pycharm在`pydevd_cython_darwin_310_64.cpython-310-darwin.so mac上的调试失败的原因是: m1不兼容体系结构

Question

我刚刚升级到pycharm 2022.01，并在使用m1 mac调试python程序时出错：

Traceback (most recent call last):
  File "/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev/_pydevd_bundle/pydevd_cython_wrapper.py", line 8, in <module>
    from _pydevd_bundle_ext import pydevd_cython as mod
ModuleNotFoundError: No module named '_pydevd_bundle_ext'

During handling of the above exception, another exception occurred:

Process finished with exit code 1

我安装了正确版本的吡喃。无法在pypi上找到正确的.so版本。我怎么才能解决这个问题？是否可以为arm64e重新编译pydevd？

Answer 1

成功地重建了与pydevd一起提供的PyCharm：

重建二进制文件

确保安装了cython以更新和编译cython源代码：

sudo pip3 install cython
export PYTHONPATH=/Applications/PyCharm.app/Contents/plugins/python/helpers/pydev:$PYTHONPATH
cd /Applications/PyCharm.app/Contents/plugins/python/helpers/pydev
python3.10 build_tools/build.py

之后，PyCharm中的调试工作进行得很好。

检查二进制文件

重建工作显然是做了什么：

_pydevd_bundle/pydevd_cython.cpython-310-darwin.so

• 删除了仅创建的_pydevd_bundle/pydevd_cython_darwin_*.so文件

使用file命令确认二进制文件具有新的M1 (苹果硅)芯片所需的体系结构：

file _pydevd_bundle/pydevd_cython.cpython-310-darwin.so`

它应该输出M1所需的体系结构，如下面的arm64：

_pydevd_bundle/pydevd_cython.cpython-310-darwin.so: Mach-O 64-bit bundle arm64

Answer 2

作为一个快速修复，您可以简单地禁用cython调试。这仍然使您能够运行调试会话，尽管功能较少。

在PyCharm中将其添加到运行配置的环境变量中：

PYDEVD_USE_CYTHON=NO
