我想安装一些Python模块,即MATLAB Engine。 MATLAB全局安装在/usr/local/sw/matlab
下,因此我转到相应的目录,然后按链接文档中的说明运行setup.py
。但是,我不是root用户,因此我添加了--user
标志,如官方Python Docs所述。
这就是我得到的:
> python setup.py install --user
running install
running build
running build_py
creating build
error: could not create 'build': Permission denied
显然,它尝试在当前目录中构建模块,而我没有写访问权限。我可以通过运行来回避
python setup.py build --build-base=/path/to/temp/build/dir
但是我不知道如何安装它。另外,由于install
无法识别--build-base
选项,因此我无法将这两种方法结合起来。
我还尝试将整个matlabroot/extern/engines/python
目录复制到其他位置并在其中运行python setup.py install --user
,但这会产生结果
error: The installation of MATLAB is corrupted. Please reinstall MATLAB or contact Technical Support for assistance.
我想它不再找到matlabroot
。
那么如何在没有root的情况下构建和安装位于/usr...
下某个地方的某些源代码?

You can use Virtualenv or venv to deal with this kind of issues.
Edit: As we went a bit deeper into issue itself, we managed to figure out the answer.
If you wish to use virtual environment: python setup.py build --build-base="/path/to/directory_you_can_write_to" install --prefix="/path/to/virtualenv/" --user
If you wish to accomplish what @Feodoran asked for: python setup.py build --build-base="/path/to/directory_you_can_write_to" install --user
