pip install --user -e /home/me/package/ 权限被拒绝

Question

--editable我正在尝试使用 模式安装本地包pip。当我发出命令时...

$ python3.7 -m pip install --user -e /home/me/my_pkg/

...它正确安装了所有依赖项，但是当它尝试my_pkg自行安装时，我得到以下信息...

    error: can't create or remove files in install directory

    The following error occurred while trying to add or remove files in the
    installation directory:

        [Errno 13] Permission denied: '/usr/local/lib/python3.7/dist-packages/test-easy-install-901889.write-test'

    The installation directory you specified (via --install-dir, --prefix, or
    the distutils default setting) was:

        /usr/local/lib/python3.7/dist-packages/

    Perhaps your account does not have write access to this directory?  If the
    installation directory is a system-owned directory, you may need to sign in
    as the administrator or "root" account.  If you do not have administrative
    access to this machine, you may wish to choose a different installation
    directory, preferably one that is listed in your PYTHONPATH environment
    variable.

    For information on other options, you may wish to consult the
    documentation at:

      https://setuptools.readthedocs.io/en/latest/easy_install.html

    Please make the appropriate changes for your system and try again.

我不明白我怎么会收到该--user标志的权限错误。我不想全局安装这个包，所以使用sudo pip install ...不是一个选项。如何让 pipeditable仅为当前用户安装软件包？

$ python3.7 -m pip --version
pip 21.1.1 from /home/rob/.local/lib/python3.7/site-packages/pip (python 3.7)

这是一个错误。该问题正在 https://github.com/pypa/pip/issues/7953进行跟踪。

目前的解决方法是修改您的setup.py()以包含此内容：

import site
import sys
site.ENABLE_USER_SITE = "--user" in sys.argv[1:]

或者，如果您使用 setup.cfg 或 pyproject.toml，则在命令行上使用类似的内容：

$ python3 -c 'import setuptools, site, sys; site.ENABLE_USER_SITE = 1; sys.argv[1:] = ["develop", "--user"]; setuptools.setup()'
