I have just upgraded Julia from v1.5.4 to v1.6.1. Everything was working OK in the previous version and it also works OK with the new version, **apart from Flux**. I had to `rm` Flux, otherwise, the list of errors was huge. I don’t know what is happening. Actually, this is the first time that I am having this situation. I don’t have CuArrays installed and do have CUDA v2.6.3 on my system. I had to `rm` Flux and tried to install its most recent version. Got this error (notice that if I `rm` TextParse, which is an interdependency of CSVFiles, I have to remove the entire package CSVFiles, and in this case the list of errors becomes huge):

Hello @VivMendes , I was able to add Flux package on my Windows 10 machine using a clean project folder in Julia 1.6.1 .

```julia
import Pkg
mkdir("flux")
pkg"activate flux"
pkg"add Flux"

```

Manifest.toml [here](https://gist.github.com/sosiristseng/24017465eb8ea90da14d8ba81e45494b)

It seems like there are some package(s) in your root project `(@v1.6)` blocking your installation.

@Wen-Wei_Tseng Thanks. I was able to install Flux in the usual manner. The only problem is that I had to rm CSVFiles.jl, because there is apparently a conflict between these two packages in Julia 1.6.1. I do not understand what’s happening and hope that this problem goes away in future developments because CSVFiles is a quite useful package. Even now, the problem continues to seem related to TextParse.
