我似乎无法破解如何更改setup.py自定义命令中的目录。我的python模块需要opencv,它需要从源代码创建。setup.py自定义命令中的相对路径'不能cd到文件夹'
一切顺利通过CMake
['cmake','-Hopencv',"-Bopencv/build"],
...
-- Configuring done
-- Generating done
-- Build files have been written to: /root/DeepMeerkat/tests/prediction/opencv/build
未来,我只想CD到生成文件夹,并-j4。但setup.py拒绝看到该文件夹。我试过OpenCV的CD /建造,我从/根/ DeepMeerkat /测试/预测试过/ OpenCV的/建造
,但我总是得到
Running command: ['cd', '/root/DeepMeerkat/tests/prediction/opencv/build']
error: [Errno 2] No such file or directory
这只是混乱。
目录肯定存在
[email protected]:~/DeepMeerkat/tests/prediction# /root/DeepMeerkat/tests/prediction/opencv/build/
bash: /root/DeepMeerkat/tests/prediction/opencv/build/: Is a directory
据我知道你需要从目标目录内作出的Makefile。
完整的脚本:
import subprocess
from distutils.command.build import build as _build
import setuptools
class build(_build):
sub_commands = _build.sub_commands + [('CustomCommands', None)]
class CustomCommands(setuptools.Command):
def initialize_options(self):
pass
def finalize_options(self):
pass
def RunCustomCommand(self, command_list):
print('Running command: %s' % command_list)
p = subprocess.Popen(
command_list,
stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
stdout_data, _ = p.communicate()
print('Command output: %s' % stdout_data)
if p.returncode != 0:
raise RuntimeError(
'Command %s failed: exit code: %s' % (command_list, p.returncode))
def run(self):
for command in CUSTOM_COMMANDS:
self.RunCustomCommand(command)
CUSTOM_COMMANDS = [

只是不要让'-C DIR ...'。 – arrowd
