Question

我安装了以下版本的numpy：

sh-3.2# pip --version
pip 1.5.4 from /usr/local/lib/python2.7/site-packages (python 2.7)

sh-3.2# pip list
...
numpy (1.7.1)
...

sh-3.2# pip install --upgrade --ignore-installed numpy
Downloading/unpacking numpy
  Downloading numpy-1.8.0.tar.gz (3.8MB): 3.8MB downloaded
  Running setup.py (path:/private/tmp/pip_build_root/numpy/setup.py) egg_info for package numpy
    Running from numpy source directory.

...installing stuff..

Successfully installed numpy
Cleaning up...
sh-3.2# pip list
...
numpy (1.7.1)
...

如您所见：没有升级。那怎么样？

更新：完成安装过程的输出：http://pastebin.com/wki2JNyh

Update2：实际上我认为路径应该没问题：

Answer 1

您的pip命令显示来自/usr/local/lib/python2.7的python，在安装过程中/usr/local/Cellar/python/2.7.5/

是符号链接还是其他路径？

Answer 2

好的，问题是以某种方式保留了旧包。因此，我只是进入了directoy并删除了相应的包。

这是我做的：

sh-3.2# pip list | grep numpy
numpy (1.7.1)
sh-3.2# pwd
/usr/local/lib/python2.7/site-packages
sh-3.2# rm numpy*
sh-3.2# pip install numpy
sh-3.2# pip list | grep numpy
numpy (1.8.0)

现在它运作正常！

pip不升级包
