According to the project construction and related environment configuration

Recently, the software engineering class is coming to an end, and the big homework is to do a document management system, so I picked up Ruoyi again, and I was going to do it briefly. It turned out that there was a problem with the previous node environment, so I simply reinstalled and configured one.

Node, js download and environment configuration

1. First download and install the
   official website: link: link
   The current version is more than 18, but I do not recommend using the new version, there will be many bugs, I have encountered it during installation, the modification method provided does not work, simply delete it , version 16 installed.
2. The installation path of my node.js is **E:\Program Files\nodejs
   First create two folders under the installation directory, named node_cache, and node_global.
   
   Open the command line window in nodejs, and enter the command:

// npm config set prefix "E:\Program Files\nodejs\node_global"
//npm config set cache "E:\Program Files\nodejs\node_cache"

Open the environment variable window to set
what is an environment variable and why should it be configured? Here's another blog post:

   and save it.
   Enter node -v and npm -v respectively to view the version number

If you need to use Redis in the separate version, I used version 3.2 because I had it before.

1. Ruoyi official website: link: link
   I downloaded the front-end and back-end separation version
   
   After decompression:
   
   I use IDEA for the compiler, drag the RuoYi-Vue-master folder to IDEA to open it.
2. After opening with IDEA, you need to configure the database. I use MySQL, open the application-druid.yml configuration file, and
   
   modify the database name and password:
   
3. Start the backend: Run RuoYiApplication
   
   to start successfully:
   
4. Start the front end:
   You can also directly enter the npm run dev command in the ruoyi-ui folder.

The startup is successful:
if there is a 500 error, there is a problem with the database connection. I have encountered:

1. MySQL service is not started
2. There is an error in the application-druid.yml configuration file

If you come here, it will start successfully.
