在 Debian 测试中使用旧的？Python3 模块安装 Cantera 以运行 SCons 脚本时遇到问题

如何解决在 Debian 测试中使用旧的？Python3 模块安装 Cantera 以运行 SCons 脚本时遇到问题

更新

这是 cantera 的链接：enter link description here 我确实安装了 scons；

 apt-cache policy scons*
  scons:
 Installed: 4.0.1+dfsg-2
 Candidate: 4.0.1+dfsg-2
 Version table:
 *** 4.0.1+dfsg-2 900
    900 http://deb.debian.org/debian testing/main amd64 Packages
    100 /var/lib/dpkg/status
     3.0.1-2 500
    500 http://http.us.debian.org/debian stable/main amd64 Packages

这里是一个调用安装脚本的例子；

scons build prefix='/home/X/SW/Cantera/installed/' --config=force

---

我一直在尝试升级/安装 Cantera (cantera.org)，它依赖于 Scons（使用了脚本“SConstruct”）。我注意到脚本中有一行，from buildutils import *。我尝试使用 python3 -m pip install --user buildutils 安装它，但出现了一个大错误：

我看到“版本冲突”和括号问题....我还注意到最新版本是 2007 年的...https://pypi.org/project/buildutils/ 是否有更新的替代版本？

我想尝试从源代码手动安装它（egg 文件显然是为 python2 构建的），但无法成功执行 ez_setup.py 或 setup.py 而没有错误。我关注了一页，但在不确定发生了什么之前从未这样做过。

我在互联网上看到很多关于找不到模块的请求，但大多数答案都围绕着错误命名 (Can't install PyZMP for Python -- Dependencies) 或未安装。

我从 Debian 存储库中搜索了与 buildutils 相关的内容，但没有找到相关内容。

这源于我从 scons 脚本中得到的关于 keyvalue 的错误，此处显示了相关部分：

...
...

  File "/home/X/.local/lib/python3.9/site-packages/SCons/Environment.py",line 388:
    return self._dict[key]

所以脚本 SConstruct 的 1543 行是；

...

1534     if env.get(configvar) == comp:
1535         configh[definevar] = value
1536     else:
1537         configh[definevar] = None
1538
1539 # Need to test all of these to see what platform.system() returns
1540 configh['SOLARIS'] = 1 if env['OS'] == 'Solaris' else None
1541 configh['DARWIN'] = 1 if env['OS'] == 'Darwin' else None
1542
1543 if env['OS'] == 'Solaris' or env['HAS_CLANG']:
1544     configh['NEEDS_GENERIC_TEMPL_STATIC_DECL'] = 1
1545
1546 configh['CT_SUNDIALS_VERSION'] = env['sundials_version'].replace('.','')
1547
1548 if env.get('has_sundials_lapack') and env['use_lapack']:
1549     configh['CT_SUNDIALS_USE_LAPACK'] = 1
1550 else:
1551     configh['CT_SUNDIALS_USE_LAPACK'] = 0
1552
1553 cdefine('LAPACK_FTN_STRING_LEN_AT_END','lapack_ftn_string_len_at_end')

这看起来只是一本字典，即这里的快速入门部分：enter link description here 但我在目录 (def Environment) 所以我认为它可能是这个模块 grep -nRHI "def Environment" * 的一部分。这然后解释了为什么我尝试安装它以及随后的错误。我意识到我可以尝试只注释掉第 1543 行和取消缩进第 1544 行，因为我确实有叮当声，但我不确定我是否有“正确”的叮当声...

编辑

我确实有 buildutils，并搜索 PyPl，也许这是替代品.... buildutil 的 mercurial 存储库链接似乎不起作用，但也许我可以只 {{1 }} 替换整个项目中的名称...我也在 https://pypi.org/project/buildutil/ 上看到它可能只对 python3.6 有用...

编辑 2

我现在想知道它是否不仅仅是重命名...，因为这两个名称都列在 https://github.com/tedicreations/buildutil 上...所以也许只是 buildutils 脚本将名称从 {{1 }} 到 awk...

编辑 3 根据 awk 的建议，我尝试了这些更改；

buildutils

但是在 buildutil 和 2to3 之后，错误仍然存​​在（可能是字典问题...）；

还有……

这是来自 2to3 模块，因为它没有摆脱 buildutils（我没有），尝试运行它似乎毫无意义......我做到了...还是一样的错误。

buildutil

解决方法

一些旧包可以用 2to3 tool 修复，在旧源文件夹上运行它，然后尝试用 python3 设置。另一种方式是安装python2。
