PyCurlがインストールされているが

Question

私はeasy_installを持つvirtualenvのでpycurlをインストールしようとしてきたが見つかりません、正しくインストールするために表示されます。使用しようとすると

この問題を解決する方法についてのご意見は、高く評価されます。

配布はAmazon Linux（EC2,64ビット）、Pythonは2.7、ソースからインストールされています。 curl、libcurl、libcurl-devはすべてAmazon yum reposによって提供され、バージョン7.19.7-26.20になります。

pythonのディストリビューションバージョンが2.6で、私のプロジェクトが2.7で動作するため、Amazon reposが提供するpycurlパッケージをインストールできません。 （いくつかの助けを借りて）

Answer 1

私が管理しているので、問題を解決するため、次のよう

それはパスの問題ではありませんが、のsys.pathの内容があります。問題は、インストール後、pycurl.soがこのvirtualenvのサイトパッケージにコピーされないということです。

pip -v install pycurl経由でインストールする場合、次の出力が与えられます。ここで

キーエラーは次のとおりです。curl-configが、それが失敗した引数--static-libs、と呼ばれていることを示して gcc -pthread -shared build/temp.linux-x86_64-2.7/src/pycurl.o -L/opt/python2.7/lib -lcurl -lpython2.7 -o build/lib.linux-x86_64-2.7/pycurl.so unknown option: --static-libs Usage: curl-config [OPTION] Available values for OPTION include: --ca ca bundle install path --cc compiler --cflags pre-processor and compiler flags --checkfor [version] check for (lib)curl of the specified version --features newline separated list of enabled features --help display this help and exit --libs library linking information --prefix curl install prefix --protocols newline separated list of enabled protocols --version output version information --vernum output the version information as a number (hexadecimal)

代わりにそれを認識し、それを印刷します。最も重要なのは、非エラーコードの出力を返しているため、コンパイラはpycurl.soのコンパイルが成功したとみなします。

これは、より詳細にhere

に記載されているこの問題を解決するには、--libs代わりの--static-libsを読み取るためにpycurlのsetup.pyと変更ライン101を変更することでした。これにより、pycurl.soが構築され、site-packagesディレクトリに正常にコピーされます。

Answer 2

この問題に関する2015年のアップデート。
私はこのインストールPycurlに、ヨセミテを走らせているMacで走った。以下に示すように、私はsetup.pyにラインを変更：

for option in ["--libs", "--static-libs"]: 

へ：

for option in ["--libs"]: 

次に走っ：

$>python setup.py install 

インストールは、この後に完全に働きました！
