Install the nodejs official website under centos today, download the installation package,
decompress it
, throw it on a remote machine,
add environment variables,
and execute

*******/npm: line 1: ../lib/node_modules/npm/bin/npm-cli.js: No such file or directory
An error was reported.
Take a look, there is no such file?
Go to the corresponding directory to see, there is this file,
that is the problem of the path,
go to the bin and look at the npm file,
what is the relative path in it, change it to an absolute path
and execute
>npm -v

Why can’t I get the version number
and try another command
npm install
npm version
Why do they all return the above thing?
I searched online and found some solutions, such as executing a script or something.
I don’t think it should be. Nodejs has been developed for so long, how could it be possible that even the installation of linux is still a semi-finished product? This problem must exist in me
turn back and start over
Looking back at the downloaded node installation package, I found a problem
Use the software to open the installation package.
The npm and npx files in the bin directory are both 0 bytes
, but the one I uploaded is 38 bytes.
It turns out that the two file systems of windows and linux are different.
These two files are two linux soft links.
Windows does not have the same thing as linux soft links.
Therefore, when decompressing, these two files become internal inclusions. the text of the link address
../lib/node_modules/npm/bin/npm-cli.js
When we use this to execute, we will naturally encounter the problem of relative path
The real solution is to unzip it under linux
tar -xJvf node-v10.16.3-linux-x64.tar.xz
fix environment variables
>node -v
v10.14.2
>npm -v
6.4.1
you're done
