使用--prefix时,python-daemon安装失败

Question

如果我执行:

pip install --install-option="--prefix=/root/folder" airflow==1.8.0

它会结束

    'dist_version': self.distribution.get_version(),
  File "version.py", line 656, in get_version
    version_info = self.get_version_info()
  File "version.py", line 651, in get_version_info
    changelog_path = get_changelog_path(self)
  File "version.py", line 552, in get_changelog_path
    setup_dirname = os.path.dirname(distribution.script_name)
  File "/usr/lib64/python2.7/posixpath.py", line 129, in dirname
    i = p.rfind('/') + 1
AttributeError: 'NoneType' object has no attribute 'rfind'

如果我执行

 pip install airflow==1.8.0

它将完成整个过程,没有错误.

由于这必须遇到jenkins构建过程,我不能省略安装选项.任何强大的python用户可以帮助我了解在哪里看到以及如何解决它？

我读过你需要先安装这个库(python-daemon),但是仍然无法使用安装选项:

pip install --install-option="--prefix=/root/folder" python-daemon 

/usr/lib/python2.7/site-packages/pip/commands/install.py:188: UserWarning: Disabling all use of wheels due to the use of --build-options / --global-options / --install-options.

        'dist_version': self.distribution.get_version(),
      File "version.py", line 656, in get_version
        version_info = self.get_version_info()
      File "version.py", line 651, in get_version_info
        changelog_path = get_changelog_path(self)
      File "version.py", line 552, in get_changelog_path
        setup_dirname = os.path.dirname(distribution.script_name)
      File "/usr/lib64/python2.7/posixpath.py", line 129, in dirname
        i = p.rfind('/') + 1
    AttributeError: 'NoneType' object has no attribute 'rfind'

提前致谢.

python-daemon需要docutils.

pip install docutils

在那之后

pip install python-daemon
