请按照此步骤重新安装节点模块并进行更新

即使node_modules文件夹不存在也可以工作。现在同步执行以下命令。你也可以使用“npm update”，但我认为这是更可取的方式

npm outdated // not necessary to run this command, but this will show outdated dependencies

npm install -g npm-check-updates // to install the "ncu" package

ncu -u --packageFile=package.json // to update dependencies version in package.json...don't run this command if you don't need to update the version

npm install: will install dependencies in your package.json file.

如果你对包中依赖项的版本没有问题。Json文件，不需要遵循这些步骤，只需运行

 npm install

npm更新了用于安装的CLI命令，并添加了——force标志。

npm install --force

——force(或-f)参数将强制npm获取远程资源，即使磁盘上存在本地副本。

参见npm install

你可以用一个简单的命令来做到这一点:

npm ci

以下是npm ci文档的节选:

In short, the main differences between using npm install and npm ci are: The project must have an existing package-lock.json or npm-shrinkwrap.json. If dependencies in the package lock do not match those in package.json, npm ci will exit with an error, instead of updating the package lock. npm ci can only install entire projects at a time: individual dependencies cannot be added with this command. If a node_modules is already present, it will be automatically removed before npm ci begins its install. It will never write to package.json or any of the package-locks: installs are essentially frozen.

你可以在Windows上使用

(if exist node_modules rmdir node_modules /q /s) && npm install

删除node_modules目录，然后执行NPM安装。安装前删除可确保重新安装所有包。

从npm cli v6.5.0开始，你可以使用backronym:

npm clean-install
