无法在x86_64上从PyPI安装VTK

Posted 2021-04-20

我知道VTK现在可以作为PyPI（https://pypi.python.org/pypi/vtk/8.1.0）的轮子使用，但我无法安装它。有没有解决的办法？

当我尝试这是我得到的：

$ pip install vtk
Collecting vtk
  Could not find a version that satisfies the requirement vtk (from versions: )
No matching distribution found for vtk

我试过指向滚轮的URL，但仍然是同样的问题。

$ pip install https://pypi.python.org/packages/13/7f/735fbc0dd78c91ad3693cfdfe5c91603899fc8e24909f935d46d2fde6559/vtk-8.1.0-cp27-cp27mu-manylinux1_x86_64.whl#md5=49c8d620b2affe2dc2284048659115e5
vtk-8.1.0-cp27-cp27mu-manylinux1_x86_64.whl is not a supported wheel on this platform.

这是我的平台信息：

$ uname -a
Linux [hostname-withheld] 3.10.0-514.16.1.el7.x86_64 #1 SMP Fri Mar 10 13:12:32 EST 2017 x86_64 x86_64 x86_64 GNU/Linux

答案

所以问题与轮文件有文件'manylinux1'的事实有关。

首先，找出pip检查的平台。你可以使用pip中的一个方便的功能（在https://github.com/tensorflow/tensorflow/issues/9722上找到）：

$ python -c 'from pip import pep425tags; print pep425tags.supported_tags'
[('cp27', 'cp27mu', 'linux_x86_64'), ('cp27', 'none', 'linux_x86_64'), ('py2', 'none', 'linux_x86_64'), ('cp27', 'none', 'any'), ('cp2', 'none', 'any'), ('cp26', 'none', 'any'), ('cp25', 'none', 'any'), ('cp24', 'none', 'any'), ('cp23', 'none', 'any'), ('cp22', 'none', 'any'), ('cp21', 'none', 'any'), ('cp20', 'none', 'any'), ('py27', 'none', 'any'), ('py2', 'none', 'any'), ('py26', 'none', 'any'), ('py25', 'none', 'any'), ('py24', 'none', 'any'), ('py23', 'none', 'any'), ('py22', 'none', 'any'), ('py21', 'none', 'any'), ('py20', 'none', 'any')]

第一个结果显示我们应该将'manylinux1'与'linux'交换：

$ wget https://pypi.python.org/packages/13/7f/735fbc0dd78c91ad3693cfdfe5c91603899fc8e24909f935d46d2fde6559/vtk-8.1.0-cp27-cp27mu-manylinux1_x86_64.whl#md5=49c8d620b2affe2dc2284048659115e5

使用符号链接重命名：

$ ln -s vtk-8.1.0-cp27-cp27mu-manylinux1_x86_64.whl vtk-8.1.0-cp27-cp27mu-linux_x86_64.whl

现在安装：

$ pip install vtk-8.1.0-cp27-cp27mu-linux_x86_64.whl

那应该解决它！
