我尝试执行pip3 install psycopg2

但是出现了以下错误，我不知道该怎么做。

请帮忙解决。

@HimanshuPoddar 这个项目使用 django 框架，需要 psycopg2 作为依赖。因此我已经添加了 django 标签。 同时我已经正确格式化了错误信息。现在可以帮忙吗？ - Amol Chakane

我可以通过安装上面评论中指示的二进制库来解决这个问题。（只是有一个拼写错误）

pip install psycopg2-binary

Amol Chakane提到的错误是指由于拼写错误而找不到软件包而引起的PIP错误。

还要确保您的pip命令引用了正确的Python版本。 在我的情况下，我正在使用一个带有Python 3的环境，因此不需要指定pip3，只需使用pip即可。

谢谢你的帮助。 - analyst_47

如果你是新手（就像我一样）学习Django，你可能想尝试使用psycopg2-binary代替。它适用于开发人员和测试，但不适用于生产环境。我在Mac OS Mojave上的虚拟环境中使用相同版本的Python（3.7），Django版本为2.2.6。我也无法在我的系统上安装pyscopg2。

pip install pyscopg2-binary

这些是我用来帮助自己解决问题的文档：http://initd.org/psycopg/docs/install.html#install-from-source https://pypi.org/project/psycopg2-binary/

我已经尝试过了，但是它给了我一个错误。 Amols-Air：〜amolchakane$ pip install pyscopg2-binary ERROR: Could not find a version that satisfies the requirement pyscopg2-binary (from versions: none) ERROR: No matching distribution found for pyscopg2-binary 而且我希望它也能用于生产。 - Amol Chakane
似乎xcrun和gcc错误很重要。@Housemd在这里使用了相同类型的xcrun和gcc错误修复了自己的解决方案：https://apple.stackexchange.com/questions/254380/why-am-i-getting-an-invalid-active-developer-path-when-attempting-to-use-git-a - codegrrl
