运行 UWSGI 时在 SO 中找不到符号 _PyByteArray_Type

【中文标题】运行 UWSGI 时在 SO 中找不到符号 _PyByteArray_Type

【英文标题】：Symbol not found _PyByteArray_Type in SO when running UWSGI

【发布时间】：2020-04-11 16:26:05

【问题描述】：

当关注quickstart UWSGI guide并尝试启动服务器时，出现以下错误：

ImportError: dlopen(/Users/xxxxxxxx/anaconda3/lib/python3.7/lib-dynload/_struct.cpython-37m-darwin.so, 2): Symbol not found: _PyByteArray_Type
  Referenced from: /Users/xxxxxxxx/anaconda3/lib/python3.7/lib-dynload/_struct.cpython-37m-darwin.so
  Expected in: flat namespace

我尝试过的一些事情：

重新安装 UWSGI - pip install --upgrade --force-reinstall --no-binary :all: --no-cache-dir uWSGI==2.0.17 重新安装 anaconda

线索：

应用程序将使用 werkzeug 开发服务器正常运行而不会出现错误。 在 ~/anaconda3/bin/python 解释器中运行 from struct import pack, unpack 不会导致错误 '~/anaconda3/bin/python3' 和 '/Users/xxxxxxxx/anaconda3/bin/uwsgi' 都包含符号 (nm /Users/xxxxxxxx/anaconda3/bin/uwsgi | grep _PyByteArray_Type)

我该如何解决这个问题？如果这是一个新问题，我应该在哪里报告？ Conda 编译 Python 的方式有问题吗？ UWSGI？

系统：

操作系统：OSX 10.15.2 康达：4.7.12 UWSGI：2.0.18 架构：x86_64

【问题讨论】：

你好，你有解决这个问题的办法吗？除了完全卸载 anaconda，因为我的项目依赖于它

【参考方案1】：

我遇到了同样的问题，完全用remove Anaconda python 解决了它，并通过自制软件安装了python（brew install python）。
