尝试通过以下方法安装Apache Airflow时出现以下错误
<form action="/users" method="post">
<%= hidden_field_tag :authenticity_token, form_authenticity_token %>
<input type="text" name="user[name]" placeholder="Name"><br>
<input type="text" name="user[email]" placeholder="Email"><br>
<input type="password" name="user[password]" placeholder="Password"><br>
<input type="password" name="user[confirm_pw]" placeholder="Confirm PW">
<input type="submit" value="Join">
</form>
我删除了命令行工具，将操作系统从Mojave升级到Catalina，使用pip install apache-airflow重新安装了xcode，即使以下错误未能得到解决：-
xcode-select --install答案 0 :(得分：0)
在Github https://github.com/giampaolo/psutil/issues/1388和https://github.com/cython/cython/issues/2009上阅读这些问题
将我的文件夹---many similar lines---

重命名为/usr/local/include，以备备份之用，以防万一这不起作用
/usr/local/include_old
然后再次运行相同的安装命令：-
mv /usr/local/include /usr/local/include_old
这次完美无瑕。
