Julia-JuMP錯誤解決NLMIP：錯誤：編譯錯誤read_osrl_file !:無法加載模塊C：\ Users：無錯

我最近在Julia開發了一個JuMP程序（文件「main_lac.jl」構建了問題和文件「 lac.jl「解決它）來建模和解決一個混合整數非線性規劃問題。 Everithing幾天前工作得很好，我可以用CoinOptServices.jl包使用Bonmin和Couenne求解器來解決問題。奇怪現在我啓動程序時出現以下錯誤。下面是我得到朱莉婭：Julia-JuMP錯誤解決NLMIP：錯誤：編譯錯誤read_osrl_file !:無法加載模塊C： Users：無錯

我試圖重新安裝朱莉婭但沒有工作。我在Windows 8.1 64位下工作。注意：Pkg.test（「Cbc」）在Julia中出現相同的錯誤（錯誤編譯read_osrl_file！...）

任何幫助，將不勝感激。

謝謝

嘗試使用BonminNLSolver和CouenneNLSolver求解從AmplNLWriter包。請注意，這些求解器使用由CoinOptServices安裝的相同二進制文件。

與此同時，它看起來像這個錯誤是關於CoinOptServices.jl open issue。

謝謝。我遵循了你指出的[討論]（https://github.com/JuliaOpt/CoinOptServices.jl/issues/7）中的步驟，現在正在運行正常。 –
