小编Ric*_*lev的帖子

我试过n latest

cp: cannot create directory '/usr/local/lib/node_modules': Permission denied
cp: cannot create regular file '/usr/local/bin/node': Permission denied
cp: cannot create symbolic link '/usr/local/bin/npm': Permission denied
cp: cannot create symbolic link '/usr/local/bin/npx': Permission denied
cp: cannot create directory '/usr/local/include/node': Permission denied

我已经制作了文件夹

sudo mkdir -p /usr/local/n && chown -R $(whoami) /usr/local/n/

我使用的是 Ubuntu 18.04。

使用须藤

sudo n latest
sudo: n: command not found

我ssh编辑了我的流浪机器。

  System load:  0.13              Processes:           169
  Usage of /:   6.6% of 61.80GB   Users logged in:     0
  Memory usage: 76%               IP address for eth0: 10.0.2.11
  Swap usage:   16%               IP address for eth1: 192.100.0.12

这两个私有IP有什么区别？

这是我尝试过的：

$ mailx -s "test email" cloud
Cc: 
"again and agina"
.
EOT

或者，

$ mailx -s "test email" cloud
Cc: 
"this is the first email"
<< EOT

但按下后Enter什么反应也没有。为什么？
