is naturally undefined, and then undefined.access_ Control will naturally report the above error.

Solution: add info null object in obj object

data(){
	return {
		obj:{
			info:{}
		}
	}
}

chunk-vendors.7142f8da.js:1 Uncaught SyntaxError: Unexpected token ‘＜‘

This is what I Vue found by previewing with serve – s dist after packaging

reason There is a problem with the parameters configured in vue.config.js

    publicPath: process.env.NODE_ENV === 'production'
    ?'/execl_forward/'
    : '/'

Then use NPM run build to package

Cause static file error

So I created EXECL in dist_ Forward folder put CSS and JS folders in it

Then it was solved

Or use the default packaging method

Vue.config.js

publicPath: './'

Vue Error in v-on handler: “TypeError: path.indexOf is not a function“

reason:

My path is written like this

@click="openBlank({ path: '/reissue'},{historyOpinion:ho})"

It belongs to non-standard writing Just change it to this

@click="openBlank('/reissue',{historyOpinion:ho})"

Please note that the module “sacrableu” has no “compute blue” attribute

Recently, I encountered the following errors when installing fairseq running experiment in machine translation related tasks:

AttributeError: module 'sacrebleu' has no attribute 'compute_bleu'

After consulting, it is a problem with sacrableu version 2.0. Only the following operations are required:

pip uninstall sacrebleu
pip install sacrebleu==1.5.1

Problem solved!

c# Newtonsoft.Json.JsonReaderException: ‘Error reading JArray from JsonReader. Path ‘‘, line 0

When the data queried by c# datatable is converted to JSON object, the following error is reported.

Newtonsoft.Json.JsonReaderException: 'Error reading JArray from JsonReader. Path '', line 0, position 0.

The reason for this problem is that the queried data set directly becomes a string, and then an error is reported when it is empty
solution: add judgment

		if (jsonStr.Length > 0)
                {
                    JArray jArray = JArray.Parse(jsonStr);
                    JProperty Data = new JProperty("Data", jArray);
                    ZzjDataObj.Add(Data);
                }

Error querying database.Cause:java.sql.SQLSyntaxErrorException:ORA-00911:invalid character

This problem is well positioned. At first glance, it is the problem of parameter transmission. Through this error report, the first thing to consider is the like part of the query condition.

The main idea of this problem is 1. Special characters are passed, such as’ ‘

2. See if the like query uses #{} or ${}

3. Is there a problem with where involving parameter statements
