Jython-javaos.getenv()给出“无法获取环境，环境将为空". [英] Jython - javaos.getenv() gives "Failed to get environment, environ will be empty"

问题描述

每当我在Eclipse中运行任何jython程序时，在输出的开头都会出现以下错误:

Whenever I run any jython program in Eclipse, I got the following error in the beginning of the output:

"失败 得到环境，环境将会 空:(0，'执行命令失败 ([\'sh \'，\'-c \'，\'env \']): java.io.IOException:无法运行 程序"sh":Crea teProcess error = 2， 系统找不到文件 指定")

" Failed to get environment, environ will be empty: (0, 'Failed to execute command ([\'sh\', \'-c\', \'env\']): java.io.IOException: Cannot run program "sh": Crea teProcess error=2, The system cannot find the file specified')

首先，我的环境是:

Windows 2008

Windows 2008

JDK 1.6.0u10

JDK 1.6.0u10

jython 2.2.1

jython 2.2.1

我做了一些挖掘，然后才意识到此消息是在函数javaos.getenv()中产生的. 每当我调用javaos.getenv()函数时，它都会引发以下错误:

I did some digging, and I realized that this message is produced in the function javaos.getenv(). Whenever I call the javaos.getenv() function, it throws the following error:

C:\ jython2.2.1> java -jar jython.jar

C:\jython2.2.1>java -jar jython.jar

导入javaos

import javaos

打印javaos.getenv("user.name")

print javaos.getenv("user.name")

无法获取环境，环境 将为空:(0，'执行失败 命令([\'sh \'，\'-c \'，\'env \']): java.io.IOException:无法运行 程序"sh":Crea teProcess error = 2， 系统找不到文件 指定")

Failed to get environment, environ will be empty: (0, 'Failed to execute command ([\'sh\', \'-c\', \'env\']): java.io.IOException: Cannot run program "sh": Crea teProcess error=2, The system cannot find the file specified')

这很奇怪，因为我当前使用的是Windows计算机，而不是Unix.

This is strange, because I'm currently using a Windows machine, not an Unix.

推荐答案

尝试取消注释并更改注册表"文件中的os设置

Try to uncomment and change the os setting in the 'registry' file

(与您的jython.jar位于同一目录，我希望如此)

(it is in the same directory as your jython.jar / i hope)

# python.os determines operating-specific features, similar to and overriding the
# Java property "os.name".
# Some generic values are also supported: 'nt', 'ce' and 'posix'.
# Uncomment the following line for the most generic OS behavior available.
#python.os=None
python.os=nt
# try nt or dos
