Create a command file to set environment variables and open applications

Create an executable file to launch the Unity Hub with specific environment variables in the same session.
阅读时间4 分钟最后更新于 1 个月前
When you define environment variables from a command line, the values don't persist across sessions. A process can use those environment variables if it’s launched from the same session, but after you end that session, you must define the values again.
Administrators can set environment variables at the operating system level. If that's not an option, you can create a command file to set environment variables and launch a Unity application, such as the Hub, from the same session. This executable file becomes a reusable method for opening the Unity Hub with the environment variables required by your environment.
重要
After the command file is created, be sure to always launch the Unity Hub using that file, instead of standard methods, such as the Start menu (Windows) or the Applications folder (macOS).

Before you begin

Decide which environment variables you need to set, and include only the required environment variables:
  • If your environment doesn’t support automatic proxy configuration, set the 
    HTTP_PROXY
    and 
    HTTPS_PROXY
    environment variables to identify your web proxy. For more information, refer to Use environment variables to identify your web proxy.
  • If your environment uses a Unity Licensing Server for floating licenses, set the 
    NO_PROXY
    environment variable.
  • If your environment uses a web proxy with SSL inspection, set the 
    NODE_EXTRA_CA_CERTS
    environment variable. For more information, refer to Trusting the web proxy security certificate.
If you’re setting the 
HTTP_PROXY
and 
HTTPS_PROXY
environment variables, make sure you use the proper value to include or exclude authentication information.

Create a command file (Windows)

These instructions create an executable file named 
launchUnityHub.cmd
.
  1. Close the Unity Hub, if it’s running.
  2. Open a text editor such as Notepad.
  3. Enter the following text, adjusting as necessary:
    • Include only the required environment variables, and set their values properly. Refer to Before you begin.
    • Set the Hub path to match the location of your Unity Hub program file.
    @echo offREM *** NOTE: Add the next 3 lines only if you’re not using Automatic Proxy Configurationset HTTP_PROXY=http://<username>:<password>@<proxy_name_or_IP_address>:8080set HTTPS_PROXY=http://<username>:<password>@<proxy_name_or_IP_address>:8080set NO_PROXY=<licensing_server_name_or_IP_address>REM *** NOTE: Add the following line only if your web proxy uses SSL inspectionset NODE_EXTRA_CA_CERTS=<path_to_pem_file>start "" "C:\Program Files\Unity Hub\Unity Hub.exe"
    注意
    If there are spaces in the path, you must use double quotes around the path to the program.
  4. Save the file to a location where you can find it (such as the 
    Desktop
    ), and make sure the file has the 
    .cmd
    extension (for example, 
    launchUnityHub.cmd
    ), not 
    launchUnityHub.txt
    or 
    launchUnityHub.cmd.txt
    .
  5. Double-click 
    launchUnityHub.cmd
    to launch the Unity Hub with the required environment variables intact.
The Unity Hub passes these environment variables to any process it spawns, such as the Unity Editor.

Create a command file (macOS and Linux)

These instructions create an executable file named 
launchUnityHub.command
.
  1. Close the Unity Hub, if it’s running.
  2. Open a Terminal window.
  3. Run the following command, adjusting as necessary:
    • Include only the required environment variables, and set their values properly. Refer to Before you begin.
    • Set the Hub path to match the location of your Unity Hub application.
    echo '#!/usr/bin/env bash# *** NOTE: Add the next 3 lines only if you’re not using Automatic Proxy Configurationexport HTTP_PROXY=http://<username>:<password>@<proxy_name_or_IP_address>:8080export HTTPS_PROXY=http://<username>:<password>@<proxy_name_or_IP_address>:8080export NO_PROXY=<licensing_server_name_or_IP_address># *** NOTE: Add the following line only if your web proxy uses SSL inspectionexport NODE_EXTRA_CA_CERTS=<path_to_pem_file>nohup "/Applications/Unity Hub.app/Contents/MacOS/Unity Hub" &>/dev/null &' > launchUnityHub.command
    注意
    If there are spaces in the path, you must use double quotes around the path to the application.
  4. Run the following command to make 
    launchUnityHub.command
    executable:
    chmod +x launchUnityHub.command
  5. Move the 
    launchUnityHub.command
    file to a convenient location (for example, the 
    Desktop
    ), if you prefer.
  6. Double-click 
    launchUnityHub.command
    to launch the Unity Hub with the required environment variables intact.
The Unity Hub passes these environment variables to any process it spawns, such as the Unity Editor.
