将 PSModulePath 变量设置为 Linux - PowerShell 7

Question

I am trying to update the PSModulePath variable on Linux (CentOS 7.9). I have tried:

# Check current path(s)
$env:PSModulePath
/opt/microsoft/powershell/7-lts/Modules

# Update the variable
$env:PSModulePath += ":/opt/MyModules"
# Confirm the update
$env:PSModulePath
/opt/microsoft/powershell/7-lts/Modules:/opt/MyModules

All working OK. Now I try to relaunch PowerShell:

exit
pwsh
$env:PSModulePath
/opt/microsoft/powershell/7-lts/Modules

The setting does not persist. How can I fix this?

Using: PowerShell 7

Linux CentOS 7.9

Answer 1

Assigning to $env:PSModulePath sets the process -scoped copy of the PSModulePath environment variable, which is by definition not persisted; it disappears when the process terminates.

To make persistent changes, you have two options:

• Use your system's features for defining persistent environment variables.

  • For instance, for Ubuntu see this askubuntu.com answer .

• Add the modification statement to your PowerShell $PROFILE file (there are multiple profiles, based on whether they apply to all vs. the current user, and all vs. specific PowerShell host environments).
