Anaconda 如何删除产生冲突的protobuf编译器之一？

我已经使用这个

conda安装protobuf==2.6.1

在conda环境中安装了protobuf。因此，一旦我想安装一个软件，它就会显示以下错误消息：

 #error This file was generated by a newer version of protoc which is
 #error This file was generated by a newer version of protoc which is
  ^
.build_release/src/caffe/proto/caffe.pb.h:13:2: error: #error incompatible with your Protocol Buffer headers. Please update

compilation terminated.
Makefile:588: recipe for target '.build_release/src/caffe/proto/caffe.pb.o' failed
make: *** [.build_release/src/caffe/proto/caffe.pb.o] Error 1

我试图找出安装了哪些版本的protobuf

$sudo find / -name protoc
/usr/share/bash-completion/completions/protoc
find: ‘/run/user/1000/gvfs’: Permission denied
/home/ubuntu/anaconda2/pkgs/libprotobuf-3.4.1-h5b8497f_0/bin/protoc
/home/ununtu/anaconda2/envs/testenv/bin/protoc

通过此命令卸载protobuf后，即使在删除编译器后，conda uninstall protobuf：

sudo apt-get remove protobuf-compiler
sudo apt-get remove --auto-remove protobuf-compiler
$ protoc --version   ===>>> libprotoc 3.4.0

---

如何卸载此libprotoc 3.4.0？即使通过此命令

sudo apt get autoremove protobuf compiler libprotobuf dev

删除并成功删除，它仍将protoc版本显示为

libprotoc 3.4.0

。有人能帮忙吗？我只需要

protobuf==2.6.1

。谢谢

我可以解决蟒蛇环境中的问题：

conda uninstall libprotobuf
