为什么我不能使用--target和--editable来调用pip?

问题描述

我正在使用

pip install --target deploy_directory.

pip install --target deploy_directory .

准备要在Google App Engine上部署的软件包，但要在dev_appserver.py下进行测试，我想在开发模式下安装该软件包(即，使用"--editable").但是，当我尝试:

to prepare packages for deployment on Google App Engine, but for testing under dev_appserver.py, I would like to install the package in development mode (i.e., with '--editable'). However, when I try:

pip install --target deploy_directory --editable.

pip install --target deploy_directory --editable .

我得到类似的东西:

Complete output from command /my/venv/bin/python -c "import setuptools, tokenize;__file__='/Path/To/MyPackage/setup.py';exec(compile(getattr(tokenize, 'open', open)(__file__).read().replace('\r\n', '\n'), __file__, 'exec'))" develop --no-deps --home=/var/folders/5h/k2xt_l014s1c1gvmnssm963c0000gp/T/tmpoml8u3:

   or: -c --help [cmd1 cmd2 ...]
   or: -c --help-commands
   or: -c cmd --help

error: option --home not recognized

这似乎是因为"setup.py开发"不接受"--home"而引起的.

Which seems to happen because 'setup.py develop' doesn't accept '--home'.

这是我的setup.py:

Here's my setup.py:

 from setuptools import setup, find_packages
 import os
 import sys
 from codecs import open

  setup(name="MyModule",
        version="0.1.0",
        long_description="Blah blah",
        author="Me",
        packages = find_packages()
  )

如何轻松处理在开发服务器下运行的代码?

How can I easily work on code that running under the development server?

推荐答案

很久以来，它就被打破了.参见 https://github.com/pypa/pip/issues/3246 和 https://github.com/pypa/pip/issues/562 .

This is known to be broken since a long time. See https://github.com/pypa/pip/issues/3246 and https://github.com/pypa/pip/issues/562.

在第二个链接中，提到一些开发人员用--src替换了--target来覆盖他们的用例.我自己还没有尝试过.

In the second link it is mentioned that some developers covered their use case with replacing --target by --src. I have not tried this myself though.
