由於各種原因,我需要在默認位置以外的地方安裝一個python模塊。 pip install --prefix
會看起來正確的事情,但我有問題:pip安裝模塊和備用路徑
$ pip install --prefix /tmp/foo protobuf-3.2.0-cp27-cp27mu-manylinux1_x86_64.whl
$ export PYTHONPATH=/tmp/foo/lib64/python2.7/site-packages
$ python
Python 2.7.5 (default, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import google.protobuf
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named google.protobuf
>>> import sys
>>> sys.path.append('/tmp/foo/lib64/python2.7/site-packages')
>>> sys.path
['', '/tmp/foo/lib64/python2.7/site-packages', '/usr/lib64/python27.zip',
'/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2',
'/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old',

>>> import google.protobuf
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named google.protobuf
但如果我安裝在默認位置(我不能在生產中做):
$ sudo pip install protobuf-3.2.0-cp27-cp27mu-manylinux1_x86_64.whl
$ python
Python 2.7.5 (default, Nov 6 2016, 00:28:07)

>>> import google.protobuf
>>> google.protobuf.__version__
'3.2.0'
我想我的調用pip
命令是錯誤的,或者在運行時需要做其他事情來獲取該模塊。任何意見將不勝感激。
嘗試使用虛擬環境。 python –
