“Psycopg2的建筑轮胎失败” - MacOSX使用virtualenv和pip [英] "Failed building wheel for psycopg2" - MacOSX using virtualenv and pip

问题描述

我试图与其他几个人建立网站，并尝试使用Django / Python / VirtualEnv时遇到了一个奇怪的错误。我已经找到了解决这个问题的其他操作系统，如Ubuntu，但找不到任何好的解决方案的Mac。

这是正在运行的相关代码：

  virtualenv -p python3 venv 
 source venv / bin / activate 
 pip install -r requirements.txt 
  

运行该块后，我收到以下错误：

AssertionError

---

django-toolbelt
运行setup.py bdist_wheel为psycopg2

...

AssertionError

---

无法构建psycopg2
无法构建django-toolbelt psycopg2

我相信我已经安装django-toolbelt和psycopg2，所以我不知道为什么会失败。

我可以想到的唯一区别是我没有使用命令

  sudo apt-get install libpq-dev 
  

按照Ubuntu的使用指示，用brew安装postgresql照顾了标题。

感谢任何帮助或见解！

解决方案

我在Arch linux上也有同样的问题。我认为这不是一个操作系统依赖的问题。无论如何，我通过找到过时的包和更新来解决这个问题。

  pip uninstall psycopg2 
 pip list --outdated 
 pip install --upgrade wheel 
点安装 - 升级setuptools 
点安装psycopg2 
  

希望这有助于...

I'm attempting to make a website with a few others for the first time, and have run into a weird error when trying to use Django/Python/VirtualEnv. I've found solutions to this problem for other operating systems, such as Ubuntu, but can't find any good solutions for Mac.

This is the relevant code being run:

virtualenv -p python3 venv
source venv/bin/activate
pip install -r requirements.txt

After running that block, I get the following errors:

AssertionError

---

Failed building wheel for django-toolbelt Running setup.py bdist_wheel for psycopg2

...

AssertionError

---

Failed building wheel for psycopg2 Failed to build django-toolbelt psycopg2

I believe I've installed the "django-toolbelt" and "psycopg2", so I'm not sure why it would be failing.

The only difference I can think of is that I did not use the command

sudo apt-get install libpq-dev

as was instructed for Ubuntu usage as I believe that installing postgresql with brew took care of the header.

Thanks for any help or insight!

解决方案

I had the same problem on Arch linux. I think that it's not an OS dependant problem. Anyway, I fixed this by finding the outdated packages and updating then.

pip uninstall psycopg2
pip list --outdated
pip install --upgrade wheel
pip install --upgrade setuptools
pip install psycopg2

hope this helps...
