Problems in installing and using some packages (Failed to precompile)

New to Julia
1

Hi!
I have been having trouble using quite a few of the packages I have installed, including: Gadfly, Blink and Cairo. In all cases, I received a message stating that Julia had failed to precompile the package. In a similar vain, Julia had failed to precompile PlotlyJS when I tried setting it as a backend. In some of the cases I get an error message stating that one of the packages is not properly installed, while suggesting the command required to install it. However, following the instructions yields no success…

I am using Julia 6 on a mac. I am running it using Jupiter notebook.

Example of error messages that I have been getting:
Trying to use Cairo I am getting:

===============================================================
INFO: Precompiling module Cairo.
ERROR: LoadError: Cairo not properly installed. Please run
Pkg.build(“Cairo”)
Stacktrace:

Failed to precompile Cairo to /Users/assa/.julia/lib/v0.6/Cairo.ji.

As I run Pkg.build(“Cairo”) I get:

WARNING: Cairo and Homebrew had build errors.

  • packages with build errors remain installed in /Users/assa/.julia/v0.6
  • build the package(s) and all dependencies with Pkg.build("Cairo", "Homebrew")
  • build a single package by running its deps/build.jl script
    ================================================================================

Because I keep encountering similar mistakes with a few different packages I tend to think all is a part of a more general problem in the I am using (or the way I have installed) Julia. I should mention that other packages (e.g: Distributions, DataFrames, Plots…) are working ok. Would appreciate any help.

Many thanks!

After installing Julia-Pro the problem was solved.
