我刚用pip安装了Liblas:

C:\Users\Geri>pip install liblas
Requirement already satisfied (use --upgrade to upgrade): liblas in c:\python27\arcgis10.2\lib\site-packages
Requirement already satisfied (use --upgrade to upgrade): setuptools in c:\python27\arcgis10.2\lib\site-packages (from liblas)

当我想导入模块时,我得到以下内容:

>>> import liblas
Runtime error 
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "C:\Python27\ArcGIS10.2\lib\site-packages\liblas\__init__.py", line 2, in <module>
    from core import get_version

我正在开发HPC环境,并且没有root访问权限.我从源代码安装了laszip.

从源代码安装laszip

module load git
git clone https://github.com/LASzip/LASzip.git
git checkout tags/2.0.2
cd LASzip

在build目录中创建文件.

mkdir build
cd build
module load cmake
module load gcc
cmake .. -DCMAKE_INSTALL_PREFIX=/home/b.weinstein/LASzip/build 
make
make install

添加路径

export LD_LIBRARY_PATH="/home/b.weinstein/LASzip/build/lib:$LD_LIBRARY_PATH"
export PATH="/home/b.weinstein/LASzip/build/bin:$PATH"

确保它在本地工作

(pangeo) [b.weinstein@c30a-s26 bin]$ pwd
/home/b.weinstein/LASzip/build/bin
(pangeo) [b.weinstein@c30a-s26 bin]$ laszip-config --version
2.0.2

转到新目录以测试链接

cd ~
(pangeo) [b.weinstein@c30a-s26 ~]$ laszip-config --version
2.0.2

从python测试

(pangeo) [b.weinstein@c30a-s26 ~]$ python
