OSX+Eclipse+PyDev路径

Question

尝试使用Eclipse和PyDev让以下脚本在OSX上运行（Debug）：

#------------------------------------------------------
import os, subprocess
from os.path import join as join_path

def cmd(command):
    print('$ ' + command)

    process = subprocess.Popen(command, shell=True, executable="/bin/bash", stdin=None, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

    return process.communicate() + (process.returncode,)


stdout, stderr, error_code = cmd('echo $PATH')  
print(stdout, stderr, error_code)

stdout, stderr, error_code = cmd('echo $PYTHONPATH')  
print(stdout, stderr, error_code)

stdout, stderr, error_code = cmd('which python')  
print(stdout, stderr, error_code)

stdout, stderr, error_code = cmd('which apt-get')  
print(stdout, stderr, error_code)
#------------------------------------------------------

但是$PATH不是我在.bashrc或.profile中设置的，我不能运行apt get，它在sw/bin中。似乎我的$PATH在运行时被覆盖或设置不正确子流程.Popen. 在

以下是我从上述脚本中得到的输出：

Answer 1

PyDev可能独立于bash配置文件中的设置来设置$PATH。在

我建议你：

从具有正确路径设置的bashshell启动PyDev（我假设Eclipse将从shell继承环境）。在

或者

在Eclipse中显式地配置PATH（我不知道如何做的细节，请在文档中搜索“environment variables”）。在

好吧，找到了一个简单的问题解决方案。在这里找到了一些好的注释：Environment variables in Mac OS X

从一个终端启动Eclipse—尽管很烦人—工作很好。从我的终端类型/Applications/eclipse/eclipse和我的环境变量中获取：

$ echo $PATH ('/sw/bin:/sw/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/usr/local/mysql/bin:sw/bin:/usr/local/mysql/bin:sw/bin:/usr/X11R6/bin\n', '', 0) $ echo $PYTHONPATH ('/Applications/eclipse/plugins/org.python.pydev_2.6.0.2012062515/pysrc/pydev_sitecustomize:/Users/bryancdickson/Development/Lootsie/_repos/ap/ap:/Users/bryancdickson/Development/Lootsie/_repos/ap/ap/ap:/sw/bin:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python27.zip:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages:/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-old:/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload:/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC:/Library/Python/2.7/site-packages:/sw/bin\n', '', 0) $ which python ('/usr/bin/python\n', '', 0) $ which apt-get ('/sw/bin/apt-get\n', '', 0)

您可以在以下位置找到内部PyDev首选项：

在窗口：首选项:PyDev:解释器-Python

这包括系统PYTHONPATH。在
