How do you usually install node modules offline? [Recommended learning: "nodejs Tutorial"]

Preface

In daily development, we usually install it online. It is possible to install the node module, but it is not guaranteed that there will be a need for offline installation. For example, if the company's intranet is not connected to the Internet, what should I do if I need to install a module?

Today, I will summarize a method of offline installation of the node module by installing the global asar module offline.

Preparation

Installation environment: MacOS

Since it is an offline installation, you first need to download the corresponding module through the network. In this article, npm install -D asar is used to download the asar module and its dependencies. The file structure is as follows:

Offline installation of global asar

The principle of method one is the same as when we install the node module online, install it directly through npm intall -g XXX.

First, we create a new node_modules folder under the asar folder, and move all the folders under test/node_modules except .bin and asar to test/ Under the node_modules/asar/node_modules folder, the structure is as follows:

Execute the following command in the terminal (the path is test/node_modules/asar Absolute path):

 npm install -g /Users/code/test/node_modules/asar复制代码

Then execute asar -V in the terminal at any location to verify whether the installation is successful. The results are as follows:

means that the asar module has been successfully installed and you're done!

Notes

On MacOS, the global module installed through this method only generates a soft link to the global command. Verify as follows:

Execute where asar and get the result:

Then go to the path /usr/local/bin/asar to find asar and check Its attributes:

So, never delete or rename the test/node_modules/asar/ file path, otherwise the global asar will fail!

Under windows, after using this method, the entire asar folder is completely copied to AppData/Roaming/npm/node_modules. Deleting the original asar folder does not affect the use.

Summary

The above is a simple method to install the global node module offline. I hope it will be helpful to everyone!
