nodejs installation module stuck

Node.js has become one of the most popular languages ​​​​for front-end and back-end developers, and sometimes you can encounter difficulties when installing modules. In this article, we will discuss how to solve the problem of Node.js installation module getting stuck.

First, let’s understand how the Node.js installation module works. Node.js is based on an event-driven model, where every request is asynchronous and they cannot block the main thread. When you need to install a module, it usually downloads some packages and performs some complex operations, which may take some time to complete. Due to the nature of Node.js, the installation process may be stuck due to network problems or some other issues. When this happens, we need to address it.

1. Check the network connection

Node.js needs to access the remote server to download and install modules, so checking whether the network connection is normal is the first step. If your device isn't connected to the internet or the connection is unstable or slow, you'll need to reconnect and make sure it's working properly.

2. Clear npm cache

The npm cache is stored locally. If there is a problem with the cache data used to install the module, the installation may be stuck. In order to solve this problem, we need to try clearing the npm cache.

Enter the following command on the command line:

npm cache clean -f

This will delete the local cache and reinstall the required modules. Then, try installing the module again.

3. Use Taobao mirror

When you use npm to install modules, it will download the installation package from the official source by default. If your network connection is unstable or slow, you may need to use Taobao mirroring. This process sets npm to use the Taobao mirror. Enter the following command on the command line:

npm install -g cnpm --registry=https://registry.npm.taobao.org

Then, you can use cnpm instead of npm to install. For example:

cnpm install your-package-name

4. Modify the default download source of Node.js

When you install a module through npm, it will default from http://registry.npmjs.org /download. However, since the official source is in a foreign server, when the network is not smooth, the download will be ineffective. Therefore, the source can be modified to a domestic server, which can speed up the download. Specifically, you can use the following two methods:

4.1 Modify the npm source

Use the command line tool to enter the working directory where the module needs to be installed, and then enter the following command:

npm config set registry http://registry.npm.taobao.org/

This will Change the default download source of npm to the Taobao mirror source.

4.2 Use the nrm tool

You can use the nrm tool to manage and switch different source addresses. First, you need to install nrm globally:

npm install -g nrm

Then, enter the following code on the command line to view the current npm source:

nrm ls

Next, modify the npm source to the Taobao image through the following command:

nrm use taobao

Now try to reinstall the module. You should find it to be faster and speed up your development productivity.

Summary

Node.js is a powerful language, and its functions can be expanded through NPM installation modules. However, if the installation is stuck, it may affect development. efficiency. By clearing the npm cache, using Taobao mirrors, modifying the default download source of Node.js, etc. to solve this problem, you can effectively improve the development efficiency of Node.js.
