全局安装节点 package 没有互联网服务器错误：没有这样的文件或目录

Question

I'm working with a nodejs project. The project has local and global dependency of npm packages. The server where we want to deploy the project doesn't have the internet connection. So, we're trying to install npm packages on the server.

For local dependency, copy local dependency from local machine to server works. However, We are struggling to install global packages.

We're using below global packages:

1. Truffle v4.1.12.
2. PM2

To install global packages we have tried several things like:

Copy executable to /user/local/bin from local machine and
Copy content from lib/node_modules/truffle to /usr/local/lib/node_modules/truffle

However, it didn't work. Shows error as below even though the file cli.bundled.js is located.

[redhat@redhat8 ~]$ truffle -v
/usr/local/bin/truffle: line 1: ../lib/node_modules/truffle/build/cli.bundled.js: No such file or directory

I thought it's issue of symbolic link so tried to create it

ln -s /usr/local/bin/truffle /usr/local/lib/node_modules/truffle/build/cli.bundled.js

However still it's showing same error. Is there anyway to make it work?

Answer 1

Instead of installing as a global module, which will require you to understand more about how your target system is configured, install it as a peer dependency.

npm install --save-peer pm2 truffle

This will place the executables in node_modules . To invoke them, make sure you are in that directory with the package.json file. (This is important to note for startup scripts and things like that, of course.) You can then invoke the executables with npx :

$ npx truffle -v
npx truffle -v
