这是PATH没有sudo 的变量:

$ echo 'echo $PATH' | sh 
/opt/local/ruby/bin:/usr/bin:/bin

这是PATHsudo 的变量:

$ echo 'echo $PATH' | sudo sh
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

据我所知,sudo应该PATH保持不变.这是怎么回事？我该如何改变？(这是在Ubuntu 8.04上).

更新:据我所知,没有任何脚本PATH以任何方式作为root更改.

来自man sudo:

为了防止命令欺骗,当在用户的PATH中搜索命令时(如果一个或两个都在PATH中),sudo会检查``.''和``''(都表示当前目录).但请注意,实际的PATH环境变量未被修改,并且不会更改地传递给sudo执行的程序.

当我尝试以任何方式使用pip时,我遇到了问题.我正在使用Ubuntu 16.04.4

我应该说我已经使用过了,我从来没有遇到过任何问题,但是从今天开始,当我使用任何命令时,我总会得到相同的错误(例如使用pip --upgrade).

Traceback (most recent call last):
  File "/usr/local/bin/pip", line 7, in <module>
    from pip._internal import main
ImportError: No module named _internal

我尝试过sudo apt-get remove python-pip后续sudo apt-get install python-pip但没有改变.

感谢您的时间!

pip install <package name>对我而言,每个包都失败了.这就是我得到的:

Could not find a version that satisfies the requirement <package-name
(from versions: )
No matching distribution found for <package-name>

我在Stack Overflow上看到了 类似的 问题,但它们似乎与这个问题没有完全相关.

此外,这篇文章表明,如果PyPI关闭或我的IP地址被列入黑名单,可能会发生这种情况.对我来说,这似乎都不正确.

pip显示最新的运行情况pip install --upgrade pip.

我的控制台:

desarrollador @ desarrollador-HP-14-Notebook-PC1:〜$ pip freeze
Exception:

我安装了龙卷风包,从那以后就发生了.我该如何解决？

我通过以下命令安装了弹性搜索策展人.

sudo pip install -U elasticsearch-curator

这一切都安装好了.

但是现在当我做以下事情时

curator_cli --version

我得到以下依赖警告.

 /usr/local/lib/python2.7/dist-packages/requests/__init__.py:83: RequestsDependencyWarning: Old version of cryptography ([1, 2, 3]) may cause slowdown.
  warnings.warn(warning, RequestsDependencyWarning)
curator_cli, version 5.5.4

如何修复警告或隐藏警告？

我正在尝试安装 jupyterthemes 包并收到此错误。

我早先在我的OSX上安装了pip,但它不能以某种方式工作.所以,我试图再次使用命令安装pip:

sudo easy_install pip

但它给我的错误如下:

pip 9.0.1 is already the active version in easy-install.pth
Installing pip script to /usr/local/bin
error: [Errno 2] No such file or directory: '/usr/local/bin/pip'

我既不能使用pip,也不能安装它.
