Makefiles无法启动conda环境

Question

I have the makefile

.PHONY: start-generate

start-generate:
    source activate myenv
    mkdir "data_channels_`date +%Y%m%d_%H%M%S`"
    python main/datageneration.py ./"data_channels_`date +%Y%m%d_%H%M%S`" 3

but when I run it I get

$ make start-generate
source activate myenv
make: source: Command not found
make: *** [start-generate] Error 127

although I am able to run source activate myenv outside make.

If I alternatively try

start-generate:
    ( \
        source activate myenv; \
        mkdir "data_channels_`date +%Y%m%d_%H%M%S`"; \
        python main/datageneration.py ./"data_channels_`date +%Y%m%d_%H%M%S`" 3; \
    )

I get the error

/bin/sh: 2: source: not found
Traceback (most recent call last):
  File "main/datageneration.py", line 1, in <module>
    import pandas as pd
ImportError: No module named pandas
make: *** [start-generate] Fehler 1

The error with pandas is obviously, because the source-command did not work. And regarding that there is the message /bin/sh: 2: source: not found . Maybe the issue is that I need /bin/bash instead of /bin/sh ? If so, how do I get it?

What is the issue here?

You can use python in virtualenv directly.

.PHONY: start-generate

start-generate:
    mkdir "data_channels_`date +%Y%m%d_%H%M%S`"
    /absPATH/python main/datageneration.py ./"data_channels_`date +%Y%m%d_%H%M%S`" 3

or you can do like below:

How to use virtualenv in makefile

start-generate:
    ( bash -c "source activate myenv; \
        mkdir "data_channels_`date +%Y%m%d_%H%M%S`"; \
        python main/datageneration.py ./"data_channels_`date +%Y%m%d_%H%M%S`" 3" )
