当我想从here

安装软件包wxPython-2.8.7.1.spkg时

在Sage的终端，它给了我一个语法错误。我在Sage终端上写的内容和结果如下：

sage: sage -i wxPython-2.8.7.1.spkg
------------------------------------------------------------
   File "<ipython console>", line 1
     sage -i wxPython-RealNumber('2.8').gen(7).1.spkg
                    ^
SyntaxError: invalid syntax

我也使用包的直接地址，但结果是一样的：

 sage: sage -i http://www.sagemath.org/packages/experimental/wxPython-2.8.7.1.s>
------------------------------------------------------------
   File "<ipython console>", line 1
     sage -i http://www.sagemath.org/packages/experimental/wxPython-RealNumber('2.8').gen(7).1.spkg
                ^
SyntaxError: invalid syntax

我还下载了包并使用了本地地址但结果是一样的。

您需要在启动 Sage之前从命令行执行此操作。否则你可以使用

sage: install_package("wxPython")

目前正在为我下载...然后失败了：

checking for GTK+ - version >= 2.0.0... no
*** Could not run GTK+ test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GTK+ is incorrectly installed.
configure: error:
The development files for GTK+ were not found. For GTK+ 2, please
ensure that pkg-config is in the path and that gtk+-2.0.pc is
installed. For GTK+ 1.2 please check that gtk-config is in the path,
and that the version is 1.2.3 or above. Also check that the
libraries returned by 'pkg-config gtk+-2.0 --libs' or 'gtk-config
--libs' are in the LD_LIBRARY_PATH or equivalent.

沿着这些方向，这是它在the list of experimental spkgs所说的内容，其中一个是：

这些都是实验！他们可能根本不会为你工作！使用风险自负！其中许多从未在任何平台上成功构建！

所以买家要小心！
