ERROR: Invalid requirement, on Isaac Sim Pip install

[leonorehamer]

Following the official guide and using miniconda on Windows. I previously installed the Cuda 12 option & did the PIP update (pip-25.1)

Yet get this error on running the install the Isaac Sim packages command.

(env_isaaclab) C:\Users\leono>pip install ‘isaacsim[all,extscache]==4.5.0’ --extra-index-url https://pypi.nvidia.com
ERROR: Invalid requirement: “‘isaacsim[all,extscache]==4.5.0’”: Expected package name at the start of dependency specifier
‘isaacsim[all,extscache]==4.5.0’

Fixed by running the same command in an Anaconda Powershell, I assume it was merely this that helped, as I did Install Visual Studio also before doing this
