我试图使用ipython笔记本.我安装了所有依赖库.但是,在Ipython控制台中启动ipython或"savefig"功能时,我无法使用"--pylab = inline"选项.当我尝试执行其中任何一个时,由于执行matplotlib而返回错误消息"RuntimeError:无法创建写入结构".此外,来自notebookApp提示的警告说"libpng警告:使用libpng-1.2.41构建的应用程序,但运行1.5.13".
但是,我安装了最新的libpng(1.5.13),卸载了pp卸载的matplotlib,并重新安装了pp install的matplotlib(在构建过程中,我可以看到libpng1.5.13用于构建matplotlib).
我的系统配置是Mac OS X10.6,python2.7.有人有类似的经历或一些建议吗？
以下是回溯错误:
