Httpie: Brew安装的版本不适用于插件

@rshurts你是对的。 基于Homebrew的安装的插件安装无法立即使用。

但是，将Homebrew保留为推荐方法有很多好处。 它使更新变得容易，并且主程序包可以依赖于Python 3（改进的SSL支持等）。

理想的世界解决方案是将所有插件作为Homebrew软件包（ brew install httpie-oauth ）提供。 但这对于维护人员而言意味着额外的工作，因此并非所有插件都可以在Homebrew中使用。

使用pip安装插件似乎更简单。 要使其与Hombrew一起使用，将意味着指示pip （当前）使用/usr/local/Cellar/httpie/0.9.8_2/libexec/lib/python3.6/site-packages作为安装目录。

但是在那里安装的插件将无法承受HTTPie升级。

也许可以调整Homebrew公式，以允许从例如Homebrew Python 3 site-packages （不确定是否是永久性的）中通过HTTPie加载已安装的插件。 或从另一个位置。

…或某种自定义插件安装程序。

同时，也许有关插件的文档中有一条注释说“ brew不适用于插件，并且为插件功能点点安装httpie”会省些麻烦。

当用户没有管理员权限时，读取权限也存在问题：

我能够用

chmod +r /usr/local/Cellar/httpie/1.0.0/libexec/lib/python3.7/site-packages/idna-2.7-py3.7.egg-info/PKG-INFO

但改用pip3 install httpie是因为它使安装插件更加容易。

自从我升级到10.14 Mojave之后，我遇到了@aheissenberger上面提到的权限错误。 我具有使用本地管理员帐户安装自制软件的相同设置，但在标准帐户中可以正常运行。 我不是Python的人，也不了解关于插件的讨论。 我不记得尝试添加任何自家自制配方之外的东西了。 pip3 list仅显示3个项目，这些项目大概是初始Python捆绑包的一部分。

这从根本上来说是一个Python3问题（至少是通过自制软件安装的Python）吗？ 我应该向维护者报告它吗？

对于它的价值，也许其他用户正在寻找答案，安装插件对我来说很好用，如下所示：

pip3 install -t /usr/local/Cellar/httpie/2.0.0/libexec/lib/python3.8/site-packages httpie-jwt-auth
