libnlopt.so.0 無法打開共享對象文件

這個錯誤是什麼意思？

ImportError: libnlopt.so.0: cannot open shared object file: No such file or directory

我試圖執行需要 nlopt的 python2腳本。

nlopt 由

pip2 install --user nlopt

這意味著無法載入共享庫。您可以通過以下方式解決問題：

sudo apt-get install libnlopt0

然後執行你的命令。

也就是說，如果您正在執行 Debian/Ubuntu 或衍生產品。如果沒有，請使用您的發行版用來添加包的任何命令，在這種情況下為libnlopt0.
