python - 在 Lubuntu 14.04 上安装 Python3.4.3 时出现错误/测试失败

Question

我使用 VMplayer，我的操作系统是 Lubuntu 14.04。它预装了python3.4.0，但我想安装python3.4.3。我从 here 下载了 .tar.xz 文件.

然后我提取文件并按照自述文件中的说明进行操作:

./configure
make
make test

当我第一次运行时

make test

它说“3 次测试失败，3 次更改执行环境，25 次跳过”。我在这里发布了关于 SO 的问题: Installing Python3.4.3: 3 tests failed, 3 altered execution environment and 25 skipped

然后我做了

sudo apt-get install libssl-dev

做了

./configure
make

再次，它说:

Python build finished successfully!
The necessary bits to build these optional modules were not found:
_bz2                  _curses               _curses_panel      
_dbm                  _gdbm                 _lzma              
_sqlite3              _tkinter              readline           
To find the necessary bits, look in setup.py in detect_modules() for the module's name.

当我尝试的时候

make test

它说

1 test failed:
    test_ssl
2 tests altered the execution environment:
    test___all__ test_warnings
21 tests skipped:
    test_bz2 test_curses test_dbm_gnu test_dbm_ndbm test_devpoll

中间的代码有点多，但我删除了它，因为它会超过 body 限制。尽管如此，最主要的是，1 个测试失败，2 个测试改变了执行环境，21 个测试被跳过。

即使我按照 the Python downloads page 上的确切步骤操作，我也知道为什么我会失败并跳过测试？有没有更简单的方法在我的操作系统上安装 Python3.4.3？

解决 OP 问题

从测试来看，Python 构建正常。 “Python build finished successfully!” 缺少的模块在那里，因为您的计算机上没有安装相关软件。

这与使用 apt-get 没有什么不同，例如您缺少 _tkinter 这是因为您没有运行它所需的包。因此，如果您使用的是 apt-get，则必须使用 apt-get install python-tk 以便 apt-get 能够引入相关依赖。逻辑是，如果您没有安装软件，您将不需要模块来对其进行编程。

我在 make tests 中看到的唯一问题是 ssl 失败。

1 test failed:
    test_ssl

查看测试结果你会看到:-

test_ssl: testing with 'OpenSSL 1.0.1f 6 Jan 2014' (1, 0, 1, 6, 15)
      under Linux ('debian', 'jessie/sid', '')
      HAS_SNI = True
      OP_ALL = 0x-7ffffc01
      OP_NO_TLSv1_1 = 0x10000000

此版本的 OpenSSL 包含去年发现并在 OpenSSL 1.0.1j [2014 年 10 月 15 日] 中修复的 SSL 协议(protocol)漏洞。您可以找到此信息 here .

我不太喜欢 Ubuntu，因为我使用的是 Fedora，但你可以试试 :-

apt-get update
apt-get dist-upgrade

看看这是否修复了您的计算机存在的 SSL 漏洞。

从源安装

附带说明一下，如果您希望为您使用的系统以外的系统开发 Python 应用程序，那么从源代码安装是唯一的选择。

从 tar.gz 编译有很多很好的理由。

1. 大多数 Linux 发行版在内部使用 Python，因此链接到一个版本。

2. 导入的模块之间可能会发生冲突。

3. 您可以针对不同版本的 python 测试您的代码。

4. 您不需要 root 权限来设置您自己的版本，因此您的操作独立于操作系统所需的任何内容。

所以在这个例子中，我的家是 /home/paul 并且我已经在我家的根目录中创建了目录。一个名为 src 的目录将用作源目录，另一个名为 opt 的目录将保存我的 Python 版本。

诀窍是告诉 Python 安装要去哪里。所以将tar.gz文件放到src目录下，展开。打开终端并...

cd ~/src/Python-X.X.X
./configure --prefix=/home/paul/opt/python.x.x.x
make
make test <optional>
make install 

请注意，我从来没有使用过 sudo，因为我有权访问我的主目录，而且我不会影响系统上的任何其他内容。

现在测试...

~/opt/python.3.4.2/bin/python3
Python 3.4.2 (default, Mar 28 2015, 19:36:24) 
[GCC 4.9.2 20150212 (Red Hat 4.9.2-6)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 

您可以在新版本出现时继续添加测试版本，只需记住通过指向您要使用的版本来开始您的代码。
