我安装了visual studio,例如我可以安装lxml,但它对PyCrypto和MySQL-python不起作用。
我收到以下错误:
File "C:\Python27\lib\distutils\msvc9compiler.py", line 473, in compile
self.initialize()
File "C:\Python27\lib\distutils\msvc9compiler.py", line 383, in initialize
vc_env = query_vcvarsall(VERSION, plat_spec)
File "C:\Python27\lib\distutils\msvc9compiler.py", line 299, in query_vcvarsal
l
raise ValueError(str(list(result.keys())))
ValueError: [u'path']
我已安装的软件包列表:
D:\>pip list
ipython (2.1.0)
lxml (3.3.5)
mysql-python (1.2.4
pip (1.5.6)
pyasn1 (0.1.7)
pywin32 (218)
rsa (3.1.4)
setuptools (5.4.1)
virtualenv (1.11.6)
wheel (0.24.0)
导致我的错误的原因是什么?
