SCons 的若干问题

作者:互联网

问题

CentOS7 使用 pip 安装 SCons,默认安装位置是 /usr/local/bin/scons, 库(engine)的默认安装位置是 /usr/local/lib/python3.6/site-packages/scons,但在运行时默认的搜索 engine 的路径不包含安装路径,导致错误。

$ scons
SCons import failed. Unable to find engine files in:
  /usr/local/lib/scons-3.1.2
  /usr/lib/scons-3.1.2
  /usr/local/lib/scons-3.1.2
  /usr/lib/python2.7/site-packages/scons-3.1.2
  /usr/lib64/scons-3.1.2
  /usr/local/lib/scons
  /usr/lib/scons
  /usr/local/lib/scons
  /usr/lib/python2.7/site-packages/scons
  /usr/lib64/scons
Traceback (most recent call last):
  File "/usr/local/bin/scons", line 195, in <module>
    import SCons.Script
ImportError: No module named SCons.Script

解决方法

如下建立软链接,

$ sudo ln -fs /usr/local/lib/python3.6/site-packages/scons /usr/local/lib/scons

即可正常使用,

$ scons
scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
gcc -o hello.o -c hello.c
gcc -o hello hello.o
scons: done building targets.
