Question

如果我执行npm install mongodb，则会安装所需版本的mongodb而不会出现问题：

- bson@0.1.5 node_modules/mongodb/node_modules/bson
mongo-invoices@0.0.0 /home/lorencm/Downloads/mongo-invoices
└─┬ mongodb@2.1.6 
  ├── es6-promise@3.0.2 
  ├─┬ mongodb-core@1.3.1 
  │ ├── bson@0.4.21 
  │ └─┬ require_optional@1.0.0 
  │   ├── resolve-from@2.0.0 
  │   └── semver@5.1.0 
  └─┬ readable-stream@1.0.31 
├── core-util-is@1.0.2 
├── inherits@2.0.1 
├── isarray@0.0.1 
└── string_decoder@0.10.31

只要存储了package.json中的所有依赖项（见下文）并使用npm install，我就会失败（见下文）来安装mongodb@2.1.6，而是安装mongodb@1.1.11 }：

为什么不安装我在package.json中指定的版本？

Answer 1

由于npm-shrinkwrap.json文件包含以下内容，应用程序无法安装var loader = new THREE.ObjectLoader(); loader.load("zebra.json",function ( obj ) { scene.add( obj ); });版本：

此命令会锁定程序包依赖项的版本，以便您可以精确控制安装程序包时将使用的每个依赖项的版本。

如果您检查2.1.6的{{3}}，则会发现mongo-invoices的指定版本为mongodb

package.json中指定的Mongodb版本无法安装
