個人的メモです。なぜ治るのかよくわからないです。教えて下さい。

環境

OS: Windows8.1pro
babun: babun version 1.2.0
pip: pip 7.1.2 from /usr/lib/python2.7/site-packages (python 2.7)

エラー内容

platformioをpip使ってインストールしようとしたらエラー出た
コピるの忘れていたので抜粋して

$ pip install platformio
....
child_info_fork::abort: address space needed by 'cygbz2-1.dll' (0x410000) is already occupied
Error [Errno 11] Resource temporarily unavailable while executing command python setup.py egg_info Exception
....
OSError: [Errno 11] Resource temporarily unavailable

対処方法

よくわからないけどネットで調べた結果rebaseall -vををやるといいと書いてあったので試したらうまく行った。
ただしbabun環境ではうまくいかないらしく、一旦終了して直接ashを立ち上げる必要がある。
まず、~~使いたくもない~~cmdを立ち上げ

(環境に合わせてbabunのインストール先を設定してください)
C:\>\Users\hoge\.babun\cygwin\bin\ash
$/bin/rebaseall -v

でずらずらーとなんか出てきて終わったら、cmdを閉じてbabunを立ち上げてください。
すると、

$ pip install platformio
