我使用apt get安装它,它现在说3.2.2 - 这是一个违规版本.如何降级到3.1.1？
更新:
install.packages(c("batch", "bitops", "boot", "caTools", "data.table", "doMC", "doSNOW", "ggplot2", "glmnet", "lda", "Matrix", "matrixStats", "moments", "plotrix", "psych", "reshape", "topicmodels", "wordcloud", "methods"), dependencies=TRUE)
Warning messages:
1: package ‘methods’ is not available (for R version 3.2.2)

installation of package …我在Win 7上安装了anaconda PYTHON 2.7 64bit,然后使用更新
conda update conda
后来装了
conda install jupyter
当我试图在Windows上使用相同的驱动器运行时
jupyter notebook
它在Firefox和状态上启动
404: Not Found
按照命令说
Refusing to serve hidden directory via 404 Error
推出它需要做些什么？
更新:anaconda安装有一个运行jupyter的快捷方式,它可以这样工作 - 但为"jupyter notebook"提供了404:
d:\Anaconda\Scripts/ipython-script.py" notebook
我有一个列表 xline。它被初始化，然后被附加。但是我运行时出现错误？
xline = []
---#append
----
print (''.join(xline)) # Convert list into string
运行时错误
print (''.join(xline)) # Convert list into string
TypeError: sequence item 0: expected string, int found
怎么了？
我能够使geolite2在python2.7上工作-但我需要3.4。我在以下链接上找到了2.7的说明：http : //pythonhosted.org/python-geoip/。还提供了代码片段。
pip install python-geoip
pip install python-geoip-geolite2
>>> from geoip import geolite2
>>> match = geolite2.lookup('17.0.0.1')
>>> match is not None
True
因此，我自然将所有pip更改为pip3并安装在新的VM上。代码上没有错误，但是不会从其数据库中拾取并返回值。
pip3 install python-geoip
pip3 install python-geoip-geolite2
在2.7 VM中，当我使用3.4时，我将geoip库指向/usr/local/lib/python2.7/dist-packages-也没有运气。但是，它可以在同一VM上的2.7上运行。
我需要做什么才能使其在3.4上运行？
