Get into the habit of writing together! This is the 9th day of my participation in the "Nuggets Daily New Plan · April Update Challenge", click to view the details of the event .
We all know that many popular frameworks on the Internet basically follow 前后端the route of separation, which means that most programmers have to accept front-end technologies, such as: vue, reactetc. front-end frameworks ! ! ! ^_^
As we develop more projects, different projects use different frameworks, and there are also 本地开发环境equivalent restrictions, such as nodeversion restrictions, this is a comparison 头疼problem.
E.g:
- Project A, needs to be in v10.5.0
- Project B, needs to be in v12.16.1
That's disgusting for developers! ! ! =_=
If I want to run project A, I have to switch to node 10.5.0version; to run project B, I have to switch to node 12.16.1version. This 切换工作, you have to 重新install node! ! ! =_=
If you do this every time, you shouldn't be a waste of time! ! ! =_=
As one 牛皮的程序员, why can't we do this! ! !
According to what you said 切换, how can this be done in a comparatively 快捷way?
Not much nonsense, there must be, it is the protagonist nvmtool we are going to share today.
nvmThe tool is a nodeversion management tool that can help us quickly switch the local development environment node的版本.
nvm install
1. Download nvm
1. Download address
From githubabove, download the latest version: download address
Here, how do we choosenvm-setup.zip
注：本文下载版本：1.1.9（目前最新，目前时间2022-04-09）
2.安装nvm
解压安装：nvm-setup.zip，一步步安装即可，不需要改什么东西！！！(这很关键)
打开cmd，输入nvm命令，看到以下信息，表示已经安装成功了
注意：安装的时候，建议用默认的安装路径即可，不建议修改安装路径，否则会导致某些问题。不按照建议做的，后果自己承担哈！！！
二、配置加速镜像
因为nvm默认的下载地址，使用的是一个外国的地址，速度比较慢呀，这个是不能忍的啦！！！
咋们这里切换到淘宝的镜像，下载速度快到你不可信喔！！！^_^
配置方法：
打开nvm的安装路径，默认安装路径是：C:\Users\Administrator\AppData\Roaming\nvm
对settings.txt，进行修改，后面加上淘宝的node和npm镜像地址即可
root: C:\Users\Administrator\AppData\Roaming\nvm
path: C:\Program Files\nodejs
node_mirror: https://npm.taobao.org/mirrors/node/
npm_mirror: https://npm.taobao.org/mirrors/npm/
复制代码三、安装node
1.nvm安装命令：
nvm install v10.5.0
复制代码这里是因为npm无法下载，导致安装失败了。可能是github的地址不太稳定导致。
好家伙，npm安装失败了，这可咋整？别急，这里哥们还是有办法解决，接着往下！！！
这里分析一下，nvm下载的node，就会放到这个路径下面，那咋们岂不是可以自己下载node，然后放入到这个路径下，nvm就可以进行管理node的版本呢？好像就是这样...
那么这样的话，我们手动下载node，放入到这个路径下，不就好了？
手动下载nodejs10.5.0
因为node10.5.0通过nvm安装失败了，我们得清一下这个有问题的node
卸载命令：
nvm uninstall 10.5.0
复制代码同时把temp也删了
Then, unzip it directly node-v10.5.0-win-x64.zipand change the folder name tov10.5.0
Finally look at the effect:
nvm list //列出所有node版本
复制代码Good guy, this way nvmyou can manage this too node10.5.0, Niu Niu Niu! ! ! ^_^
Switch to use the specified version of node
nvm use 10.5.0
复制代码nodejsA star here indicates the version currently in use
In the same way, let's proceed to install: 12.16.1and16.14.0
The download address of the historical version of nodejs
switch to16.14.0
View node, npmversion, normal use
See, switching is so easy, 丝滑ah! ! ! Perfect! ! ! ^_^
To summarize the nvm command:
| Order | effect |
|---|---|
| nvm list | List all node versions |
| nvm use 10.5.0 | Switch the specified version of node |
| nvm install v10.5.0 | Install the specified node version |
| nvm uninstall v10.5.0 | Uninstall the specified node version |
Well, that's all for the basic installation and operation of nvm, and we can write code happily! ! ! ^_^
