node.js - Installing node package globally without internet on server error: No such file or directory

问题描述

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?

解决方案

与其作为全局模块安装（这需要您更多地了解目标系统的配置方式），不如将其安装为对等依赖项。

npm install --save-peer pm2 truffle

这会将可执行文件放在node_modules. 要调用它们，请确保您位于该package.json文件所在的目录中。（这对于启动脚本和类似的东西来说很重要，当然。）然后您可以使用以下命令调用可执行文件npx：

$ npx truffle -v
npx truffle -v
