Summary of error reports when starting the uniapp cli-based one-click travel project

Question 1. Use hbuilder to run the command, but nothing happens after starting the compilation. Use the command build to end the process by itself.

Solution: Because node16.24 is used, after uninstalling and reinstalling 14.17, multiple versions are used.

The tutorial is as follows

Windows: Use nvm to install multiple versions of node.js_Tips: now using node v16.14.2 (64-bit)-CSDN Blog

Change the configuration of vue.config.js as follows

module.exports = {
    /* css配置 */
    css: {
        loaderOptions: {
            /* 全局引用 scss 文件 */
            sass: {
                additionalData: `@import "@/assets/css/mixin.scss";`
            },
        },
    },
}

Change to additionalData ==》prependData

module.exports = {
    /* css配置 */
    css: {
        loaderOptions: {
            /* 全局引用 scss 文件 */
            sass: {
                prependData: `@import "@/assets/css/mixin.scss";`
            },
        },
    },
}

Solution, the node version is too high

"node-sass": "^4.14.1",
"sass-loader": "^8.0.2",

Question 3.

gyp find PythonERR! find Python Python is not set from command line or npm 

solution

npm install --global --production windows-build-tools

Question 4.

Syntax Error: Error: Node Sass version 6.0.1 is incompatible with ^4.0.0.

 Solution, the node version is too high

"node-sass": "^4.14.1",
"sass-loader": "^8.0.2",

The most important step is to delete the package-lock.json file and re-download the dependent packages.

Then, remove the dependent folders in the specified directory

rimraf node_modules

Next, force clear the npm cache

npm cache clean --force

at last,

# It is strongly recommended not to use cnpm to install directly. There will be various weird bugs. You can solve the problem of slow npm installation speed by re-specifying the registry.

npm install --registry=https://registry.npmmirror.com
