Official website download: http://nodejs.cn/download/

Select other version download address:https://nodejs.org/zh-cn/download/releases/

Select the version and click to download

Then download the suffix nameFor msi, because the installation is simple

Select OKBrainless installation after address

Second, create a folder
After the installation is complete, we open its directory to create two folders (need to configure environment variables later)
node_cache
node_global

Third, configure the storage path and cache of the global module of npmThe path of
win+r enter cmd to open the command prompt window, enter:

npm config set prefix "Select the path to the node_global file just created"npm config set cache "select the path to the node_cache file just created"

Note: The path needs to be enclosed in double quotation marks, as shown in the figure:

Fourth: Enter the following command on the command line to install express (Note: "-g" means to install in the global directory, which is the node_global set above)
This stepIt can prove that the cnpm downloaded later will be in this directory

npm install express -g

Then we open the installation directory of nodejs, find the node_modules under the created node_global folder, and see if there is the express you just downloaded

Five, configure environment variables
Add node_modules under the node_global folder just created in the system environment variables

Six, download cnpm
atContinue to enter the command line:

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

No need to add registry=https://registry.npm.taobao.org

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
