Hi,

I just reinstalled julia, but now got the same error on precompilation of different Packages. For example when I try to use Plots, the following error shows:

```julia
ERROR: LoadError: LoadError: error compiling convert: error compiling cnvt: error compiling ^: could not load library "libopenlibm"

```

I did reinstall julia after I encountered this error but that did not help. Any Ideas to fix that?

Okay, I found the error. Julia was not in my PATH and so it couln’t find the library.
