If this error occurs, you need to re install the node_ Contents in the modules folder But before installing, you should clear all the previous contents. The steps are as follows:
1. Delete the node first_ modules
rmdir /s/q node_modules
2.delete package-lock.json file
3.npm cache clean –force
4.npm install（npm i is ok）
Comment out the three lines of code to solve the problem
Because of the NPM version problem, you can refer to the following two methods to solve. However, we must pay attention to which polyfills.js has a problem, which is explained in detail in the error prompt.
When I created a new Vue project today, I made a mistake like the title, which was disgusting at that time
Try the method of online God
Find the content to be modified by C:: (users/owner). Vuerc “ Usetaobaoregistry “: false, if the value is true or false, it is not easy to use
Then a whim called CMD as administrator to recreate the project successfully
For reference only, by the way, ask if there is a big God how to solve this problem: how to make the CMD run smoothly under the permission of non administrator?
After node.js is installed, use the instruction node version in vscode to show that it is not an external or internal instruction. The solution is as follows:
**
Method 1: restart vscode, and then re-enter node — version (1) find the code.exe file (2) right click the properties (3) after opening the compatibility, select to run the program as an administrator and click OK (4) in the last step, restart vscode and re-enter node — version
Vue import path ××× from ‘ ×××’ Error the file name and address introduced are correct, but the error is still reported already included file name‘ ×××’ differs from file name ‘ ×××’ only in casing.
At this time, we just need to remove the suffix Vue of the file name solution
Solution 1: remove the suffix Vue of the file name
Solution 2: change the point in front of the path to@
Path
function
./
current file sibling directory
./
current file superior directory
@
when importing a module, you can use @ instead of/SRC directory to refer to the relative path
Today, when I wrote node.js to operate the database, I encountered a typeerror: connection.connect is not a function when setting up the database connection. The following is the bug prompt, as shown in the figure when I found this error, I immediately went to connection.connect, but I didn’t find anything wrong, For this reason, I made a special effort to find the previous code and compare it. The following is the thinking at that time later, I asked my friend to check the custom module PS: after staring at it for more than ten minutes, I didn’t find the error. At this moment, I felt like a mentally retarded person later, I had to check one by one, I found that my mistake was to write the return value of the function as an object….. Verification complete….. Retarded stone hammer…..
Today, when I was crazy about writing code, I got the error of cannot find module ‘xxx’. Moreover, all the dependencies had been installed before, so I used the following code to install them all again, and then it was OK:
##Using webpack to report typeerror: this.getresolve is not a function
###Error reason: the webpack version is too low or the loader version is too high this is the original configuration version
##Solutions: 1. Upgrade the version of webpack to the highest version (there are many changes in the version of webpack, so I’m afraid it won’t catch up with others, So you can choose not to change the webpack version) 2. Reduce the version of the loader (1) manually reduce the downloaded version of the loader in package.json (2) download the loader you just used again and then run it again
Flash page is mounted at 127.0.0.1:8010 Vue page is mounted at 127.0.0.1:8080 (Axios. Defaults. Baseurl)=‘ http://127.0.0.1 :8010’）
After running, you can access port 8010, but when you access port 8080, you will be prompted with network error, and the security group port will be set to after checking, it is found that port 8010 is forward to port 1527 guess that port 8010 is occupied after a look, it is really so you can directly modify the page port in app.py to 5000, axios.defaults.baseURL = ‘ http://127.0.0.1 : 5000 ‘(or other non conflicting ports)
This time, you can directly access port 8080 it is found that using ‘127.0.0.1’ can still achieve public network page projection, but only using ‘0.0.0.0’ for flash
