问题描述
我写这篇文章是因为我在使用 pip 安装 Pyomo 时遇到问题Mac OSX 10.14 上的 Python 3.6
I am writing because I am having trouble installing Pyomo using pip on Python 3.6 on Mac OSX 10.14
我正在按照此处的安装说明进行操作.
I'm following the installation instructions here.
我可以成功执行第一个命令:
I can successfully execute the first command:
pip install pyomo
但是当我遇到问题时，我应该运行以下命令来安装其他依赖项:
But when I run into trouble when I'm supposed to run the following command to install additional dependencies:
pyomo install-extras
运行此命令会产生以下错误:
Running this command produces the following error:
Traceback (most recent call last):
File "/usr/local/bin/pyomo", line 11, in <module>
sys.exit(main())
File "/usr/local/lib/python3.6/site-packages/pyomo/scripting/pyomo_main.py", line 82, in main
retval = _options.func(_options)
File "/usr/local/lib/python3.6/site-packages/pyomo/scripting/driver_help.py", line 46, in install_extras_exec
pyutilib.subprocess.run(command, tee=True)
File "/usr/local/lib/python3.6/site-packages/pyutilib/subprocess/processmngr.py", line 690, in run_command
th.join()
UnboundLocalError: local variable 'th' referenced before assignment
Google 网上论坛上有一篇关于此的帖子 但还没有解决方案.
推荐答案
这是 Pyomo github 上的一个记录问题:https://github.com/Pyomo/pyomo/issues/243
This is a documented issue on the github for Pyomo: https://github.com/Pyomo/pyomo/issues/243
他们似乎没有解决 pyomo extras 的 pip 安装问题.
They don't appear to have solved the pip installation of pyomo extras.
但是，如果您安装了 conda - https://docs.conda.io/en/最新/
However, if you have conda installed - https://docs.conda.io/en/latest/
您应该能够使用以下终端命令:
You should be able to use the terminal commands from:
https://pyomo.readthedocs.io/en/latest/installation.html
在成功安装 conda 后在终端中运行:
run this in terminal after conda has been successfully installed:
conda install -c conda-forge pyomo.extras
我知道这不是 pip，但这至少是一种解决方法，直到 pyomo 修复他们的文档.
I know this isn't pip, but it's at least a workaround until pyomo fixes their documentation.
- 确认在 python 3.x 和 ubuntu 18.04 上工作
