关于UNI-APP小程序常见的问题汇总

1：报错：

10:14:28.022  ERROR  Error loading vue.config.js:
10:14:28.027  ERROR  Error: Cannot find module 'uni-read-pages'

运行：

 Npm install uni-read-pages --save-dev --legacy-peer-deps

2：报错

DEPRECATION WARNING: Using / for division is deprecated and will be removed in Dart Sass 2.0.0.

或

Vue2 scss 预编译器默认已由 node-sass 更换为 dart-sass，如果您的代码使用了 dart-sass 不支持的旧语法，可能存在部分不兼容的问题。

在manifest.json源码中添加一下代码，

"sassImplementationName": "node-sass"

示例：

"description" : "",  
"versionName" : "1.0.0",  
"versionCode" : "100", 
"transformPx" : false, 
"sassImplementationName": "node-sass",

3：跨域问题

报错：Access to XMLHttpRequest at 'https://ow3c72uxp6.by.takin.cc/zyj-api-web/hzsx/aliPay/index/getIndexActionListByPage?pageNum=1&pageSize=10&channelId=H01' from origin 'https://192.168.100.137:5054' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

跨域问题

1：检查前端跨域配置，正常如下。

traget：本地接口地址

 "devServer" : {
            "port" : 5054,
            "proxy" : {
                "/zyj-api-web" : {
                    "target" : "https://ow3c72uxp6.by.takin.cc/zyj-api-web/", //你的接口地址
                    "changeOrigin" : true,
                    "ws" : true,
                    "pathRewrite" : {
                        "^/zyj-api-web" : ""
                    }
                }
            },
            "https" : true
        }

2：检查前端baseUrl

baseurl正常情况只写：/zyj-api-web 就OK了

4：报错
