周五按照网上教程进行按照，报错再百度搜索找方案。之前一直在vue-devtools文件夹中使用git bash进行cnpm install安装不成功，报各种依赖包不支持。报错类似如下：

npm WARN .. requires a peer of react@^16.4.0 but none is installed

报错内容过多，需要安装依赖包太多。然后将npm版本号降到6.0.1，报错更多。类似

npm WARN npm npm does not support Node.js v14.16.0 npm WARN npm You should p

然后卸载node。再进行安装还是如此。周一上班开机后继续折腾，结果可行。记录步骤如下：

1、在vue-devtools目录下git bash 执行安装命令 $ cnpm install

报错error：

可能cnpm未安装

2、执行 $ npm install

报错error：

3、使用 win+R打开cmd 执行命令 npm install

报错error：有警告有报错

4、继续执行 npm install cnpm -g --registry=https://registry.npm.taobao.org （ 安装淘宝镜像 ）

报错error：

npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated uuid@3.4.0: Please upgrade  to version 7 or higher.  Older versions may use Math.random() in certain circumstances, which is known to be problematic.  See https://v8.dev/blog/math-random for details.

removed 384 packages, and changed 378 packages in 2m

3 packages are looking for funding
run `npm fund` for details

百度搜索：

提示内容，部分内容不再维护，可以继续安装，影响不大

5、执行 npm config set registry https://registry.npm.taobao.org （ 设置源 ）无反应，然后执行

npm start

报错error：

npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path C:\Users\linger/package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'C:\Users\linger\package.json'

5、继续执行 npm install nrm -g （ npm升级到最新版本 ） 有报错但是也正常安装

npm WARN deprecated har-validator@5.1.5: this library is no longer supported
npm WARN deprecated request@2.88.2: request has been deprecated, see https://github.com/request/request/issues/3142

added 61 packages in 1m

1 package is looking for funding
run `npm fund` for details

6、执行 cnpm -v ( 查看版本 ) 查看是否安装成功。

cnpm@7.1.0 (C:\Users\linger\AppData\Roaming\npm\node_modules\cnpm\lib\parse_argv.js)
npm@6.14.15 (C:\Users\linger\AppData\Roaming\npm\node_modules\cnpm\node_modules\npm\lib\npm.js)
node@16.13.1 (D:\Program Files\node.exe)
npminstall@5.3.1 (C:\Users\linger\AppData\Roaming\npm\node_modules\cnpm\node_modules\npminstall\lib\index.js)
prefix=C:\Users\linger\AppData\Roaming\npm
win32 x64 10.0.19042
registry=https://registry.npmmirror.com

安装成功，可以看到版本号和安装地址 都在c盘下。

7、回到git命令行界面，执行命令 $ cnpm install （安装依赖）正常执行

链接748最新版本

。。。中间一些警告内容。。。

已安装所有软件包（从npm注册表安装920个软件包，使用3m（网络3m），速度177.27KB/s，json 749（3.42MB），tarball 23.26MB）

8、查找目录 vue-devtools\packages\shell-chrome 下的

可能是新版本，，跟网络上的其他文章地址不一致。

老版本地址：vue-devtools\shells\chrome

新版本地址如下：

9、打开找着"persistent": false 将值修改为 true

10、保存编译 执行命令 $ npm run build （ 编译 ）

> vue-devtools@6.0.0-beta.20 build
> lerna run build

lerna notice cli v4.0.0
lerna info Executing command in 9 packages: "yarn run build"
lerna ERR! yarn run build exited 1 in '@vue/devtools-api'
lerna ERR! yarn run build stderr:

���������ļ���
lerna ERR! yarn run build exited 1 in '@vue/devtools-api'

有报错 ，放置不理，安装时会报错

所以仍然需要安装yarn

11、执行 $ npm install yarn -g ( 安装 yarn 工具 )

12、执行 $ yarn install ( 用 yarn 安装依赖 )

......

13、执行 $ yarn run build （ 用 yarn 编译 ）

yarn run v1.22.17
$ lerna run build

还是有报错

原因可能为node安装包有遗漏模块没有安装，也可能是 路径不对有中文。重新下载安装node后发现问题并未解决。返回上一步，查看错误信息。

warning " > webpack-dev-server@4.0.0-rc.0" has unmet peer dependency "webpack@^4.0.0 || ^5.0.0".

（Webpack-dev-server 有未满足的对等依赖）
怀疑没有安装webpack。
（注意：如果安装完webpack还依然报 has unmet peer dependency xxx，则尝试关闭git命令窗口再打开git命令窗口，在新窗口中执行命令）
 
14、再次执行  $ cnpm install 返回正常。

16、关闭git命令行窗口，还是在vue-devtools文件夹打开新git bash 命令行窗口，执行
 
yarn install （安装依赖）
 
17、 执行 $ yarn run build （编译）
 
18、 添加扩展程序
 
Chrome浏览器右上角竖向排列3点 》更多工具 》 扩展程序 ，点击
 
打开vue-devtools目录下的shell-chrome，点击选择文件夹。 
 
 安装成功！
 
19、设置，点击地址栏右侧拼图图标 》扩展程序 》 Vue.js devtools 右侧的图钉点上。适中固定展示。
 
 20、测试 （B站有使用vue开发，打开首页）右侧展示成功。若页面没有使用vue，则展示为灰色

                                    删除npm的缓存 （即删除文件夹C:\Users\Administrator\AppData\Roaming\npm-cache下的内容）#  赋予该文件夹的访问权限（安装过程若对此有提示，则加入）： C:\Users\Administrator\AppData\Local\tmp。#  赋予该文件夹的访问权限： C:\Users\Administrator\AppData\Roaming\npm。npm首先会在你的项目文件夹下创建本机的“临时的稳定版的的分析存储库”文件夹：.staging。
原因：主要是单个包的安装出现错误
解决：使用 --ignore-scripts 安装 ，先把某个报错的包单独安装，eg:npm i cypress@3.8.3 --ignore-scripts
npm run build中出现：Failed at the vue-devtools@6.0.0-beta.15 build script.
