用旧安装Cantera的麻烦(？)Python3模块对Debian进行测试以运行SCons脚本

Question

更新

这是到cantera的链接：在这里输入链接描述和我确实安装了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

与消息来源的直接联系：

在这里输入链接描述

下面是一个调用安装脚本的示例；

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 (脚本'SConstruct‘是使用的)。我注意到脚本中有一行，from buildutils import *。我试着使用python3 -m pip install --user buildutils安装它，但是我得到了一个大错误：

我看到“版本冲突”和一个括号的问题..。我还注意到最新的版本是2007年发布的.https://pypi.org/project/buildutils/是否有一个更新的替代版本？

我想尝试从源代码手动安装它(很明显，鸡蛋文件是为python2构建的)，但是没有错误就无法成功地执行ez_setup.py或setup.py。我只看了一页，但从来没有做过，我不知道发生了什么。

我在互联网上看到很多关于模块找不到的请求，但是大多数的答案都是关于错误命名它(无法为Python安装PyZMP --依赖项)，或者它没有安装。

我从Debian中寻找一些与buildutils相关的信息，但是没有出现任何相关的信息。

这源于我从scon脚本中得到的关于KeyValue的一个错误，这里的相关部分显示：

...

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

因此，1543年左右的脚本SConstruct的行是；

...

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')

这看起来很像字典，即快速启动部分：在这里输入链接描述，但是我在目录(grep -nRHI "def Environment" *)的脚本中找不到一个def Environment (可能也是这个配置)，所以我假设它可能是这个模块buildutils的一部分。这就解释了为什么我试图安装它和随后的错误。我知道我可以试着评论第1543行和第1544行，因为我确实有声音，但我不确定我是否有“正确”的响声.

编辑

我有buildutil，搜索PyPl，也许这是替代.用于buildutils的mercurial存储库链接似乎不起作用，但也许我可以通过awk替换整个项目的名称.我还在https://pypi.org/project/buildutil/上看到，它可能只对python3.6有好处.

编辑2

我现在想知道这是否只是一个重命名.，因为这两个名字都列在https://github.com/tedicreations/buildutil上.所以也许只是awk脚本把名字从buildutils改为buildutil.

编辑3根据2to3的建议，我尝试了用这些变化显示；

我注意到，2to3的规则可能无法将模块从buildutils转换为buildutil，如果这确实是一个适当的更改.

还有..。

这是来自modernize模块，因为它没有摆脱buildutils (我没有)，尝试运行它似乎毫无意义.我做了..。还是同样的错误。

Answer 1

一些旧包可以用2至3工具修复，在旧的源文件夹上运行，然后尝试使用python3进行安装。另一种方法是安装python2。
