从嵌入式python的zip加载pyd文件 [英] load pyd files from a zip from embedded python

问题描述

只有在将sys.path扩展为包括zip文件之后，才可以通过从Python解释器调用 import some_module
从zip文件中加载Python模块（.py，.pyc，.pyd）。 b $ b并且只有在我运行后

  import zipextimporter 
 zipextimporter.install（）
  

后者是.pyd模块所必需的。

我也可以从嵌入在C ++中的Python加载Python .py和.pyc模块。但是，为了也从嵌入式Python加载.pyd模块，我添加了

  PyRun_SimpleString（ import zipextimporter）; 
  

C ++ exe超出此行运行且没有错误。但是下一条命令

  PyRun_SimpleString（ zipextimporter.install（））; 
  

给我这个错误：

为什么zipextimporter.install（ ）在嵌入Python时崩溃？

我该如何解决？

也许与C ++代码
的编译方式有关吗？我使用g ++：

g ++ embed-simple.cpp -IE：\Python27\include -LE：\Python27\libs- lpython27 -o embed-simple

我看到了一个链接
如何使用mingw gcc与msvcr90.dll链接？

<可以提供解决方案吗？
如果是，我应该如何调整gcc-> g ++，因为我正在运行C ++代码，而不是C。

我正在运行Python 2.7。在WinXP上为2。

在全新安装Python 2.7.2之后，我没有得到运行时错误，只是这样：

导入错误：没有名为...的模块。

是否会影响方式嵌入的C ++脚本是否已编译？我用的是g ++。我也用英特尔编译器编译了
，但是给出了相同的运行时错误。也许我应该尝试MS Visual C ++。

还是使用ctypes导入pyd？

解决方案

memimporter和zipextimporter确实能够从内存/ zip归档文件中加载.pyd文件，而无需将它们解压缩到文件中。

runtimerror R6034是由于VC9运行时库必须通过清单加载。如果使用不同的C运行时在Python 2.5中运行代码，则很可能会成功。我猜您必须在自己的exe中嵌入一个引用VC9运行时库的清单。也许py2exe Wiki可以提供一些指导。

I can load Python modules (.py, .pyc, .pyd) from a zip file by calling "import some_module" from a Python interpreter only after sys.path has been extended to include the zip file and only after I have run

import zipextimporter
zipextimporter.install()

The latter is required for .pyd modules.

I can also load Python .py and .pyc modules from Python embedded in C++. However, in order to also load .pyd modules from embedded Python I added

PyRun_SimpleString("import zipextimporter");

The C++ exe runs beyond this line without error. But the next command

PyRun_SimpleString("zipextimporter.install()");

gives me this error:

Why does zipextimporter.install() crash when Python is embedded?

How can I solve this?

Does it perhaps have to do with the way the C++ code is compiled? I use g++:

g++ embed-simple.cpp -IE:\Python27\include -LE:\Python27\libs -lpython27 -o embed-simple

I saw a link How to link against msvcr90.dll with mingw gcc?

Could that provide a solution? If yes, how should I adjust it, gcc-->g++, since I am running C++ code, not C.

I am running Python 2.7.2 on WinXP.

I don't get the runtime error after a clean install of Python 2.7.2, just this:

Import Error: No module named....

Would it matter the way the embedding C++ script is compiled? I used g++. I also compiled with the Intel compiler, but that gave the same runtime error. Perhaps I should try MS Visual C++.

Or use ctypes to import the pyd?

解决方案

memimporter and zipextimporter are indeed able to load .pyd files from memory/zip-archives without unpacking them to files.

The runtimerror R6034 is caused by the fact that the VC9 runtime library must be loaded via a manifest. Running your code in Python 2.5, whic uses a different C runtime, would most probably succeed. I guess you must embed a manifest referencing the VC9 runtime library in your exe; maybe the py2exe wiki can provide some guidance.
