# Installing Node.js on z/OS
Before you install Zowe™, you must install IBM SDK for Node.js on the same z/OS server that hosts the Zowe Application Server. To install Node.js for Zowe, you can follow the steps in this topic or in the IBM SDK for Node.js - z/OS documentation.
Note: If you follow the steps in the Node.js documentation to install Node.js, you do NOT need to install Python, Make, Perl, or C/C++ runtime or compiler, which might be listed as prerequisites there. These software packages are NOT required by Zowe. If you can execute
node --version successfully, you have installed the prerequisites required by Zowe.
