一、问题描述

首先正常 yarn add .,发现依赖中node-sass无法正常安装导致编译中断,于是单独安装node-sass,报错如下

这种情况我们一般都只会说依赖出现问题了。按常规的方法,删除依赖,重新安装

而对出现报错的归因解释得通俗易懂的,可以参考——思否-npm i 运行错误 这个解答

是 node-sass 的问题,这是一个 native 包,默认情况下每个 node 版本都需要单独的 node-sass,一般会从 github release 上下载,你的node版本是 v16.xx.xx ,github release 没有这个版本,所以会转向本地构建,本地构建需要 windows build tools,简单说就是需要安装 visual studio 2019。安装这个后你的环境变量里就可以使用 python 等命令,但是明显你没有,所以会报错

所以针对这个问题,有两种解决思路

二、解决方案

(一)、node降级(不推荐)

node切换为v12或者v14的版本

(二)、处理依赖

对依赖的处理方式也有两种方式

参考 CSDN-node16 node-sass 版本

方式一、替换依赖

卸载旧版本的node-sasssass-loader,安装sasssass-loader,不再使用node-sass

1

2

npm uninstall sass-loader node-sass

npm install sass-loader@8.0.2 sass@1.26.5 -D

方式二、安装指定版本依赖

安装node16+相对应版本的node-sasssass-loader

1

npm i node-sass@6.0.1 sass-loader@10.2.0

如果使用方法二之后报错,可能是安装过程中某些包丢失,尝试以下方法解决:

1

npm rebuild node-sass

## 根据自己使用的nodejs版本情况,选择node-sass和sass-loader对应的版本。

>node 12.x-14.x版本对应如下sass版本:

node-sass@4.14.1 (全局安装使用,不用安装到项目):npm install node-sass@4.14.1 -g

sass-loader@8.0.2 (全局安装使用,不用安装到项目):npm install sass-loader@8.0.2 -g

dart-sass@1.25.0 (项目中):npm intsall dart-sass@1.25.0

>node 16.x版本对应如下sass版本:

node-sass@6.0.1 (全局安装使用,不用安装到项目):npm install node-sass@6.0.1 -g

sass-loader@10.2.1 (全局安装使用,不用安装到项目):npm install sass-loader@10.2.1 -g

dart-sass@1.25.0 (项目中):npm intsall dart-sass@1.25.0

解决了Cannot read properties of undefined (reading ‘parseComponent‘)

Vue中eslint报错的修改,绝对有效!!!

Syntax Error: TypeError: Cannot read properties of undefined (reading 'parseComponent')

You may use special comments to disable some warnings.

Use // eslint-disable-next-line to ignore the next line.

Use /* eslint-disable */ to ignore all warnings in a file.

方法一:

1.找到文件 .eslintrc.js文件,如下图,把 '@vue/standard’注释掉

方法二:

1.找到文件 vue.config.js

修改lintOnSave 为false,如果没有就添加vue.config.js这个文件并把 lintOnSave 设置为false

方法三:

就是所谓的在build/webpack.base.conf.js文件中,注释或者删除掉:module->rules中有关eslint的规则,(我有这个文件但是内容空空白白,然并软,这张图复制别人的,位置就是那里)

方法四:

以上三种方式都无效的我,浪费一下午找的,最后差点信了有些人的鬼话想去卸载脚手架vue-cli,我真是服了那些出馊主意的人,最后这个方式解决了,

1、 yarn add vue-template-compiler

或 npm add vue-template-compiler

2、最后如果还是不行就再用

yarn upgrade –latest vue-template-compiler

npm upgrade –latest vue-template-compiler

最近多次遇到这个问题,node16+版本安装或者初始化带有node-sass和sass-loader包的项目报错。翻遍了所有相关文章,总结出以下两种解决办法:

方法一:

卸载旧版本的node-sass和sass-loader,安装sass和sass-loader,不再使用node-sass

npm uninstall sass-loader node-sass

npm install sass-loader@8.0.2 sass@1.26.5 -D

方法二:

安装node16+相对应版本的node-sass和sass-loader

npm i node-sass@6.0.1 sass-loader@10.2.0

如果使用方法二之后报错,可能是安装过程中某些包丢失,尝试以下方法解决:

npm rebuild node-sass
