无法在 python 2.7 上安装垃圾邮件（操作系统：Fedora）

Question

我尝试使用画中画命令安装垃圾邮件，但出现此错误：

 Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/tmp/pip-build-zI4__D/spams/setup.py", line 121, in <module>
    with open(os.path.join(this_directory, 'README.md'), encoding='utf-8') as f:
TypeError: 'encoding' is an invalid keyword argument for this function

所以，我下载了垃圾邮件的压缩文件，并修改了 setup.py 文件以防止编码关键字问题，当我安装库时出现此错误：

    warning: #warning "Using deprecated NumPy API, disable it with " "#define NPY_NO_DEPRECATED_API NPY_1_7_API_VERSION" [-Wcpp]

当我尝试“pip install spams==2.6.1”时，我收到此错误：

Answer 1

第一次升级pip：

pip install -U pip setuptools

SPAMS' setup.py imports numpy 在安装之前，所以首先你必须安装numpy：

pip install numpy

垃圾邮件需要 BLAS 和 LAPACK。您需要安装 Fedora 的库。见https://fedoraproject.org/wiki/PackagingDrafts/BLAS_LAPACK。试试

yum install openblas lapack

然后使用垃圾邮件：

pip install spams==2.6.1
