sh:gnuplot:在Gnuplot + Xcode中找不到命令

有一个类似的问题要问我，但是答案还不是解决方案，因此，如果我能对此有所帮助，将不胜感激.

There was a similar question to mine however the answers were not quite solutions so if I could get some help with this it would be greatly appreciated.

问题在于，当我编译时，Xcode给出了上述的sh:gnuplot:命令找不到的错误.

The problem is that when I compile, Xcode gives the aforementioned error of sh: gnuplot: command not found.

我在终端中检查了which gnuplot，并且正如Macports所期望的那样，它在/opt/local/bin/gnuplot中.此外，printf("PATH=%s\n", getenv("PATH"));显示了我怀疑其中存在问题的路径PATH=/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin，但我不确定如何解决此问题.

I checked which gnuplot in terminal and as expected from macports it is in /opt/local/bin/gnuplot. Also printf("PATH=%s\n", getenv("PATH")); shows the path PATH=/Applications/Xcode.app/Contents/Developer/usr/bin:/usr/bin:/bin:/usr/sbin:/sbin I suspect therein lies the problem but I am not sure how to fix it.

提前谢谢！
