Cannot read property ‘isFile‘ of undefined [How to Solve]

Today, when I started the project, I couldn’t get up. I always reported an error. After translation research, I came to the solution

When executing Vue project NPM run dev FileManager webpack plugin error typeerror: cannot read property 'isfile' of undefined 

D:\abinwork\fmis_web\node_modules\filemanager-webpack-plugin\lib\index.js:271
        if (isGlob) archive.glob(command.source, globOptions);else if (sStats.isFile()) archive.file(command.source, { 
        name: path$1.basename(command.source) });else if (sStats.isDirectory()) archive.glob('**/*', {
                                                                              ^

TypeError: Cannot read property 'isFile' of undefined
    at D:\abinwork\fmis_web\node_modules\filemanager-webpack-plugin\lib\index.js:271:79
    at D:\abinwork\fmis_web\node_modules\graceful-fs\polyfills.js:282:31

The reason for the error is very simple, because the project we just pulled down does not have a dist directory, and then FileManager webpack plugin find a dist directory and find that it does not exist, and then strike and quit, resulting in an error;

There are two solutions

First, you can repackage it;

npm run build

Second, modify the configuration and automatically create the dist directory when running

Note: look at the first step first. If you can run the NPM run build and then the NPM run dev project, you don’t have to perform the second step

plugins: [
    new FileManagerWebpackPlugin ({
      onEnd: {
        mkdir: [‘./dist‘],
        delete: [
          ‘./dist.zip‘,
        ],
        archive: [
          {source: ‘./dist‘, destination: ‘./dist.zip‘},
        ]
      }
    })
  ],

Antdesignvue autocomplet completes the problem of repeated error reporting

If the data IDs are different, and there are multiple identical name values or multiple identical Title values, an error will be reported
just do it

    <a-auto-complete
      v-model="ruleForm.companyId"
        placeholder="Please Input"
        optionLabelProp="label"
        @select="onSelect"
        @change="onChangeStore"
      >
        <template slot="dataSource">
          <a-select-option
            v-for="item in dataSource"
            :key="item.id"
            :value="item.id + ''"
            :label="item.name"
          >
            {{ item.name }}
          </a-select-option>
        </template>
    </a-auto-complete>

Vue project reports an error on ie11 white screen. Script1002: syntax error

Problem phenomenon

The project is a front-end project built with Vue/cli3 scaffold, and Vue version is 2.6.10.

Ie11 error reporting problems are as follows:

  (there was no screenshot in the error report at that time, but someone else’s picture was used)

 

It’s annoying that there’s no way to check mistakes like this

Baidu a pile, all copy to copy, the key has not been able to solve the problem, shit! Omnipotent Google up

  In fact, this problem is obviously a syntax error, that is, the problem that ie does not support, ie garbage

Since it’s a syntax problem, it’s a compilation problem. Let’s directly compile the corresponding package, but which package is it

Here’s the point: when you click the error message, you will find that the place where the breakpoint is is the place where the error is reported. That must be the problem here, but this is the compiled code. How to check which package is a headache!

When I was having a headache, I found that the comment above was the name of the package???

It’s like discovering a new world

It’s him. This picture is not my error information. My error information is

./node_modules/[email protected]@js-base64.js

Since the package with the problem is found, specify that it be compiled; Using webpack

Directly configure the compiled code in vue.config.js

transpileDependencies: [
    /[/\\]node_modules[/\\][email protected]@js-base64[/\\]/,
 ],

Then directly NPM run serve

be accomplished! It’s done! go off work!

Error “NPM err” when starting Vue project! code ELIFECYCLE”

Since NPM and cnpm have been used together before, there is no problem. Today, when starting the Vue project, I encountered an error “NPM”   ERR!   code   “Elifecycle” was initially used with NPM   Run started and later changed to cnpm   Neither can run.

  After checking the information, it is mostly said on the Internet that it is because of node_ There is a problem with the installation of modules. The basic solution is to clear the cache and reinstall.

The following steps are summarized:

1、npm   cache   clean  — force

2、rm  – rf   node_ modules

3、rm  – rf   Package-lock.json (optional)

4、npm   install

 

 

Error in legal external terminal in ANSYS electronics desktop

report errors     Illegal external terminal ‘CoilTerminal1’: An external terminal must border the edge of the problem region and coincides with the surface of a 3D object

Solution: the surface of the excitation port you set (that is, where the current flows in and out) should coincide with the vacuum package you set (that is, the surface of the region).

Vue packages version mismatch

Failed to compile.

./src/App.vue
Module Error (from ./node_modules/vue-loader/lib/index.js):


Vue packages version mismatch:

- [email protected] (D:\site\hst_tech\hst_platform_frontend\node_modules\vue\dist\vue.runtime.common.js)
- [email protected] (D:\site\hst_tech\hst_platform_frontend\node_modules\vue-template-compiler\package.json)

This may cause things to work incorrectly. Make sure to use the same version for both.
If you are using vue-loader@>=10.0, simply update vue-template-compiler.
If you are using vue-loader@<10.0 or vueify, re-installing vue-loader/vueify should bump vue-template-compiler to the latest.

Solution:

Set Vue template- [email protected] Version change Vue template- [email protected]

// Just change the version number to the same one
npm i -g [email protected] --save

[Solved] Project Package Error: Javascript heap out of memory

Project package error:JavaScript heap out of memory
1、Modify package.json add –max_old_space_size=8192

"pro": "cross-env NODE_ENV=production node --max_old_space_size=8192 ./dist/server/server.js",

2. Execute increase memory limit


// global install
npm i -g increase-memory-limit

// into the project
increase-memory-limit

Error JavaScript heap out of memory means that the JavaScript heap is out of memory. JavaScript here refers to node. We all know that node is based on V8 engine. In general back-end development languages, there are no restrictions on the use of basic memory. However, when using memory through JavaScript in node, only part of the memory can be used (about 1.4 GB in 64 bit system and about 0.7 GB in 32-bit system). If the front-end project is too large, webpack compilation will occupy a lot of system resources. When it exceeds the default memory limit of V8 for node, memory leakage will occur.
