一. conda踩坑記錄1.An unexpected error has occurred. Conda has prepared the above report

想更新deeptools，但是發(fā)現(xiàn)無(wú)論如何都下載不了，并且有以下報(bào)錯(cuò)

解決辦法：

1、有人說(shuō)是防火墻的問(wèn)題，輸入conda config --set ssl_verify false

還是不行

2、有人說(shuō)conda損壞，重裝，，，，想想還是算了，太麻煩

3、終極解決辦法：輸入 conda clean -i

完美解決?。?/p>

詳情見(jiàn) 三. Conda無(wú)法安裝或更新的問(wèn)題

三. Conda無(wú)法安裝或更新的問(wèn)題

用conda安裝任何東西都報(bào)錯(cuò). 開(kāi)始懷疑是公司的鬼網(wǎng)絡(luò)問(wèn)題.

將.condarc重命名, 重新嘗試, 一切又很正常, 以為是清華源TUNA的問(wèn)題, 還想去https://github.com/tuna/ 報(bào)錯(cuò).

后來(lái)一次將https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r channel一行在.condarc中刪掉后, 一切又正常了. 莫名其妙啊…

最開(kāi)始時(shí)懷疑是 raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)的問(wèn)題, 以為是清華源那邊缺失channeldata.json導(dǎo)致找不到subdir, 但關(guān)鍵的文件是repodata.json還是存在且一樣的. 可能不是TUNA的問(wèn)題.

• 官方pkgs/r源 https://repo.anaconda.com/pkgs/r

• 清華pkgs/r源 https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r/

于是重新仔細(xì)追查錯(cuò)誤, 發(fā)現(xiàn)這個(gè)錯(cuò)誤有三處:

• raise UnavailableInvalidChannel(self.url_w_repodata_fn, 404)

• raise Response304ContentUnchanged()

• json.decoder.JSONDecodeError: Unterminated string starting at: line 184947 column 5 (char 5586731)

第一個(gè)網(wǎng)絡(luò)是可以下載對(duì)應(yīng)repodata.json的, 第二個(gè)304重定向應(yīng)該不是, 第三個(gè)是json解碼的問(wèn)題. 搜了一下, 找到以下帖子:

JSONDecodeError with on-disk corrupted repodata #7190

噢, 原來(lái)還是公司網(wǎng)絡(luò)的鍋. 肯定是之前update repo信息時(shí)網(wǎng)絡(luò)有問(wèn)題, 于是就出現(xiàn)了污染.

解決辦法

conda clean -i

然后重新隨便install 個(gè)東西, 會(huì)重新下載repo信息. 問(wèn)題解決. NND的公司網(wǎng)絡(luò)…

附錯(cuò)誤內(nèi)容:

$ conda install numpy

原因：連不上清華的鏡像。

按照網(wǎng)上的方法刪除 -default 也沒(méi)有用。

修改方法：

使用下面兩個(gè)命令，將中科大的鏡像加到目錄中去

$conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
$conda config --set show_channel_urls yes

然后打開(kāi)./刪除其他所有鏡像，以及default

$vim ~/.condarc

修改后：

然后就可以了！

看網(wǎng)上有人說(shuō)，把https 改為http也行，沒(méi)試，不知道可行否
