Question

我正在尝试使用pip安装fsps库。我在Fedora 30上使用Python 3.7.5和pip 19.3.1。我已按照here的说明安装了FSPS，并已安装numpy。但是当我跑步

pip3 install fsps

我收到以下错误

我确实将SPS_HOME=/path/to/fsps/和export SPS_HOME添加到了.bashrc中，并且已编译的.o和.mod文件位于${SPS_HOME}/src中。 echo $SPS_HOME确实显示了路径。

我尝试从source安装。正在运行

git clone https://github.com/dfm/python-fsps.git
cd python-fsps
python setup.py install

引发同样的错误

Traceback (most recent call last):
  File "/home/user/python-fsps/fsps/__init__.py", line 26, in <module>
    ev = os.environ["SPS_HOME"]
  File "/usr/lib64/python3.7/os.py", line 679, in __getitem__
    raise KeyError(key) from None
KeyError: 'SPS_HOME'

During handling of the above exception, another exception occurred:

    raise ImportError("You need to have the SPS_HOME environment variable")
ImportError: You need to have the SPS_HOME environment variable

如何解决此错误并安装FSPS？

Answer 1

我确实将SPS_HOME=/path/to/fsps/添加到了.bashrc

应该将环境变量添加到~/.bash_profile中（尽管~/.bashrc也可以容忍）。

要使环境变量在子流程中可见，必须将其导出。设置变量后添加：

export SPS_HOME

尽管设置了环境变量，但安装FSPS会引发错误
