subprocess.CalledProcessError：命令'['which'，'c++']'返回非零退出状态1

Question

请帮助我，困惑了近两天。

File "/data/ywj/Anaconda3/envs/torch/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 252, in check_compiler_abi_compatibility
if not check_compiler_ok_for_platform(compiler):
File "/data/ywj/Anaconda3/envs/torch/lib/python3.6/site-packages/torch/utils/cpp_extension.py", line 212, in check_compiler_ok_for_platform
which = subprocess.check_output(['which', compiler], stderr=subprocess.STDOUT)
File "/data/ywj/Anaconda3/envs/torch/lib/python3.6/subprocess.py", line 356, in check_output
**kwargs).stdout
File "/data/ywj/Anaconda3/envs/torch/lib/python3.6/subprocess.py", line 438, in run
output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['which', 'c++']' returned non-zero exit status 1.
Process finished with exit code 0

我已经在/data/ywj/gcc73/gcc73中安装了gcc/g++7.3.0（非root）

我在服务器上运行该程序没有出现此错误，但是当我远程连接到服务器并在 Pycharm 中运行该程序时，出现此错误。

我猜你正在构建或安装一些软件包。

首先，尝试通过以下方式获取 g++ 的版本：g++ --version。

Copyright (C) 2019 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

然后，为您的构建命令添加前缀CXX=g++-9 CC=gcc-9 LD=g++-9，例如：

CXX=g++-9 CC=gcc-9 LD=g++-9 pip install xxxx

请注意，这9意味着您的 g++ 版本。
