为PyDev安装Jython时出错

标签： python eclipse jython pydev

我以前在eclipse中安装了PyDev和Jython，但我从未遇到过问题。但是这次我在手动或自动安装时遇到错误：

Unable to gather the needed info from the system.

This usually means that your interpreter is not in
the system PATH.
No output was in the standard output when trying to create the interpreter info.
The error output contains:>>Traceback (innermost last):
  File "/home/michaele/Downloads/eclipse/plugins/org.python.pydev_2.5.0.2012040618/PySrc/interpreterInfo.py", line 89, in ?

在命令行上使用Jython或Python运行相同的脚本似乎很好：

也可以使用Python或Jython从eclipse中的交互式控制台运行，即：

的Python：

import sys; print('%s %s' % (sys.executable or sys.platform, sys.version))
/usr/bin/python2.6 2.6.6 (r266:84292, Sep 15 2010, 16:22:56) 
[GCC 4.4.5]
PyDev console: using default backend (IPython not available).
import os
os.path.normpath('/')
'/'

的Jython：

import sys; print('%s %s' % (sys.executable or sys.platform, sys.version))
--->  reloading /eclipse/plugins/org.python.pydev_2.5.0.2012040618/PySrc/pydevconsole.py
PyDev console: using default backend (IPython not available).

You are now in a console within Eclipse.
Use it with care as it can halt the VM.
Typing a line with "PYDEV_CONSOLE_TOGGLE_RUN_IN_UI"
will start executing all the commands in the UI thread.

java1.6.0_21 2.2.1
import os
os.path.normpath('/')
'/'

环境信息：

OS- Ubuntu 10.10 Maverick

Eclipse- Version: Indigo Service Release 2
         Build id: 20120216-1857

Python- 2.6.6

Jython- 2.2.1 on java1.6.0_21

Java- java version "1.6.0_21"
      Java(TM) SE Runtime Environment (build 1.6.0_21-b06)
      Java HotSpot(TM) 64-Bit Server VM (build 17.0-b16, mixed mode)

很抱歉这篇长篇文章，但我不知道有什么相关内容。我已经尝试了一切我能想到的让Jython在PyDev中工作无济于事。任何帮助将不胜感激。

谢谢，

麦克

感谢我提供帮助的所有建议。但是不要再去了。

我在尝试将一个Jython解释器添加到eclipse时遇到了一个类似的问题，即获取“从解释器获取信息时出错”消息。在我的情况下，我使用的是我自己构建的Jython版本。

当你在根jython目录中运行ant build（没有选项）时，它将产生dist / jython-dev.jar。这个jar文件如果不同于你从jython网站下载的jar文件，它不会捆绑jython需要的所有第三方jar。 ant生成的dist / bin / jython脚本将这些脚本添加到类路径中。

Pydev不使用该脚本来运行Jython，它只是使用jar文件并假设它包含所需的一切。为了获得解释器信息，Pydev运行如下命令：

/System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/java -Dpython.home=/Users/me/dev/projects/jython/dist -classpath /Users/me/dev/projects/jython/dist/jython-dev.jar org.python.util.jython /Users/me/dev/projects/Pydev/plugins/org.python.pydev/pysrc/interpreterInfo.py

您可以通过在jython根文件夹中运行以下内容来编译捆绑所有需求的jython.jar文件：

ant jar-complete

这会将jython.jar放入dist文件夹，该文件夹可以与Pydev一起使用。

必须说我之前从未见过那个：）

我能想象的一些事情可以解决它：

  1. 尝试更改：

    \插件\ org.python.pydev_2.5.0.2012040618 \ PySrc \ interpreterInfo.py

    变化：

    导入os

    为：

    import os.path

  2. 另一个猜测是，在Eclipse内部时，某些环境变量是不同的...首先要检查的是从您执行这些打印的同一个控制台启动Eclipse（而不是直接从桌面启动它 - 如果就是这样）。

  3. 如果仍然无效，请执行以下操作：

    在interpreterInfo.py脚本的开头（在“import os”之后）

    做：

    print（'\ n'.join（在os.environ.items（）中排序（str（x）for x）））

    然后尝试配置解释器并在帖子中发布该日志。然后，也从控制台运行interpreterInfo.py并将其添加到帖子中（以查看环境是否有任何差异）。
