I performed the following operations, but Julia reported an error ```julia ]add UMAP ``` ERROR: Unsatisfiable requirements detected for package Reexport [189a3867]: Reexport [189a3867] log: ├─possible versions are: 0.2.0-1.2.2 or uninstalled ├─restricted by compatibility requirements with BetaML [024491cd] to versions: 0.2.0-1.2.2 │ └─BetaML [024491cd] log: │ ├─possible versions are: 0.1.0-0.5.5 or uninstalled │ ├─restricted to versions \* by an explicit requirement, leaving only versions 0.1.0-0.5.5 │ ├─restricted by compatibility requirements with Zygote [e88e6eb3] to versions: 0.2.0-0.5.5 or uninstalled, leaving only versions: 0.2.0-0.5.5 │ │ └─Zygote [e88e6eb3] log: │ │ ├─possible versions are: 0.1.0-0.6.29 or uninstalled │ │ ├─restricted by compatibility requirements with BetaML [024491cd] to versions: 0.4.0-0.6.29 │ │ │ └─BetaML [024491cd] log: see above │ │ ├─restricted by compatibility requirements with FillArrays [1a297f60] to versions: [0.1.0-0.3.1, 0.5.5-0.6.29] or uninstalled, leaving only versions: 0.5.5-0.6.29 │ │ │ └─FillArrays [1a297f60] log: │ │ │ ├─possible versions are: 0.2.0-0.12.7 or uninstalled │ │ │ └─restricted by compatibility requirements with NearestNeighborModels [636a865e] to versions: 0.9.0-0.12.7 │ │ │ └─NearestNeighborModels [636a865e] log: │ │ │ ├─possible versions are: 0.1.1-0.1.6 or uninstalled │ │ │ ├─restricted to versions \* by an explicit requirement, leaving only versions 0.1.1-0.1.6 │ │ │ └─restricted by compatibility requirements with MLJModelInterface [e80e1ace] to versions: 0.1.5-0.1.6 or uninstalled, leaving only versions: 0.1.5-0.1.6 │ │ │ └─MLJModelInterface [e80e1ace] log: │ │ │ ├─possible versions are: 0.1.0-1.3.3 or uninstalled │ │ │ ├─restricted by compatibility requirements with MLJFlux [094fc8d1] to versions: 0.3.0-1.3.3 │ │ │ │ └─MLJFlux [094fc8d1] log: │ │ │ │ ├─possible versions are: 0.1.0-0.2.5 or uninstalled │ │ │ │ ├─restricted to versions \* by an explicit requirement, leaving only versions 0.1.0-0.2.5 │ │ │ │ └─restricted by compatibility requirements with MLJModelInterface [e80e1ace] to versions: 0.1.10-0.2.5 or uninstalled, leaving only versions: 0.1.10-0.2.5 │ │ │ │ └─MLJModelInterface [e80e1ace] log: see above │ │ │ ├─restricted by compatibility requirements with NearestNeighborModels [636a865e] to versions: 0.3.5-1.3.3 │ │ │ │ └─NearestNeighborModels [636a865e] log: see above │ │ │ └─restricted by compatibility requirements with OutlierDetectionInterface [1722ece6] to versions: 1.3.0-1.3.3 │ │ │ └─OutlierDetectionInterface [1722ece6] log: │ │ │ ├─possible versions are: 0.1.0-0.1.4 or uninstalled │ │ │ └─restricted by compatibility requirements with OutlierDetectionNetworks [c7f57e37] to versions: 0.1.0-0.1.4 │ │ │ └─OutlierDetectionNetworks [c7f57e37] log: │ │ │ ├─possible versions are: 0.1.0 or uninstalled │ │ │ └─restricted to versions \* by an explicit requirement, leaving only versions 0.1.0 │ │ └─restricted by compatibility requirements with LoopVectorization [bdcacae8] to versions: [0.1.0-0.5.2, 0.5.14-0.6.29] or uninstalled, leaving only versions: 0.5.14-0.6.29 │ │ └─LoopVectorization [bdcacae8] log: │ │ ├─possible versions are: 0.1.0-0.12.90 or uninstalled │ │ └─restricted by julia compatibility requirements to versions: 0.9.0-0.12.90 or uninstalled │ └─restricted by compatibility requirements with MLJModelInterface [e80e1ace] to versions: [0.1.0-0.3.0, 0.5.0-0.5.5] or uninstalled, leaving only versions: [0.2.0-0.3.0, 0.5.0-0.5.5] │ └─MLJModelInterface [e80e1ace] log: see above ├─restricted by compatibility requirements with OutlierDetectionInterface [1722ece6] to versions: 1.0.0-1.2.2 │ └─OutlierDetectionInterface [1722ece6] log: see above └─restricted by compatibility requirements with NearestNeighborDescent [dd2c4c9e] to versions: 0.2.0 — no versions left └─NearestNeighborDescent [dd2c4c9e] log: ├─possible versions are: 0.1.0-0.3.4 or uninstalled ├─restricted by compatibility requirements with UMAP [c4f8c510] to versions: 0.1.4-0.3.4 │ └─UMAP [c4f8c510] log: │ ├─possible versions are: 0.1.0-0.1.8 or uninstalled │ ├─restricted to versions \* by an explicit requirement, leaving only versions 0.1.0-0.1.8 │ └─restricted by compatibility requirements with Distances [b4f34e82] to versions: 0.1.8 or uninstalled, leaving only versions: 0.1.8 │ └─Distances [b4f34e82] log: │ ├─possible versions are: 0.7.0-0.10.6 or uninstalled │ ├─restricted to versions \* by an explicit requirement, leaving only versions 0.7.0-0.10.6 │ └─restricted by compatibility requirements with OutlierDetectionNeighbors [51249a0a] to versions: 0.10.0-0.10.6 │ └─OutlierDetectionNeighbors [51249a0a] log: │ ├─possible versions are: 0.1.0 or uninstalled │ └─restricted to versions \* by an explicit requirement, leaving only versions 0.1.0 └─restricted by compatibility requirements with Distances [b4f34e82] to versions: 0.3.3-0.3.4 or uninstalled, leaving only versions: 0.3.3-0.3.4 └─Distances [b4f34e82] log: see above thanks! ---

I didn’t look at all that super carefully but are you in a particular project or is that just in the base Julia environment? I’d suggest to `] activate .` and try to install Umap in a clean environment.
