pip freeze省略了某些包

Question

At the moment, I have python-qt4 (binary packages) installed on my Ubuntu 12.10 through Ubuntu's repository. If I run aptitude show python-qt4 , the result would be:

Package: python-qt4
State: installed
Automatically installed: no
...

However if I run pip freeze , I can't find PyQt nor PyQt4 entry from the output. Does pip omit certain packages from its freeze command? What is the cause of the problem?

Answer 1

你的python-qt4软件包没有.egg-info元数据文件，所以pip不可能知道它已安装。
