# Supported Node.js versions
The following Node.js versions are supported to run Zowe. See the Hardware and software prerequisites section for the prerequisites that are required by Zowe.
The corresponding IBM Knowledge Center for Node.js - z/OS lists all the prerequisites for Node.js. Some software packages, which might be listed as prerequisites there, are NOT required by Zowe. Specifically, you do NOT need to install Python, Make, Perl, or C/C++ runtime or compiler. If you can run
node --version successfully, you have installed the prerequisites required by Zowe.
Node.js Version 6
- z/OS V2R2 with PTF UI46658 or z/OS V2R3
Node.js Version 8
- z/OS V2R2: PTFs UI62788, UI46658, UI62416 (APARs PH10606, PI79959, PH10740)
- z/OS V2R3: PTFs UI61308, UI61376, and UI61747 (APARs PH07107, PH08353, and PH09543)
Known issue: There is a known issue with node.js v8.16.1 and Zowe desktop encoding. See the GitHub issue for details.
Workaround: Use node.js v8.16.2 or later, which is available at https://www.ibm.com/ca-en/marketplace/sdk-nodejs-compiler-zos. Download the

Create the following ICSF Key Data Sets:
Cryptographic Key Data Set (CKDS)
Public Key Data Set (PKDS)
(Optional) If you want to have PKCS#11 support through ICSF, you should create Token Key Data Set (TKDS)
Copy ICSF Installation Options sample (

Note: You might need IPL before starting ICSF.
# Installing the PAX edition of Node.js - z/OS
Follow these steps to install the PAX edition of Node.js - z/OS to run Zowe.
Download the pax.Z file to a z/OS machine.
Extract the pax.Z file inside an installation directory of your choice. For example:
pax -rf <path_to_pax.Z_file> -x pax
Add the full path of your installation directory to your PATH environment variable:
Run the following command from the command line to verify the installation.
If Node.js is installed correctly, the version of Node.js is displayed.
After you install Node.js, set the NODE_HOME environment variable to the directory where Node.js is installed. For example,
# Installing the SMP/E edition of Node.js - z/OS
To install the SMP/E edition of Node.js, see the documentation for IBM SDK for Node.js - z/OS. Remember that the software packages Perl, Python, Make, or C/C++ runtime or compiler that the Node.js documentation might mention are NOT needed by Zowe.
