Python追溯指向不存在的文件

Question

我正在嘗試運行setup.py腳本（用於mnemosyne ）。 該腳本失敗，如果只能找到要編輯的文件，我敢肯定我知道如何解決該問題。 問題是回溯指向不存在的文件：

  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'

我相信應該是loader_path 。 問題是MachOGraph.py文件不存在-在我當前路徑或anaconda發行版中都沒有。 有一個build/bdist.macosx-10.5-x86_64/目錄，但是沒有egg 。 我的系統上有一些MachOGraph.py文件，但是沒有一個文件顯示該行。 此目錄下的任何內容都不包含字符串loader.filename 。

這是怎么回事？ 如何找到該文件？

為了完整起見，這是完整的回溯：

Answer 1

此問題是由Pillow引起的，您可以使用pip uninstall Pillow進行卸載，然后此問題將消失。

Answer 2

打印回溯時，Python會采用字節碼中報告的文件名。 在這種情況下，字節碼包含為生成Python egg而生成的文件名，該格式至少包含字節碼文件。 這些路徑反映了相對於軟件包構建時的構建目錄。

在這種情況下， py2app安裝程序包括macholib作為安裝要求； setuptools下載該庫的源代碼，並根據需要在與py2app egg相同的位置生成一個egg。 我會在/usr/local/src/Mnemosyne-2.3.1/py2app-0.8.1-py2.7.egg查找macholib-1.6-py2.7.egg目錄。

Answer 3

使用macholib1.7，從** / MachOGraph.py ...的第46行開始：

            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

將第49行更改為：

                    loader_path=loader.filename)
