感謝 yungyuc，不過我之前都使用 tarball 安裝，大概是因為這樣，整個相依性都掛了，搞到不清楚到底是誰有問題，後來決定整個重來，除了 networkx、psyco 之外，全都使用系統套件安裝，總共安裝了 numpy、matplotlib、tkinter、scipy 及其套件，像是 pygtk、pyobject、pycairo、gtk、tk、tcl 之類的全都順便安裝，因為不確定可能會少什麼的情況下，只好全部都安裝，以確保不會少東西，不過還是出現了以下錯誤： $HOME=/root CONFIGDIR=/root/.matplotlib matplotlib data path /usr/lib64/python2.5/site-packages/matplotlib/mpl-data loaded rc file /usr/lib64/python2.5/site-packages/matplotlib/mpl-data/matplotlibrc matplotlib version 0.98.1 verbose.level helpful interactive is False units is False platform is linux2 Using fontManager instance from /root/.matplotlib/fontManager.cache numerix numpy 1.2.0 Traceback (most recent call last): File "1.py", line 1, in <module> from pylab import * File "/usr/lib64/python2.5/site-packages/pylab.py", line 1, in <module> from matplotlib.pylab import * File "/usr/lib64/python2.5/site-packages/matplotlib/pylab.py", line 247, in <module> from matplotlib.pyplot import * File "/usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 39, in <module> new_figure_manager, draw_if_interactive, show = pylab_setup() File "/usr/lib64/python2.5/site-packages/matplotlib/backends/__init__.py", line 20, in pylab_setup globals(),locals(),[backend_name]) File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_gtkagg.py", line 10, in <module> from matplotlib.backends.backend_gtk import gtk, FigureManagerGTK, FigureCanvasGTK,\ File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_gtk.py", line 7, in <module> import gtk; gdk = gtk.gdk File "/usr/lib64/python2.5/site-packages/gtk-2.0/gtk/__init__.py", line 79, in <module> _init() File "/usr/lib64/python2.5/site-packages/gtk-2.0/gtk/__init__.py", line 67, in _init _gtk.init_check() RuntimeError: could not open display 查了資料後發現，問題還是在 backend，安裝好的 matplotlibrc 初始設定是 GTKAgg，於是我就改成 TkAgg， $HOME=/root CONFIGDIR=/root/.matplotlib matplotlib data path /usr/lib64/python2.5/site-packages/matplotlib/mpl-data loaded rc file /root/.matplotlib/matplotlibrc matplotlib version 0.98.1 verbose.level helpful interactive is False units is False platform is linux2 Using fontManager instance from /root/.matplotlib/fontManager.cache numerix numpy 1.2.0 backend TkAgg version 8.5 Traceback (most recent call last): File "1.py", line 2, in <module> plot([1,2,3]) File "/usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 1947, in plot b = ishold() File "/usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 396, in ishold return gca().ishold() File "/usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 496, in gca ax = gcf().gca(**kwargs) File "/usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 218, in gcf return figure() File "/usr/lib64/python2.5/site-packages/matplotlib/pyplot.py", line 204, in figure **kwargs) File "/usr/lib64/python2.5/site-packages/matplotlib/backends/backend_tkagg.py", line 87, in new_figure_manager window = Tk.Tk() File "/usr/lib64/python2.5/lib-tk/Tkinter.py", line 1636, in __init__ self.tk = _tkinter.create(screenName, baseName, className, interactive, wantobjects, useTk, sync, use) _tkinter.TclError: no display name and no $DISPLAY environment variable 依然有問題，後來看到裡面支援比較多的是 Cairo 和 GDK，於是就改成 Cairo 來試試，想不到就可以正確的把圖 show() 出來了。 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 163.25.118.144
