解决方案1

除 yarn.lock 文件，重新执行

yarn install

7. yarn install 遇到报错：error commander@11.1.0: The engine “node” is incompatible with this module. Expected version “>=16”. Got “14.16.1” error Found incompatible module. info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

解决方案1
 yarn config set ignore-engines true

删除之前node-mdules ,重新执行

yarn install


8. 报错This dependency was not found,To install it, you can run: npm install --save vxe-table/lib/vxe-table

This dependency was not found:
- vxe-table/lib/vxe-table in ./src/plugins/vxetable.ts
To install it, you can run: npm install --save vxe-table/lib/vxe-table
解决方案：

查访此issue后得知:

  • 把package.json里babel-plugin-import版本前的 ^ 符号删掉
  • 删除node-modules包
  • 删除lock文件
  • 重新下载依赖

9. npm ERR! Maximum call stack size exceeded报错

解决方案如下：

1.更新npm版本

// 查看版本
npm -v
// 更新
npm install -g npm

2.删除node_module和package-lock.json

3.重新执行npm install

4.如果还不行，执行下面命令

npm cache clean --force

5.继续执行npm install

6.完美解决问题~~~~~

10. mac 配置yarn 环境，command not found: yarn，解决无法npm -g的情况遇到问题：zsh: command not found: yarn

解决方案

前提：电脑已安装node

node -v

全局安装

npm install yarn -g

如果这一步没有问题，就不需要往下看了,可以直接执行 yarn 命令了

11.mac 配置yarn 环境,如果遇到报错The operation was rejected by your operating system.npm ERR! It is likely you do not have the permissions to access this file as the current user

XXXX@CN_C02GXXX6M ~ % npm i yarn -g
npm ERR! code EACCES
npm ERR! syscall rename
npm ERR! path /usr/local/lib/node_modules/yarn
npm ERR! dest /usr/local/lib/node_modules/.yarn-Jrexx8nI
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, rename '/usr/local/lib/node_modules/yarn' -> '/usr/local/lib/node_modules/.yarn-Jrexx8nI'
npm ERR!  [Error: EACCES: permission denied, rename '/usr/local/lib/node_modules/yarn' -> '/usr/local/lib/node_modules/.yarn-Jrexx8nI'] {
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'rename',
npm ERR!   path: '/usr/local/lib/node_modules/yarn',
npm ERR!   dest: '/usr/local/lib/node_modules/.yarn-Jrexx8nI'
npm ERR! }
npm ERR! 
npm ERR! The operation was rejected by your operating system.
npm ERR! It is likely you do not have the permissions to access this file as the current user
npm ERR! 
npm ERR! If you believe this might be a permissions issue, please double-check the
npm ERR! permissions of the file and its containing directories, or try running
npm ERR! the command again as root/Administrator.

解决报错方案一：

sudo npm i yarn -g

解决报错方案二：（仅限电脑权限管控严格情况下，无法获取权限）

step1: 查看npm 全局文件安装地址
XXX@CN_CXXXMD6M ~ % npm list -g                    
/usr/local/lib
├── @quasar/cli@1.3.2
├── corepack@0.14.1
├── npm@8.19.2
└── yarn@1.22.18
step2: 从其他人电脑上同样的目录，拷贝出来两份文件，一个是命令的快捷方式文件，一个是环境变量所指的路径文件，粘贴到自己电脑相同位置

  • 命令快照文件


  • 全局命令所指文件

step3: 打开环境变量配置文件，配置环境变量
vim ~/.bash_profile

把下面内容粘贴到环境变量文件里，

export PATH=/usr/local/lib/node_modules/yarn/bin/:$PATH

保存.bash_profile的编辑，执行一下文件

source ~/.bash_profile

问题解决，大功告成

命令行重新打开，就可以使用yarn

yarn -v

12. MAC npm install -g 报错permission denied

参考我的这篇文章：超详细手把手教你四种方案彻底解决MAC npm install -g 报错permission denied

13. npm 启动项目报错 Cannot find module ‘@babel\compat-data\data\corejs3-shipped-proposals’

最近升级了系统的node ,webpack 等等，然后今天打开项目，突然启动不起来了~~
报错信息如下：
Module build failed (from ./node_modules/babel-loader/lib/index.js):
Error: Cannot find module 'D:\\trunk\node_modules\@babel\compat-data\data\corejs3-shipped-proposals'
搜索了一下资料，按照解决方案来尝试
方案一：（尝试过后对我的项目没有用）
package.json中devDependencies对象添加
  "@babel/compat-data": "7.9.0"
方案二：执行下面命令，然后再重新启动
npm install -D babel-loader @babel/core @babel/preset-env webpack

14. mac npm install -g后仍然不行怎么办sudo: xxx: command not found

参考我这篇文章：多种方案教你彻底解决mac npm install -g后仍然不行怎么办sudo: xxx: command not found

15. 解决npm install各种报错的6种方案 Error: Command failed: cmd.exe autoreconf -ivf以及gifsicle pre-build test failed

参考我这篇文章：解决npm install各种报错的6种方案 Error: Command failed: cmd.exe autoreconf -ivf以及gifsicle pre-build test failed以及其他报错

16. nodejs 升级后， vue+webpack 项目 node-sass 报错的解决方法

如果按照此步骤执行有问题，请参考18 解决安装node-sass报错的方法

1.当我执行npm i node-sass -D 在错误提示里有给出了方案，重新构建 node-sass，命令如下：
npm rebuild node-sass --force

如果执行完成后不报错，就可以了。

如果报 gyp Error 错误：
gyp ERR! configure error 
gyp ERR! stack Error: `gyp` failed with exit code: 1
....
gyp ERR! node -v v8.11.1 
gyp ERR! node-gyp -v v3.6.2
卸载 node-sass，然后重新安装。
npm uninstall node-sass
npm install node-sass
rebuild
## 第一步：
npm rebuild node-sass
## 第二步：
npm update

如果按照此步骤执行有问题，请参考18 解决安装node-sass报错的方法

17. npm install报错 npm ERR! gyp verb which failed Error: not found

# install node-gyp globally
npm install -g node-gyp
解决方案2

在项目根目录下创建.npmrc

sass_binary_site=https://npm.taobao.org/mirrors/node-sass/

18. 解决安装node-sass报错的方法

方案1：使用淘宝镜像
npm set sass_binary_site http://cdn.npm.taobao.org/dist/node-sass
方:2：下载源码放到本地搞~~ 适合内网开发的苦孩子们~~~
  • 先进入https://github.com/sass/node-sass/releases下载自己需要的包
  • 可以点击tags然后找到自己需要的，然后进行下载
  • 举例：下载下面这个

https://github.com/sass/node-sass/releases/download/v4.13.1/win32-x64-79_binding.node

  • 下好后，放到本地的文件夹里，使路径如下
C://Users//AAAAAA//AppData//Roaming//npm-cache//node-sass//4.13.1//win32-x64-79_binding.node
  • 然后按顺序复制下面的代码到命令行
set SASS_BINARY_PATH="C://Users//AAAAAA//AppData//Roaming//npm-cache//node-sass//4.13.1//win32-x64-79_binding.node"
npm install node-sass@3.4.1

19. 待补充

  • 然后你会发现，安装成功了~~~~

  • 今天就写到这里啦~

  • 小伙伴们，(￣ω￣(￣ω￣〃 (￣ω￣〃)ゝ我们明天再见啦~~

  • 大家要天天开心哦
