我有一个包含以下setup.py文件的小项目：
from setuptools import setup, find_packages
setup(
name='jupyterlab-desktop',
version='0.1.0',
author='Peng Cheng',
author_email='pc175@uow.edu.au',
description='... in an app-mode browser',
long_description=open("../README.md").read(),
url='https://github.com/mwouts/jupytext',
packages=find_packages(exclude=['tests']),
scripts=['../jupyter_apps/jupyterlab-app', '../jupyter_apps/jupyternotebook-app'],
# entry_points={'console_scripts': ['jupyter-desktop=jupyterlab-desktop:main']},
install_requires=['jupyterlab >= 0.35.0'],
tests_require=['pytest'],
license='Apache 2.0',
classifiers=['Development Status :: 5 - Production/Stable',
'License :: OSI Approved :: Apache 2.0 License',
'Environment :: Console',
'Framework :: Jupyter',
'Intended Audience :: Developers',
'Intended Audience :: Science/Research',
'Topic :: Text Processing :: Markup',
'Programming Language :: Python',
'Programming Language :: Python :: 2.7',
'Programming Language :: Python :: 3',
'Programming Language :: Python :: 3.4',
'Programming Language :: Python :: 3.5',
'Programming Language :: Python :: 3.6',
'Programming Language :: Python :: 3.7']
)
分别运行python setup.py build和pip install .时，得到以下结果：
(jupyerlab-desktop) peng@peng-ThinkPad-P51s:~/git/jupyerlab-desktop/python$ python setup.py build
running build
running build_py
running build_scripts
(jupyerlab-desktop) peng@peng-ThinkPad-P51s:~/git/jupyerlab-desktop/python$ pip install .
Processing /home/peng/git/jupyerlab-desktop/python
Complete output from command python setup.py egg_info:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-req-build-kg5jwcjs/setup.py", line 9, in <module>
long_description=open("../README.md").read(),
FileNotFoundError: [Errno 2] No such file or directory: '../README.md'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-req-build-kg5jwcjs/
这是怎么回事？完全相同的环境，第一次找到文件，第二次找不到文件。
更新1 ：之后还会出现更多奇怪的事情：
我已经决定绕过long_description并立即构建该软件包，因此我将其注释掉。再次运行pip install .时，遇到以下消息，该消息似乎是由相同的相对路径错误引起的：

如果这表明我的环境已损坏（并且无法在其他任何地方复制），那么是否有办法验证这一假设？
