在osx 10.11中安装wxPython [英] Install wxPython in osx 10.11

问题描述

当我尝试安装wxPython时，它显示错误:

When I try to install wxPython, it shows an error:

> The Installer could not install the software because there was no
> software found to install.

我该如何解决?

推荐答案

wxPython使用的是旧脚本，并根据此

wxPython is using a legacy script, and according to this technical note bundle installers were deprecated and are (as of El Capitan release) unsupported:

捆绑式安装程序包是不再支持的旧版过渡帮助.也不再支持PackageMaker.现在必须使用productbuild之类的工具转换为平面文件安装程序包.

Bundle-style installer packages are a legacy transition aid that is no longer supported. PackageMaker is also no longer supported. It is now necessary to convert to flat-file installer packages using tools like productbuild.

这给您两个选择，

1. 将安装程序转换为平面软件包.
2. 编译wxWidgets并在本地安装.

要实现前者，请按照以下说明进行操作:

To achieve the former, follow these instructions:

0 )假设您已经安装了dmg，并且已经将pkg文件夹移动到了工作地点.

0) Let's assume that you have already mounted the dmg and you have moved the pkg folder to a working place.

cd ~/repack_wxpython
cp -r /Volumes/wxPython/wxPython-ABC.pkg .

1 )，使用pax实用程序将有效负载文件(pax.gz)从Contents/Resources提取到将成为新软件包根目录的文件夹中.

1) Use the pax utility to extract the payload file (pax.gz) from Contents/Resources to a folder that will become the root of your new package.

mkdir pkg_root
cd pkg_root
pax -f ../wxPython-ABC.pkg/Contents/Resources/wxPython-ABC.pax.gz -z -r
cd ..

2 )，根据扁平包装的要求，在脚本文件夹中将捆绑软件的preflight/postflight脚本重命名为preinstall/postinstall脚本.

2) Rename the bundle's preflight/postflight scripts, to preinstall/postinstall scripts, as required for flat packages, in a scripts folder.

mkdir scripts
cp wxPython-ABC.pkg/Contents/Resources/preflight scripts/preinstall
cp wxPython-ABC.pkg/Contents/Resources/postflight scripts/postinstall

3 )使用pkgbuild工具创建扁平包装:

3) Create the flat package using the pkgbuild tool:

pkgbuild --root ./pkg_root --scripts ./scripts --identifier com.wxwidgets.wxpython wxPython-ABC.pkg

这是pkbuild命令的文档，以防您要自定义传递的参数.

This is the documentation of the pkbuild command in case you want to customize the passed parameters.

注意事项:原始捆绑包中包含License.rtf和Welcome.txt文件，这些文件不包含在平面软件包中.这些需要通过定义 productbuild 命令.

Caveats: The original bundle package contains a License.rtf and a Welcome.txt files that are not included in the flat package. Those need to be added by defining a custom XML file and creating another package using the productbuild command.
