Better way to install nodejs is via nvm. Here you can install/use multiple version of nodejs in a machine.
安装 nodejs 的更好方法是通过 nvm。在这里，您可以在一台机器上安装/使用多个版本的 nodejs。

然后
nvm install $vesionNo
nvm use $versionNO
// for default
nvm alias default node

In some Linux distributions, node is installed on /usr/bin/nodejsand not on /usr/bin/node.
在某些 Linux 发行版中，node 安装/usr/bin/nodejs在/usr/bin/node.
What I did, is install nodejs-legacy, and it solved the problem. It creates a symlink from /usr/bin/nodejsto /usr/bin/node.
我所做的是安装 nodejs-legacy，它解决了问题。它创建了一个从/usr/bin/nodejs到的符号链接/usr/bin/node。
So, what I recommend (as the easiest solution) is to install nodejs-legacy:
所以，我推荐的（作为最简单的解决方案）是安装nodejs-legacy：
sudo apt-get install nodejs-legacy

If there is a character or a space other than the English characters from the windows user name, it can also be caused by this.
如果windows用户名中有英文字符以外的字符或空格，也可能是这个原因。
I'm talking about the installation of global packages. If you are installing a package on a specific project, it may also be caused by the lack of package.json.
我说的是全局包的安装。如果是在特定项目上安装包，也可能是缺少 package.json 导致的。
