在 GitHub 上面找了几个项目,下载下来想执行以下,首先根据 README 文档进行安装依赖:
npm install
但接下来就一直报错,报错信息如下:

搜寻了好多种解决方法,依然不行,最后看到一篇博客说是C盘 User 文件夹中的.npmrc 文件的问题,于是我尝试删除该文件,再次进行npm install ,此时报错信息开始发生变化:

根据报错信息提示,可能是需要将 npm 版本从8.19.2 升到9.6.3,于是我继续执行npm install -g npm@9.6.3
而此时终于没有报错了,证明 npm install 成功了。
PS G:\前端自学资料\项目实例\Vue 项目\vue2-douban-market-master> npm install -g npm@9.6.3added 1 package, and audited 238 packages in 8s18 packages are looking for fundingrun `npm fund` for detailsfound 0 vulnerabilitiesPS G:\前端自学资料\项目实例\Vue 项目\vue2-douban-market-master>
以上我以为解决了 npm install 一直报错的问题,但接下来,根据 README 文档要求,运行项目时又出现另一个问题:
PS G:\前端自学资料\项目实例\Vue 项目\vue2-douban-market-master> npm run dev>>> node build/dev-server.jsnode:internal/modules/cjs/loader:998throw err;^Error: Cannot find module 'chalk'Require stack:- G:\前端自学资料\项目实例\Vue 项目\vue2-douban-market-master\build\check-versions.js- G:\前端自学资料\项目实例\Vue 项目\vue2-douban-market-master\build\dev-server.jsat Module._resolveFilename (node:internal/modules/cjs/loader:995:15)at Module._load (node:internal/modules/cjs/loader:841:27)at Module.require (node:internal/modules/cjs/loader:1061:19)at require (node:internal/modules/cjs/helpers:103:18)at Object.

根据报错信息,它要求安装 ‘ chalk ‘,但我 npm install chalk ,又会报错,报错信息和第一次一样,说到底,依赖就是没安装成功。有人说是node-sass 的问题:
它是一个 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,而我安装的 node 版本是18.12.1 ,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。
但我电脑上明明安装了visual studio 2019 ,不知道为什么还是报错,根据我找到这个博主的解决方案:http://t.csdn.cn/TwEll
用两种方法处理依赖:
方式一、替换依赖
卸载旧版本的 node-sass 和 sass-loader,安装 sass 和 sass-loader,不再使用 node-sass
// 第一步:npm uninstall sass-loader node-sass// 第二步:npm install sass-loader@8.0.2 sass@1.26.5 -D
方式二、安装指定版本依赖
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
但我尝试之后,又报出下面的错误
npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!

新的问题又产生,没办法,再找解决方法:
根据其报错提示,我们去执行 npm install –force 或者 npm install–legacy-peer-deps,
但。。。。。。好像一进行 npm install ,马上又回到最初的那个报错,死循环了,没有找到关键问题,归根结底还是依赖没能安装成功的缘故。最后,我又去翻看了一下README 文档,发现该项目是在 nodejs 6.10.0 下开发的:
而我使用的是 nodejs 18.12.1 版本,初步判断就是由于我使用的版本太新,超出这个项目所需的要求,使得 npm 的包出现问题,一直报错,而这里,我又看到 README 文档 说建议使用 yarn 下载依赖,我果断尝试,最后完美解决了项目下载依赖并运行会报错等系列问题。【所以说还是得注意 README 文档的相关信息】
至于怎么解决 npm 包的问题导致无法加载依赖和运行项目 npm run dev 会报错的问题,暂时认为需要换成对应的 node.js 版本,但频繁换 node.js 版本也很不方便,这时可以使用nvm,一个nodejs 版本管理工具!来进行版本是使用控制。
下面说说下载安装 nvm 的步骤:
【写在前面】首先要注意,先把电脑上的 nodejs 卸载干净,否则后面会出现一些问题。
1. 去官网下载并安装:https://nvm.uihtm.com/
【注意】选择 nvm 安装路径时文件夹名不要出现中文和空格
2. 以管理员身份运行并输入 nvm ,出现下图信息说明安装成功
3.nvm 命令
常见的 nvm 命令
1. nvm -v //查看 nvm 版本
- nvm -version // 显示nvm 版本及其信息
2.nvm list //显示版本列表
- nvm list :显示已安装的版本(同 nvm list installed
- nvm list installed:显示已安装的版本
- nvm list available:显示所有可以下载的版本
3. nvm install //安装指定版本node.js
- nvm install 16.5.0:安装 16.5.0 版本的 node.js
- nvm install latest:安装最新版本
4. nvm use // 使用指定版本node
- nvm use 16.5.0: 切换到 16.5.0 版本的 node.js
- –lts // 自动切换到长期支持版本
- –lts= // 自动切换到指定名称的 node 长期支持版本
5. nvm uninstall // 卸载指定版本 node
- nvm uninstall 14.5.0:卸载到 14.5.0 版本的 node.js
- nvm uninstall –lts // 卸载长期支持版本的node
- nvm uninstall –lts= // 卸载一个指定名称的长期支持版本的node
6. nvm –help//显示命令行帮助信息
【注】在运行 nvm install 的时候,有可能会出现无权限安装的问题,请以管理员身份运行cmd
其他的命令
- nvm deactivate // 取消当前nvm命令行效果
1. nvm 查看 node 版本
- nvm current // 查看当前使用的 node 版本
- nvm ls // 查看所有本地可用的 node 版本
- nvm ls // 参看指定版本
- nvm ls-remote // 查看所有可用远程版本
- –lts // 查看所有长期支持版本
- nvm ls-remote // 参看所有 node 的指定远程版本
- –lts // 查看所有 node 长期支持版本
- –lts= // 仅查看指定名称的长期支持版本
2. nvm 版本别名
- nvm alias [] // 显示所有以 开头的版本别名
- nvm alias // 给版本 设置一个别名
- nvm unalias // 删除 的版本别名
3. nvm 和 npm
- nvminstall-latest-npm // 在当前 node 版本中,将 npm 升级到最新版
- nvmreinstall-packages // 在全局重新安装 npm,从 版本到当前版本
4. npm which 显示安装路径
npmwhich[current | ] // 显示已安装 node的安装路径。
5. nvm缓存
- nvmcachedir // 显示 nvm 的缓存目录
- nvmcacheclear // 清除nvm 的缓存目录
6. nvm 运行 node
- nvm exec [–silent] [version] [] // 在 运行命令
- nvm exec 4.8.3 node app.js // Run `node app.js` with the PATH pointing to node 4.8.3
- nvm run [–silent] [version] [] // 在以参数运行node —
- nvm run 6.10.3 app.js //Run app.js using node 6.10.3
7. 设置镜像
- nvm node_mirror [url] :设置 node 镜像。默认是 https://nodejs.org/dist/。如果不写 url,则使用默认 url。设置后可至安装目录 settings.txt 文件查看,也可直接在该文件操作。
- nvm npm_mirror [url] :设置 npm 镜像。https://github.com/npm/cli/archive/。如果不写 url,则使用默认 url。设置后可至安装目录 settings.txt 文件查看,也可直接在该文件操作。
8. 版本管理
nvm on
:开启 node.js 版本管理。nvm off
:关闭 node.js 版本管理。
