我正在使用 CentOS6 Bash 并尝试使用 Python 和 cx_Freeze。我不熟悉 PATH 和 Path 修改，这是服务器，我有点担心自己尝试（但我必须这样做）。当我尝试 $cx_f/Freeze 时，我得到-bash: cx_Freeze: command not found- 任何 cx_Freeze setup.py 等...尝试（包括module not found）也是如此。我的目标是使用 cx_freeze（一个 Python 捆绑工具）。Bash 的 o/p 如下。
$ which python
/usr/bin/python
$ sudo locate -b python | fgrep -w bin
[sudo] password for xyz:
/usr/bin/abrt-action-analyze-python
/usr/bin/pip-python
/usr/bin/python
/usr/bin/python-config
/usr/bin/python-pip
/usr/bin/python2
/usr/bin/python2.6
/usr/bin/python2.6-config
/usr/local/cpanel/3rdparty/bin/python
/usr/local/cpanel/bin/ispythonversion2
/usr/local/cpanel/bin/ispythonversion2inbin
cx_Freeze 显然位于 /usr/lib/Python2.6/site-packages 由这个 o/p 证明
[xyz@server ~]$ ls
cpu perl5 usr xyz
[xyz@server ~]$ cd usr
[xyz@server usr]$ cd lib
[xyz@server lib]$ ls
python2.6
[xyz@server lib]$ cd python2.6
[xyz@server python2.6]$ ls
site-packages
[xyz@server python2.6]$ cd site-packages
[xyz@server site-packages]$ ls
cx_Freeze cx_Freeze-4.3.1-py2.6.egg-info
[xyz@server site-packages]$ cd cx_Freeze
[xyz@server cx_Freeze]$ ls
bases finder.py freezer.pyc hooks.pyo initscripts main.py setupwriter.py windist.py
dist.py finder.pyc freezer.pyo __init__.py macdist.py main.pyc setupwriter.pyc windist.pyc
dist.pyc finder.pyo hooks.py __init__.pyc macdist.pyc main.pyo setupwriter.pyo windist.pyo
dist.pyo freezer.py hooks.pyc __init__.pyo macdist.pyo samples util.so
然后，再一次：
[xyz@server ~]$ ls
cpu cpu.py perl5 usr xyz
[xyz@server ~]$ cd usr
[xyz@server usr]$ ls
bin lib share
[xyz@server usr]$ cd bin
[xyz@server bin]$ ls
cxfreeze cxfreeze-quickstart
[xyz@server bin]$ cxfreeze-quickstart
-bash: cxfreeze-quickstart: command not found
所以，这让我对 cx_Freeze 安装的位置更加困惑！让事情变得更糟，正如 BM 所说：“但等等，还有更多！”
[xyzserver ~]$ sudo locate -b site-packages
[sudo] password for xyz:
/usr/lib/python2.6/site-packages
/usr/lib64/python2.6/site-packages
/usr/share/xemacs/site-packages
为什么有这么多网站包。/lib/ 和 /lib64/ 中的内容不同，/lib/ 中的内容包含我需要的内容——尽管两者都没有 cx_Freeze。
（我已经从上面的示例中删除了 Python，site-packages 结果，它对应于我创建的 virtualenv，因为它是我理解的并且可能会使事情复杂化。）
