这是一个创建于 3650 天前的主题，其中的信息可能已经有所发展或是发生改变。
Gentoo Linux环境，今天突然发现很多python程序都不能用了：例如pip/equery/markdown2，还有其它众多python程序
重现问题：
在终端里直接输入pip或者equery或者markdown2，不用任何参数，就能看到相同的错误输出。
不知道是哪里出了问题。。。
执行`equery`时的错误输出如下：（执行pip/markdown2时结果一样，除了/usr/bin/xxx那几句）
Usage: /usr/bin/equery [-l <lexer> | -g] [-F <filter>[:<options>]] [-f <formatter>]
[-O <options>] [-P <option=value>] [-o <outfile>] [<infile>]
/usr/bin/equery -S <style> -f <formatter> [-a <arg>] [-O <options>] [-P <option=value>]
/usr/bin/equery -L [<which> ...]
/usr/bin/equery -N <filename>
/usr/bin/equery -H <type> <name>
/usr/bin/equery -h | -V
Highlight the input file and write the result to <outfile>.
If no input file is given, use stdin, if -o is not given, use stdout.
<lexer> is a lexer name (query all lexer names with -L). If -l is not
given, the lexer is guessed from the extension of the input file name
(this obviously doesn't work if the input is stdin). If -g is passed,
attempt to guess the lexer from the file contents, or pass through as
plain text if this fails (this can work for stdin).
Likewise, <formatter> is a formatter name, and will be guessed from
the extension of the output file name. If no output file is given,
the terminal formatter will be used by default.
With the -O option, you can give the lexer and formatter a comma-
separated list of options, e.g. ``-O bg=light,python=cool``.
The -P option adds lexer and formatter options like the -O option, but
you can only give one option per -P. That way, the option value may
contain commas and equals signs, which it can't with -O, e.g.
``-P "heading=Pygments, the Python highlighter".
With the -F option, you can add filters to the token stream, you can
give options in the same way as for -O after a colon (note: there must
not be spaces around the colon).
The -O, -P and -F options can be given multiple times.
With the -S option, print out style definitions for style <style>
for formatter <formatter>. The argument given by -a is formatter
dependent.
The -L option lists lexers, formatters, styles or filters -- set
`which` to the thing you want to list (e.g. "styles"), or omit it to
list everything.
The -N option guesses and prints out a lexer name based solely on
the given filename. It does not take input or highlight anything.
If no specific lexer can be determined "text" is returned.
The -H option prints detailed help for the object <name> of type <type>,
where <type> is one of "lexer", "formatter" or "filter".
The -h option prints this help.
The -V option prints the package version.

推测原因和“pygmetns”有关，
我在/usr/bin下把所有带“__requires__ = 'Pygments==1.6'”的程序随机抽取部分试了一下，都是这个相同的错误提示；
而没有 requires pygments的都没有这个错误。

这不是error log 这个是帮助信息。
pip list 会不会列出你的包列表？ 觉得是你把shell 编译坏了 |

abccba OP @scys 谢谢
pip之类的python程序已经完全没法用了 % pip list Error: cannot read infile: [Errno 2] No such file or directory: 'list' ~ % pip show Error: cannot read infile: [Errno 2] No such file or directory: 'show' |

你是不是喜欢在全局模式下pip安装东西? 我猜是你安装的类库不向下兼容， 系统的依赖被破坏了。

自己电脑？重新灌次gentoo没法判断你破坏了什么

输出的好像是某个包的帮助文档啊，可是竟然搜不出来是什么包。
你切换一下python版本试试： $ sudo eselect python list Available Python interpreters: [1] python2.7 * [2] python3.3 $ sudo eselect python set 2 |

哈哈，一下想起来，eselect你也是没法用的。在Gentoo下玩坏Python是很要命的呢。

不喜欢绕过portage装东西，不过上次好像是用pip装过啥，可惜现在查.zsh_history看不到了。 有办法吧pip安装的都删掉么，没有用pip安装过非常重要的包，强制删掉应该没问题吧。 |

emerge 还能用吗？
至于pip， $ pip list $ pip uninstall <package> |

灌gentoo 不需要吧？要不换arch 好了

emerge还能用 % pip list Error: cannot read infile: [Errno 2] No such file or directory: 'list' 强烈推测为“pygmetns”的原因， 我在/usr/bin下把所有带“__requires__ = 'Pygments==1.6'”的程序都试了一下，都是这个错误； 而没有 requires pygments的都没有这个错误。 |

你说对了，这些错误提示和帮助信息，还真是pygments (pygmentize命令)

推测 Pygments版本过高，可以的话执行pip freeze|grep Pygments 看看是否高于1.6
如果是这样，应该卸载Pygments，重新安装1.6版本的 Pygments。 一点点建议：1. Linux python 开发环境 应与系统默认 python 环境区分开 2. 使用pythonenv 管理自己的开发环境 3.系统环境包除非你知道自己在做什么否则别动它，自己的环境多备份以便深度折腾。 :) |

我也遇到了类似的问题，但 pip 可以用，emerge 不能用了～～～
