本地主机上的应用程序引擎 std 的 devappserver.py 正在清除 OS.uname 并在 ctypes 中崩溃

Question

我愚蠢地重新安装了所有Python 2.7依赖项，但它破坏了一些东西。如果您在第1行注意到，os.uname((有一个有效值，但当GAE调用ctypes模块(第3行(时，它已经被清空，我的本地服务器不会响应客户端。

这感觉有点过头了&如果有任何指导，我将不胜感激。

os.uname() is: 19.3.0

Answer 1

attrs自19.2.0以来就没有使用过ctypes，因此解决方案是以某种方式更新您的依赖关系。

Answer 2

尝试编辑位于devappserver2/python/runtime中的stub文件。

google_appengine/google/appengine/tools/devappserver2/python/runtime/stubs.py

发件人：

    def fake_uname():

      """Fake version of os.uname."""

      return ('Linux', '', '', '', '')

收件人：

    def fake_uname():
      """Fake version of os.uname."""
      return ('Linux', 'local', '19', 'Darwin Kernel Version 19', 'x86_64')

这不是一个很好的长期解决方案，因为对gcloud工具链的更新可能会消除这些更改。
