Question

我创建了两个分别包含foo / comp1.py和foo / comp2.py的轮子。＆＃39;富＆＃39;是命名空间包（PEP420）。当在同一个文件夹中安装这两个软件包时，我希望pip能够合并它们。但它失败了。这是预期的吗？为什么呢？

示例：

pip_namespace>unzip -l comp1/dist/foo.comp1-1.0.0-py3-none-any.whl
Archive:  comp1/dist/foo.comp1-1.0.0-py3-none-any.whl
  Length      Date    Time    Name

pip_namespace>pip install -t test_pip comp1/dist/foo.comp1-1.0.0-py3-none-any.whl

Successfully installed foo.comp1
You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

pip_namespace>pip install -t test_pip comp2/dist/foo.comp2-1.0.0-py3-none-any.whl
Processing ./comp2/dist/foo.comp2-1.0.0-py3-none-any.whl
Installing collected packages: foo.comp2
Successfully installed foo.comp2
Target directory /remote/devsup/users/flemaitre/tmp/pip_namespace/test_pip/foo already exists. Specify --upgrade to force replacement.
You are using pip version 7.1.2, however version 8.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

因此缺少comp2：

pip_namespace>find test_pip/foo
test_pip/foo
test_pip/foo/__pycache__
test_pip/foo/__pycache__/comp1.cpython-35.pyc
test_pip/foo/comp1.py
