安装h5py没有sudo

我想安装h5py包通过pip for python 2.7，我不能使用sudo，我也安装了python 3.2。安装h5py没有sudo

这里是我的学尝试：

我已经安装了PIP：

curl -O https://bootstrap.pypa.io/get-pip.py 
python2.7 get-pip.py --user

然后我安装wheel

~/.local/bin/pip2.7 install --user wheel

Collecting wheel

然后安装h5py，似乎失败了。通过python2.7

我做错了什么

哪个操作系统？你安装了哪个版本的HDF5？ –

@aragilar看到更新。 – mrgloom

这是h5py，而不是HDF5。导入异常抱怨h5py和HDF5之间的连接，这可能是由于某些版本问题。请参阅https：//bugs.launchpad。net/ubuntu/+ source/hdf5/+ bug/1418220，这实际上可能是你的问题。 –

因此，有几件事情发生在这里：

setuptools没有找到wheel缺少SSL证书的问题（见urllib3链接），这意味着车轮没有建成，所以pip电话python setup.py install直接
h5py正试图在HDF5中使用HDF5中不存在的功能，该功能在您系统上的HDF5版本中不存在。

1和2值得修复（因为它们可能是系统中其他问题的症状），但3是原因h5py不适用于您。

h5py正试图访问H5Oexists_by_name。根据https://www.hdfgroup.org/HDF5/doc/RM/RM_H5O.html#Object-ExistsByName，这首先出现在HDF5的1.8.5版本中。根据http://packages.ubuntu.com/source/precise/hdf5，系统上的HDF5版本是1.8.4（但您需要检查！）。不知何故h5py认为你系统上的HDF5库是1.8.5或更高（见https://github.com/h5py/h5py/blob/4ee8f89b6dc658fdea5dc62d0f29058121928cfe/h5py/h5o.pyx#L172）

看起来像别人遇到过类似的问题，并提交https://bugs.launchpad.net/ubuntu/+source/hdf5/+bug/1418220。您可能想告诉他们您的问题，以便他们能够产生错误修复。
