安裝h5py沒有sudo

我想安裝h5py包通過pip for python 2.7，我不能使用sudo，我也安裝了python 3.2。安裝h5py沒有sudo

這裏是我的學嘗試：

我已經安裝了PIP：

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

然後我安裝wheel

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

Collecting wheel

This may cause the server to present an incorrect TLS certificate, which can cause validation failures.

然後安裝h5py，似乎失敗了。通過python2.7

我做錯了什麼

~/.local/bin/pip2.7 install --user h5py

哪個操作系統？你安裝了哪個版本的HDF5？ –

@aragilar看到更新。 – mrgloom

這是h5py，而不是HDF5。導入異常抱怨h5py和HDF5之間的連接，這可能是由於某些版本問題。請參閱https：//bugs.launchpad。net/ubuntu/+ source/hdf5/+ bug/1418220，這實際上可能是你的問題。 –

因此，有幾件事情發生在這裏：

setuptools沒有找到wheel缺少SSL證書的問題（見urllib3鏈接），這意味着車輪沒有建成，所以pip電話python setup.py install直接
h5py正試圖在HDF5中使用HDF5中不存在的功能，該功能在您系統上的HDF5版本中不存在。

1和2值得修復（因爲它們可能是系統中其他問題的症狀），但3是原因h5py不適用於您。

h5py正試圖訪問H5Oexists_by_name。根據https://www.hdfgroup.org/HDF5/doc/RM/RM_H5O.html#Object-ExistsByName，這首先出現在HDF5的1.8.5版本中。根據http://packages.ubuntu.com/source/precise/hdf5，系統上的HDF5版本是1.8.4（但您需要檢查！）。不知何故h5py認爲你係統上的HDF5庫是1.8.5或更高（見https://github.com/h5py/h5py/blob/4ee8f89b6dc658fdea5dc62d0f29058121928cfe/h5py/h5o.pyx#L172）

看起來像別人遇到過類似的問題，並提交https://bugs.launchpad.net/ubuntu/+source/hdf5/+bug/1418220。您可能想告訴他們您的問題，以便他們能夠產生錯誤修復。
