How to install the specified version package with NPM and view the version number

In the process of Vue development, sometimes we need to install the specified version of the package.

For example: install bootstrap version 4.6.1

npm install [email protected]

If the version number is not followed (@4.6.1), then the latest version is installed by default.Different package version numbers may be specified differently!

For example, install without version number by default:

npm install bootstrap

Latest version installed: 5.1.3(2022-04-28)

Sometimes it may be necessary to install an earlier version due to compatibility or testing issues. Record the above method.

View the version numbers of installed packages: list

npm list bootstrap

View Vue version number:

npm list vue

If you install a package back and forth multiple times, it is recommended to uninstall the original package before installation, and then reinstall the new package. Uninstall the command:

npm uninstall bootstrap

Let me introduce myself first. The editor graduated from Shanghai Jiaotong University in 2013. I worked in a small company and went to big factories such as Huawei and OPPO. I joined Alibaba in 2018, until now.I know that most junior and intermediate java engineers want to upgrade their skills, they often need to explore their own growth or sign up to study, but for training institutions, the tuition fee is nearly 10,000 yuan, which is really stressful.Self-learning that is not systematic is very inefficient and lengthy, and it is easy to hit the ceiling and the technology stops.Therefore, I collected a "full set of learning materials for java development" for everyone. The original intention is also very simple. I hope to help friends who want to learn by themselves but don't know where to start, and at the same time reduce everyone's burden.Add the business card below to get a full set of learning materials
