Python 为什么可以'；我不能在mac上安装枕头吗？它给出了一些错误

下面是安装枕头时出现的错误。我使用的是OSX小牛。 我尝试通过pip安装来安装枕头

航站楼后来被吊死了。问题是我可以尝试用其他方式安装它，但我想知道为什么它不工作

---

更新阻碍我安装的是安装webp。。它总是挂在那里

我明白了。。我在这里实际做的是安装枕头

sudo ARCHFLAGS=-Wno error=未使用的命令行参数在将来的pip安装中出现硬错误

---

我意识到我在webp和little cms上有问题，所以我通过下载软件包手动安装了它们。

这些似乎都可以安全地忽略警告。输出中有错误吗？很难从您提供的内容中分辨出来–如果成功，请尝试使用

python setup.py build\u ext

构建枕头，然后使用

python setup.py build

；然后回来发布任何与pip运行不一致的结果，因为他们可能会告诉你。@RobAgar它只是挂在pip之后installing@fish2000我试着从这里安装必备软件，但在安装webp和littlecms时遇到了麻烦。它只是挂着。。我试着下载它并执行python setup.py build_ext，但仍然出现了与上面相同的错误..你好，Leonid。我使用了您的hack，看起来它已经成功安装，但我无法将其导入python shell，django runserver也不承认它的存在。你知道会发生什么吗？
