node npm install引用安装依赖包更改为私有库地址

背景：项目使用了bpmn.js作为前端的流程引擎，但是需要更改配置文件和映射关系，或者直接修改源码，但是通过npm install安装的是默认的git 地址，于是就需要将bpmn.js拷贝一份到公司的私有库，然后前端引用的git的地址变为私有库的地址，好了

看效果

步骤如下

第一，建立自己的私有库（略过此步）

第二，将bpmn.js的代码上传到我们的私有库git的地址（此步略过）

第三，将项目引用的git的地址更改为私有库地址

1、看我们package.json中的配置

{
  "name": "bpmn",
  "version": "0.0.1",
  "description": "A process designerI",
  "keywords": [
    "bpmn",
    "bpmn.js",
    "vue"
  ],
  "repository": {
    ....
  },
  "scripts": {
    ...
  },
  "dependencies": {
    "bpmn-js-sketchy": "^0.5.3",
    "bpmn-js-task-resize": "^1.2.0",
    "bpmn-js-token-simulation": "^0.10.0",
    "core-js": "^3.8.1",
    "diagram-js-minimap": "^2.0.4",
    "highlight.js": "^10.5.0",
    "js-base64": "^3.7.2",
    "min-dash": "^3.5.2",
    "vue": "^2.6.11",
    "vue-router": "^3.4.9",
    "x2js": "^3.4.3",
    "xml-js": "^1.6.11"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "@vue/compiler-sfc": "^3.0.1",
    "@vue/eslint-config-prettier": "^5.0.0",
    "axios": "^0.21.1",
    "babel-eslint": "^10.1.0",
    "bpmn-js": "^8.8.3",
    "bpmn-js-properties-panel": "^0.37.2",
    "camunda-bpmn-moddle": "^4.4.1",
    "compression-webpack-plugin": "^6.1.1",
    "element-ui": "^2.13.2",
    "eslint": "^6.7.2",
    "eslint-plugin-prettier": "^3.1.0",
    "eslint-plugin-vue": "^6.2.2",
    "fs-extra": "^8.1.0",
    "sass": "^1.30.0",
    "sass-loader": "^8.0.2",
    "script-ext-html-webpack-plugin": "^2.1.5",
    "terser-webpack-plugin": "^4.2.3",
    "vue-template-compiler": "^2.6.11",
    "webpack-bundle-analyzer": "^3.9.0",
    "cross-env": "^7.0.3"
  },
  "eslintConfig": {
    ...
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not dead"
  ],
  "license": "Apache"
}

可以看到直接通过npm install的方式，默认是安装的是bpmn.js 8.8.3版本

所以，为了安全与稳定起见，我们项目也应该安装该版本的

于是，私有库建立该分支，命名为

Branch_v8.8.3

 同时，修改引用依赖

"bpmn-js": "git+http://xxxx/bpmn-js.git#Branch_v8.8.3",

具体如下 

{
  "name": "bpmn",
  "version": "0.0.1",
  "description": "A process designerI",
  "keywords": [
    "bpmn",
    "bpmn.js",
    "vue"
  ],
  "repository": {
    ....
  },
  "scripts": {
    ...
  },
  "dependencies": {
    "bpmn-js-sketchy": "^0.5.3",
    "bpmn-js-task-resize": "^1.2.0",
    "bpmn-js-token-simulation": "^0.10.0",
    "core-js": "^3.8.1",
    "diagram-js-minimap": "^2.0.4",
    "highlight.js": "^10.5.0",
    "js-base64": "^3.7.2",
    "min-dash": "^3.5.2",
    "vue": "^2.6.11",
    "vue-router": "^3.4.9",
    "x2js": "^3.4.3",
    "xml-js": "^1.6.11"
  },
  "devDependencies": {
    "@vue/cli-plugin-babel": "~4.5.0",
    "@vue/cli-plugin-eslint": "~4.5.0",
    "@vue/cli-service": "~4.5.0",
    "@vue/compiler-sfc": "^3.0.1",
    "@vue/eslint-config-prettier": "^5.0.0",
    "axios": "^0.21.1",
    "babel-eslint": "^10.1.0",
    "bpmn-js": "git+http://xxxx/bpmn-js.git#Branch_v8.8.3",
    "bpmn-js-properties-panel": "^0.37.2",
    "camunda-bpmn-moddle": "^4.4.1",
    "compression-webpack-plugin": "^6.1.1",
    "element-ui": "^2.13.2",
    "eslint": "^6.7.2",
    "eslint-plugin-prettier": "^3.1.0",
    "eslint-plugin-vue": "^6.2.2",
    "fs-extra": "^8.1.0",
    "sass": "^1.30.0",
    "sass-loader": "^8.0.2",
    "script-ext-html-webpack-plugin": "^2.1.5",
    "terser-webpack-plugin": "^4.2.3",
    "vue-template-compiler": "^2.6.11",
    "webpack-bundle-analyzer": "^3.9.0",
    "cross-env": "^7.0.3"
  },
  "eslintConfig": {
    ...
  },
  "browserslist": [
    "> 1%",
    "last 2 versions",
    "not dead"
  ],
  "license": "Apache"
}

最终，npm install，可以发现我们构建注入的依赖，node_modules如图，已经变成了我们私有库的地址，接下来我们就可以在Branch_v8.8.3分支上修改源码了
