Prerequisites
Install compiler tools
If you want features such as application profiling or monitoring, you may need to install compiler tools before you start. See Installing compiler tools for more information.
Set directory permissions
Warning: Changing privileges like this is appropriate only on your local development system. Never do this on a server system.
To install Node and StrongLoop , you need permissions to write to directories:
/usr/local/bin/usr/local/lib/node_modules
If you see errors such as:
npm ERR! Error: EACCES, mkdir '/usr/local/lib/node_modules/strongloop'
...
npm ERR! Please try running this command again as root/Administrator
...
Then you don’t have the required rights to create files or directories. Either change the rights for the specified directories, or run the command using sudo. In general, it’s better to fix the directory rights as follows:
$ sudo chown -R $USER /usr/local
This command makes your user account the owner of the /usr/local directory. Then you won’t ever have to use sudo to install Node or install packages globally with npm. For more information, see How to Node.
Warning:
DO NOT use the above chown command on the /usr/bin directory. Doing so can severely misconfigure your system.
If you have to use sudo, use the following command:
$ sudo npm install -g --unsafe-perm install strongloop
Install Node.js
If you haven’t already installed Node, download the native installer from nodejs.org and run it.
Tip: For best results, use the latest LTS (long-term support) release of Node.js.
Install StrongLoop
Follow these steps:
- Open a Terminal window.
-
Enter this command:
$ npm install -g strongloopIf you didn’t set your file and directory privileges as instructed above, use this command (not recommended):
$ sudo npm install -g strongloopNote: During installation, you may see a number of errors from
node-gypif you don’t have compiler tools installed. You can ignore the errors for now.
