下载Node源码

wget https://nodejs.org/dist/v12.16.3/node-v12.16.3.tar.gz

解压包，并进入解压的文件夹
```
tar xvf node-v12.16.3.tar.gz
```

cd node-v12.16.3


3. 安装`python gcc-c++ gcc make`等库

- gcc and g++ >= 6.3 or newer, or

- GNU Make 3.81 or newer

- Python 2.7

```bash
sudo yum install python gcc-c++ gcc make

// Ubuntu
sudo apt-get install build-essential 
sudo apt-get install gcc 
sudo apt-get install g++

安装devtoolset-8，会升级gcc https://www.softwarecollections.org/en/scls/rhscl/devtoolset-8/


# 1. Install a package with repository for your system:
# On CentOS, install package centos-release-scl available in CentOS repository:
$ sudo yum install centos-release-scl

On RHEL, enable RHSCL repository for you system:

$ sudo yum-config-manager --enable rhel-server-rhscl-7-rpms

2. Install the collection:

$ sudo yum install devtoolset-8

3. Start using software collections:

$ scl enable devtoolset-8 bash


5. 编译
```bash
$ ./configure

$ make -j4

安装
```
$ make install
```
检查是否安装成功
```
node -v
```

npm -v


8. 如果运行`node -v` 报错
```bash
-bash: /usr/bin/node: No such file or directory

查找一下node安装位置
```
whereis node
```

// 输出 node: /usr/local/bin/node

10. 增加软链接：`node`和`npm`到`/usr/bin`
```bash
sudo ln -s /usr/local/bin/node /usr/bin/node

sudo ln -s /usr/local/bin/npm /usr/bin/npm

再检查node和npm版本
```
node -v
```

npm -v

阿里云CentOS 7 / Ubuntu 安装Node #5

On RHEL, enable RHSCL repository for you system:

2. Install the collection:
