报错

在执行import gevent时出现下面的错误

ImportError: dlopen(/Users/user/data/code/venv/lib/python3.10/site-packages/gevent/_gevent_c_hub_local.cpython-310-darwin.so, 0x0002): tried: '/Users/liam/code/venv/lib/python3.10/site-packages/gevent/_gevent_c_hub_local.cpython-310-darwin.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64')), '/System/Volumes/Preboot/Cryptexes/OS/Users/user/code/venv/lib/python3.10/site-packages/gevent/_gevent_c_hub_local.cpython-310-darwin.so' (no such file), '/Users/user/c'o'd'e/venv/lib/python3.10/site-packages/gevent/_gevent_c_hub_local.cpython-310-darwin.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64'))

解决办法

出现该错误是因为我电脑是M1 arm架构的CPU, 需要gevent对arm的支持还有一点问题,有两种解决方式

方式1. 切换M1的终端架构
在终端执行arch -x86_64 bash可以直接切换到x86_64架构可以解决一些兼容性问题

user@user ~ % uname -a
Darwin user 22.1.0 Darwin Kernel Version 22.1.0: Sun Oct  9 20:15:52 PDT 2022; root:xnu-8792.41.9~2/RELEASE_ARM64_T8112 arm64

user@user ~ % arch -x86_64 bash
bash-3.2$ uname -a
Darwin user 22.1.0 Darwin Kernel Version 22.1.0: Sun Oct  9 20:15:52 PDT 2022; root:xnu-8792.41.9~2/RELEASE_ARM64_T8112 x86_64

方式2. 源码方式编译安装gevent
执行arch -arm64 pip3 --no-cache-dir install gevent gevent命令可以通过源码编译方式安装兼容arm架构的gevent

如果安装后出现下面的ValueError: greenlet.greenlet size changed错误, 有可能是greenlet的版本和gevent版本不匹配导致的, gevent似乎因为修某个bug回退了greenlet的版本

ValueError: greenlet.greenlet size changed, may indicate binary incompatibility. Expected 160 from C header, got 40 from PyObject

我的版本如下:

gevent                22.8.0
greenlet              1.1.3

安装gevent的命令可以改成 arch -arm64 pip3 --no-cache-dir pip install greenlet==1.1.3 gevent==22.8.0文章来源地址https://www.toymoban.com/news/detail-401463.html
