点冻结不显示所有已安装的软件包 [英] pip freeze does not show all installed packages

问题描述

我正在使用virtualenv.我已安装fabric和pip.但是pip freeze对此没有任何提示.包在我的virtualenv中，但是pip对此保持沉默.为什么会这样呢?有什么方法可以调试吗?

I am using a virtualenv. I have fabric installed, with pip. But a pip freeze does not give any hint about that. The package is there, in my virtualenv, but pip is silent about it. Why could that be? Any way to debug this?

推荐答案

我自己尝试过此操作:

在"env"目录中创建一个virtualenv:

create a virtualenv in to the "env" directory:

$virtualenv2.7 --distribute env
New python executable in env/bin/python
Installing distribute....done.
Installing pip................done.

下一步，激活虚拟环境:

next, activate the virtual environment:

$source env/bin/activate

提示更改.现在安装结构:

the prompt changed. now install fabric:

(env)$pip install fabric
Downloading/unpacking fabric
  Downloading Fabric-1.6.1.tar.gz (216Kb): 216Kb downloaded
  Running setup.py egg_info for package fabric   
...

Successfully installed fabric paramiko pycrypto
Cleaning up...

pip freeze显示正确的结果:

(env)$pip freeze
Fabric==1.6.1
distribute==0.6.27
paramiko==1.10.1
pycrypto==2.6
wsgiref==0.1.2

也许您忘了激活虚拟环境?在* nix控制台上，键入which pip进行查找.

Maybe you forgot to activate the virtual environment? On a *nix console type which pip to find out.
