Question

我正在尝试运行setup.py脚本（mnemosyne）。脚本失败了，我很确定我知道如何解决问题，如果我只能找到要编辑的文件。问题是回溯指向一个不存在的文件：

  File "build/bdist.macosx-10.5-x86_64/egg/macholib/MachOGraph.py", line 49, in locate
    loader=loader.filename)
TypeError: dyld_find() got an unexpected keyword argument 'loader'

我认为应该是loader_path。问题是MachOGraph.py文件不存在 - 不在我当前路径的任何地方，或者在我的anaconda发行版中。有一个build/bdist.macosx-10.5-x86_64/目录，但没有egg。我的系统上有一些MachOGraph.py个文件，但它们都没有。此目录下的任何内容都不包含字符串loader.filename。

发生了什么事？我怎样才能找到该文件？

为了完整性，这里是完整的追溯：

Answer 1

此问题是由 Pillow 引起的，您可以使用pip uninstall Pillow将其卸载，然后此问题就会消失。

Answer 2

Python在打印回溯时采用字节码中报告的文件名。在这种情况下，字节码包含生成的Python egg文件名，这种格式至少包含字节码文件。这些路径反映了构建目录时相对于包的构建目录。

在这种情况下，py2app installer包含macholib作为安装要求; setuptools下载source code for that library并按需生成一个鸡蛋，与py2app鸡蛋位于同一位置。我在/usr/local/src/Mnemosyne-2.3.1/py2app-0.8.1-py2.7.egg查看macholib-1.6-py2.7.egg目录。

Answer 3

使用 macholib1.7，来自** / MachOGraph.py的第46行......：

            try:
                fn = dyld_find(filename, env=self.env,
                    executable_path=self.executable_path,
                    loader=loader.filename)
                self.trans_table[(loader.filename, filename)] = fn
            except ValueError:
                return None

将第49行更改为：

                    loader_path=loader.filename)

Python回溯指向不存在的文件
