sudo: pip: command not found in CentOS
提问by zimmer
I use CentOS and I installed pip to /usr/local/python-dir/bin/pip. I made a link to /usr/local/bin/pip. Then I executed sudo pip install xxx, it reported an error like this:
我使用 CentOS 并将 pip 安装到/usr/local/python-dir/bin/pip. 我做了一个链接到/usr/local/bin/pip. 然后我执行了sudo pip install xxx，它报了这样的错误：
sudo: pip: command not found
I see $PATHis all right:
我看没问题$PATH：
/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin
However, I can only execute pip this way:
但是，我只能以这种方式执行 pip：
sudo /usr/local/bin/pip install xxx
How can I configure PATH or something else? Thanks a lot.
如何配置 PATH 或其他东西？非常感谢。

For security reasons, sudodoes not rely on the $PATHset in your environment. There is a secure_pathoption in /etc/sudoersthat specifies the PATHthat sudowill use for locating binaries. For example:
出于安全原因，sudo不依赖$PATH于您的环境中的设置。有一个secure_path在选项/etc/sudoers指定PATH是sudo将用于定位二进制文件。例如：
Defaults secure_path = /sbin:/bin:/usr/sbin:/usr/bin
Just add /usr/local/binto this PATH, or get used to typing:
只需添加/usr/local/bin到此 PATH，或者习惯键入：
sudo `which pip` install xxx

Try sudo bash -c 'echo $PATH'to see where sudois looking for commands; you can then symlink pipinto one of those directories.
尝试sudo bash -c 'echo $PATH'查看在哪里sudo寻找命令；然后，您可以符号链接pip到这些目录之一。

Not ideal but works. You can always unlink it after the install to restore security.
不理想但有效。您始终可以在安装后取消链接以恢复安全性。
sudo ln -s /usr/local/bin/pip /bin/pip
Puts pip in the root path bin. You can then run pip as sudo.
将 pip 放在根路径 bin 中。然后，您可以以 sudo 身份运行 pip。
