python - "AttributeError: ' float ' object has no attribute ' 替换 '"安装 python 包时出错

Question

我正在尝试在 Linux Zorin 上安装 python 包 DMRG101。我从 GitHub https://github.com/iglpdc/dmrg101 获取这个包。我安装了 python 2.7.12 和 python 3.5.2。我尝试使用

安装此软件包

python setup.py install

但它给了我以下错误

    running install
    running build
    running build_py
    running install_lib
    running install_egg_info
    Traceback (most recent call last):
      File "setup.py", line 30, in <module>

        dist.run_commands()
      File "/usr/lib/python2.7/distutils/dist.py", line 953, in run_commands
        self.run_command(cmd)

        cmd_obj.run()
      File "/usr/lib/python2.7/distutils/command/install.py", line 613, in run
        self.run_command(cmd_name)
      File "/usr/lib/python2.7/distutils/cmd.py", line 326, in run_command
        self.distribution.run_command(command)
      File "/usr/lib/python2.7/distutils/dist.py", line 971, in run_command
        cmd_obj.ensure_finalized()
      File "/usr/lib/python2.7/distutils/cmd.py", line 109, in ensure_finalized
        self.finalize_options()
      File "/usr/lib/python2.7/distutils/command/install_egg_info.py", line 46, in finalize_options
        to_filename(safe_version(self.distribution.get_version()))
      File "/usr/lib/python2.7/distutils/command/install_egg_info.py", line 88, in safe_version
        version = version.replace(' ','.')
    AttributeError: 'float' object has no attribute 'replace'

如何消除这个错误？

Answer 1

我只需转到 install_egg_info.py 并将此行修改为:

version = str(version).replace(' ','.')

然后，再次重新运行安装命令，它就可以工作了。
