安裝scrapy時出現gcc失敗錯誤

當我安裝scrapy時，我得到下面的錯誤（命令'gcc'失敗，退出狀態爲1）。我使用的是Centos，是的，我已安裝最新版本的gcc。但我不知道爲什麼我得到這個錯誤。我試着用搜索引擎，但could'nt找到一個解決方案安裝scrapy時出現gcc失敗錯誤

OpenSSL/crypto/crypto.c: In function ‘initcrypto’: OpenSSL/crypto/crypto.c:817: warning: implicit declaration of function ‘ERR_load_crypto_strings’ OpenSSL/crypto/crypto.c:818: warning: implicit declaration of function ‘OpenSSL_add_all_algorithms’ OpenSSL/crypto/crypto.c:832: error: ‘crypto_X509_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:833: error: ‘crypto_X509Name_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:834: error: ‘crypto_X509Req_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:835: error: ‘crypto_X509Store_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:836: error: ‘crypto_PKey_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:838: error: ‘crypto_PKCS7_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:839: error: ‘crypto_NetscapeSPKI_New’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:859: error: ‘X509_FILETYPE_PEM’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:860: error: ‘X509_FILETYPE_ASN1’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:863: error: ‘EVP_PKEY_RSA’ undeclared (first use in this function) OpenSSL/crypto/crypto.c:864: error: ‘EVP_PKEY_DSA’ undeclared (first use in this function) error: Setup script exited with error: command 'gcc' failed with exit status 1

我也收到同樣的錯誤，當我安裝LXML

您是否使用'easy_install'安裝？ –

太本地化，不具建設性。 – markus

您沒有必要的C庫編譯這個模塊。對於lxml，您必須安裝以下軟件包。

sudo yum install python-devel libxml2-devel libxslt-devel

要解決的OpenSSL問題Scrapy，安裝pyOpenSSL

sudo yum install pyOpenSSL

注：這些是Fedora Linux系統的包名。其他發行版可能具有不同的軟件包名稱。

在Debian上：'sudo apt-get install python-dev libxml2-dev libxslt-dev' – phirschybar

這是對Linux Mint的納迪亞，我的解決方案：

sudo apt-get install libxml2-dev libxslt-dev

我已經有蟒蛇-dev的安裝。我注意到，一旦安裝了xml和xslt依賴項，pip就能爲我安裝pyOpenSSL。

'sudo apt-get install libxml2-dev libxslt-dev' –

另外，還要確保你已經安裝GCC：

sudo yum install gcc

我raspi自動更正爲

sudo apt-get install libxml2-dev libxslt1-dev

我也跑：

sudo apt-get install libffi-dev

不知道這是否是neccessary。

在Fedora 23上，我必須安裝以下軟件包才能成功完成$ pip install scrapy。

sudo dnf install python-devel libxml2-devel libxslt-devel libffi-devel libffi-devel

如果安裝程序報告缺少文件，例如：

fatal error: openssl/opensslv.h: No such file or directory 
    compilation terminated. 
    error: command 'gcc' failed with exit status 1

做$ dnf provides *filename（DNF提供*的OpenSSL/opensslv.h）找到所需的軟件包並安裝它。
