Activate Anaconda Python environment from makefile
提问by Philip O'Brien
I want to use a makefile to build my project's environment using a makefile and anaconda/miniconda, so I should be able to clone the repo and simply run make myproject
我想使用 makefile 使用 makefile 和anaconda/miniconda构建我的项目环境，所以我应该能够克隆 repo 并简单地运行make myproject
myproject: build
build:
@printf "\nBuilding Python Environment\n"
@conda env create --quiet --force --file environment.yml
@source /home/vagrant/miniconda/bin/activate myproject
If I try this, however, I get the following error
但是，如果我尝试此操作，则会收到以下错误
make: source: Command not found
make: *** [source] Error 127
制作：来源：找不到命令
制作：*** [来源] 错误 127
I have searched for a solution, but [this question/answer(How to source a script in a Makefile?) suggests that I cannot use sourcefrom within a makefile.
我已经搜索了一个解决方案，但是 [这个问题/答案（如何在 Makefile 中获取脚本？）表明我不能source在 makefile 中使用。
This answer, however, proposes a solution (and received several upvotes) but this doesn't work for me either
然而，这个答案提出了一个解决方案（并收到了几个赞成票），但这对我也不起作用
( \
source /home/vagrant/miniconda/bin/activate myproject; \)
/bin/sh: 2: source: not found
make: *** [source] Error 127
( \
source /home/vagrant/miniconda/bin/activate myproject; \)
/bin/sh: 2: 来源：未找到
制作：*** [来源] 错误 127
I also tried moving the source activatestep to a separate bash script, and executing that script from the makefile. That doesn't work, and I assume for the a similar reason, i.e. I am running sourcefrom within a shell.
我还尝试将source activate步骤移至单独的 bash 脚本，并从 makefile 执行该脚本。这是行不通的，我假设出于类似的原因，即我source在 shell 中运行。
I should add that if I run source activate myprojectfrom the terminal, it works correctly.
我应该补充一点，如果我source activate myproject从终端运行，它可以正常工作。

I had a similar problem; I wanted to create, or update, a conda environment from a Makefile to be sure my own scripts could use the python from that conda environment.
By default make uses shto execute commands, and shdoesn't know source(also see this SO answer). I simply set the SHELL to bash and ended up with (relevant part only):
我有一个类似的问题；我想从 Makefile 创建或更新 conda 环境，以确保我自己的脚本可以使用该 conda 环境中的 python。
默认情况下，make 使用sh来执行命令，而sh不知道来源（另请参阅此 SO answer）。我只是将 SHELL 设置为 bash 并最终得到（仅相关部分）：
SHELL=/bin/bash
CONDAROOT = /my/path/to/miniconda2
.
.
install: sometarget
source $(CONDAROOT)/bin/activate && conda env create -p conda -f environment.yml && source deactivate
Hope it helps
希望能帮助到你

You should use this, it's functional for me at moment.
你应该使用这个，它现在对我有用。

I had the same problem. Essentially the only solution is stated by 9000. I have a setup shell script inside which I setup the conda environment (source activate python2), then I call the make command. I experimented with setting up the environment from inside Makefile and no success.
我有同样的问题。基本上唯一的解决方案是 9000。我有一个设置 shell 脚本，我在其中设置了 conda 环境（source activate python2），然后我调用了 make 命令。我尝试从 Makefile 内部设置环境，但没有成功。
I have this line in my makefile:
我的makefile中有这一行：
installpy :
./setuppython2.sh && python setup.py install
The error messages is:
错误消息是：
make
./setuppython2.sh && python setup.py install
running install
error: can't create or remove files in install directory
The following error occurred while trying to add or remove files in the
installation directory:
[Errno 13] Permission denied: '/usr/lib/python2.7/site-packages/test-easy-install-29183.write-test'
Essentially, I was able to set up my conda environment to use my local conda that I have write access. But this is not picked up by the make process. I don't understand why the environment set up in my shell script using 'source' is not visible in the make process; the source command is supposed to change the current shell. I just want to share this so that other people don't wast time trying to do this. I know autotoools has a way of working with python. But the make program is probably limited in this respect.
从本质上讲，我能够设置我的 conda 环境以使用我有写访问权限的本地 conda。但这并没有被 make 过程所接受。我不明白为什么在我的 shell 脚本中使用 'source' 设置的环境在 make 过程中不可见；source 命令应该更改当前的 shell。我只是想分享这个，这样其他人就不会浪费时间尝试这样做了。我知道 autotools 有一种使用 python 的方法。但是 make 程序可能在这方面受到限制。
My current solution is a shell script:
我目前的解决方案是一个 shell 脚本：
cat py2make.sh
猫 py2make.sh
#!/bin/sh
# the prefix should be change to the target
# of installation or pwd of the build system
PREFIX=/some/path
CONDA_HOME=$PREFIX/anaconda3
PATH=$CONDA_HOME/bin:$PATH
unset PYTHONPATH
export PREFIX CONDA_HOME PATH
source activate python2
make
This seems to work well for me.
这对我来说似乎很有效。
There were a solutionfor similar situation but it does not seems to work for me:
有类似情况的解决方案，但似乎对我不起作用：
My modified Makefile segment:
我修改后的 Makefile 段：
installpy :
( source activate python2; python setup.py install )
Error message after invoking make:
调用 make 后的错误信息：
make
( source activate python2; python setup.py install )
/bin/sh: line 0: source: activate: file not found
make: *** [installpy] Error 1
Not sure where am I wrong. If anyone has a better solution please share it.
不知道我哪里错了。如果有人有更好的解决方案，请分享。
