让pip下载更喜欢下载源代码分发(不是轮子)

Question

这个问题解释了如何制作pip下载和保存包.如果我遵循这个公式,Pip将下载wheel(.whl)文件(如果可用).

(venv) [user@host glances]$ pip download -d wheelhouse -r build_requirements.txt
Collecting wheel (from -r build_requirements.txt (line 1))
  File was already downloaded /usr_data/tmp/glances/wheelhouse/wheel-0.29.0-py2.py3-none-any.whl
Collecting pex (from -r build_requirements.txt (line 2))
  File was already downloaded /usr_data/tmp/glances/wheelhouse/pex-1.1.18-py2.py3-none-any.whl
Collecting requests (from -r build_requirements.txt (line 3))
  File was already downloaded /usr_data/tmp/glances/wheelhouse/requests-2.12.4-py2.py3-none-any.whl
Collecting pip (from -r build_requirements.txt (line 4))
  File was already downloaded /usr_data/tmp/glances/wheelhouse/pip-9.0.1-py2.py3-none-any.whl
Collecting setuptools (from -r build_requirements.txt (line 5))
  File was already downloaded /usr_data/tmp/glances/wheelhouse/setuptools-32.3.1-py2.py3-none-any.whl
Successfully downloaded wheel pex requests pip setuptools

它下载的每个文件都是一个Wheel - 但如果我想获得另一种文件怎么办？

我实际上想要下载sdist(.tar.gz)文件而不是.whl文件？有没有办法告诉Pip我真正希望它得到什么类型的文件？因此,我可能想要一堆tar.gz文件,而不是获得一个充满轮子的目录.

Answer 1

根据pip install -h:

--no-use-wheel在搜索索引和查找链接位置时,不要查找并更喜欢轮存档.弃用了--no-binary.

和

--no-binary不要使用二进制包.可以多次提供,每次都会增加现有值.接受:all:禁用所有二进制包,:none:清空集合或一个或多个包

pip install -U pip如果您的版本太旧,您可能需要升级pip .

Answer 2

用 pip download --no-binary=:all: -r requirements.txt

根据 pip 文档：

--无二进制：

不要使用二进制包。可以多次提供，每次都会增加现有值。接受 :all: 禁用所有二进制包， :none: 清空集合，或者一个或多个包名称之间用逗号分隔。请注意，某些软件包编译起来很棘手，并且在对它们使用此选项时可能无法安装。

它对我有用！
